With the advent of smartphones, mobile-devices have evolved as powerful mini-computers. However, they still suffer from two intrinsic shortcomings, namely limited battery-power and inferior processors compared to their laptop counterparts. Several approaches based on cloud-computing have been suggested in the past to augment the performance of mobile devices and overcome these shortcomings. The utility of these approaches is demarcated by the maximum bandwidth and minimum latency that could be achieved in a cloud over the Internet. In this paper we propose MOCLO, a framework that operates upon locally-installed cloud called MOCLETS which is free from majority of shortcomings present in other Internet based cyber-foraging models. The paper also outlines the optimal architecture of mobile-applications to gain maximum benefit from MOCLO. A proof-of-concept prototype of MOCLO has also been implemented. Results have shown significant decrease in battery consumption and processing time of mobile applications leveraging MOCLO APIs. We also outline the significant cyber foraging frameworks proposed so far and where MOCLO stands in comparison to them. Towards the end we discuss the limitