Concurrency control (CC) algorithms targeted at web systems need to be different from that of traditional transactional processing systems. In web systems, transactions could be generated in a burst mode, leading to scalability problems at the server. Transactions may also suffer from network delays due to the unpredictable response time over the web. This paper proposes a CC mechanism for web-based three tier systems. In this mechanism, initial validation of the transactions is performed at the application server. The transactions that pass the initial validation are sent to the database server (DB server) for final validation. The serializability criterion is achieved by associating a data-counter with each data-item. This reduces the load on the DB server. Also, in the proposed model, the middle tier contains multiple number of application servers. A part of the database is dynamically replicated in these servers. The modifications made on the data-items are known immediately to clients and the data-items at the DB server are locked only during the final validation phase and write phase. Consequently, the model is also suitable for transactions that suffer from unpredictable delays between read and write operations. The model is scalable as it can support large number of application servers hi the middle tier. Performance studies have been carried out to depict the efficiency of the proposed model over the existing models. The proposed model is simple to implement and it performs extremely well compared to existing models when the transactions are generated in a burst mode.

A role paradigm conformance model (RPCM) called Typehole model was developed and implemented in Java. It does not use Is-role-of inheritance and is free from the object schizophrenia (OS) problem (OSP). An extended distributed role model provides multifarious role hierarchies at different sites. Modeling object role systems is prone to OSP. OSP is the error in the RPCM design to subscribe to the viewpoints in the client space. OS and OSP are contrasted. A classification of OSPs is made. Role modeling problem is the requirement to design an OSP-free RPCM with Is-role-of inheritance. The existing object-oriented role models have been evaluated as regards OSP. No role model has strong claims as regards solving the role modeling problem. A security model was developed for RPCM-based distributed object systems and implemented on CORBA. By designing message filter hierarchies, hybrid security is developed at global and local levels for RPCM-based object systems. Role is either abstract or concrete as it can be a type or an instance.

Complex systems such as those in evolution, growth and depinning models do not evolve slowly and gradually, but exhibit avalanche dynamics or punctuated equilibria. Self-Organized Criticality (SOC) and Highly Optimized Tolerance (HOT) are two theoretical models that explain such avalanche dynamics. We have studied avalanche dynamics in two vastly different grid computing systems: Optimal Grid and Vishva. Failures in optimal grid cause an avalanche effect with respect to the overall computation. Vishva does not exhibit failure avalanches. Interestingly, Vishva exhibits load avalanche effects at critical load density, wherein a small load disturbance in one node can cause load disturbances in several other nodes. The avalanche dynamics of grid computing systems implies that grids can be viewed as SOC systems or as HOT systems. An SOC perspective suggests that grids may be sub-optimal in performance, but may be robust to unanticipated uncertainties. A HOT perspective suggests that grids can be made optimal in performance, but would then be sensitive to unanticipated perturbations. An ideal approach for grid systems research is to explore a combination of SOC and HOT as a basis for design, resulting in robust yet optimal systems. © 2005 The authors. All rights reserved.

With the advancement of technology in micro-electronics and wireless communication, small miniature devices called sensor nodes can be used to perform various tasks by forming themselves in to wireless sensor networks. In Wireless Sensor Networks(WSN), event detection is one of the main requirements for most of the applications. An event can be a simple event or a combination of two or more simple events (Composite Event). Detecting and reporting an event desired by the application (user) inspite of stringent constraints of sensor nodes like low energy, low bandwidth, frequent failures etc., is one of the main challenges in WSN. This can be achieved with less uncertainty and masking failures by considering collaboration among sensor nodes. We propose a framework for distributed event detection using collaboration in WSN. The framework consists of two protocols that build a tree by using a communication model similar to the Publish-Subscribe paradigm. This framework is a part of Component Oriented Middleware for Sensor networks (COMiS). In COMiS framework, components are loaded as and when required based on the application semantics. If collaboration is considered, the goal of the application can be easily accomplished even in case of failures of sensors and low energy of nodes. Copyright 2005 ACM.

Today, a typical telemedicine system involves a small set of hospitals providing remote healthcare services to a small section of the society using nodal centers, mobile health units, etc. However, the benefits of a telemedicine system increase with scale. One of the key requirements of such a large scale system is to allow large numbers of patient medical records, in the form of electronic files, to be efficiently stored and accessed from widely distributed locations. In this paper, we address the need for a distributed file system to manage patient data in large scale telemedicine systems. We use the resources of unreliable Internet edge nodes distributed among hospitals, labs, etc., to provide reliable file system services to patients and doctors. Besides building an Internet-based system that scales with the number of nodes and files, we also attempt to optimize record access times for doctors to provide timely responses.

Data reliability is an important issue from the user's perspective, in the context of streamed data in wireless sensor networks (WSN). Reliability is affected by the harsh environmental conditions, interferences in wireless medium and usage of low quality sensors. Due to these conditions, the data generated by the sensors may get corrupted resulting in outliers and missing values. Deciding whether an observation is an outlier or not depends on the behavior of the neighbors' readings as well as the readings of the sensor itself. This can be done by capturing the spatio-temporal correlations that exists among the observations of the sensor nodes. By using naïve Bayesian networks for classification, we can estimate whether an observation belongs to a class or not. If it falls beyond the range of the class, then it can be detected as an outlier. However naïve Bayesian networks do not consider the conditional dependencies among the observations of sensor attributes. So, we propose an outlier detection scheme based on Bayesian Belief Networks, which captures the conditional dependencies among the observations of the attributes to detect the outliers in the sensor streamed data. Applicability of this scheme as a plug-in to the Component Oriented Middleware for Sensor Networks (COMiS) of our early research work is also presented. © 2006 IEEE.

distributed mobile systems are characterized by asymmetry in both network connectivity and computing power, mobility of hosts and their constraints. To address these issues, existing approaches attempt to completely redesign distributed applications or algorithms to make them work in a distributed mobile environment. This paper proposes an alternate mechanism namely, the surrogate object model to handle the asymmetry problem in distributed mobile systems. The surrogate object is a representative for a particular Mobile Host (MH) in the wired network that maintains application specific data structures and methods. The surrogate object model maintains a cache of data stored in the mobile host and reduces wireless data transfers. The proposed novel model also provides an ideal placeholder for MH location information, thus solving the location management problem to handle mobility of hosts. A comprehensive simulation study of the surrogate object model has been done. Performance studies of a sample application with and without the surrogate object model illustrates the efficiency of developing applications over the surrogate object model. © 2005 Gesellschaft fur Informatik (GI).

Applications like weather forecasting and prediction, health-care monitoring, habitat monitoring, tsunami-warning systems, demand integration of Wireless Sensor Networks (WSNs) with grids. The issues that need to be addressed are, providing suitable programming platform, seamless networking, data management, service/resource discovery etc. objective of this work is to provide a programming model for this integrated network. We propose a programming model built using e-Petri Net, an extension to the classical Petri Net. We define the meta model for the e-Petri Net using Generic Modeling Environment (GME) tool. This meta-model gives the flexibility in understanding and analysing the application before hand. © 2007 IEEE.

object schizophrenia problem in object role system design

This paper argues for strong notions of object Schizophrenia (OS) and object Schizophrenia Problem (OSP) and makes subtle distinction between them. It presents how OSP can occur in modeling ispart- of and is-role-of relationships. Basically, we assert that OS-condition of an object does not necessarily entail OSP. The occurrence of OSP is investigated in the realm of role modeling. Broken consultation, wrong message interpretation and security schizophrenia problem that arise due to reusing mechanisms in role modeling such as delegation are incorporated as new symptoms into the semantic scope of the notion of OSP. We introduce plurality of OS and OSP by categorizing OSs and OSPs based on various models for object relationships and OSP symptoms. A comparison picture of the existing role models is presented with regard to OSP. We assert that there can be different approaches for handling the OSP and that a solution to OSP works out only in a model-specific way. In the realm of role modeling, this work emphasizes that modeling the role paradigm should ensure that the role model is OSP-free. We argue for strong notion of object identity for role-playing objects in terms of the Oid integrity principle. © Springer-Verlag Berlin Heidelberg 2002

Enabling design evolution in software through pattern oriented approach

Architectural erosion in software systems results due to the drifting of code from the existing design. This drifting happens because the changes in code supporting evolving requirements, are not reflected back in the design. The ability to control software artifacts produced in various stages of the software development lifecycle is very crucial. Powerful abstractions for modeling software design is essential for supporting evolution. We propose a pattern oriented approach to software development using patterns as building blocks of architecture. We argue that design evolution in software can best be achieved by replacing existing patterns in the design with new patterns addressing present requirements. Support for design evolution by means of a model for pattern substitution is also presented. Using this model, the design is gracefully evolved and the design changes are seamlessly mapped to code thus preventing architectural erosion. © Springer-Verlag Berlin Heidelberg 2003.
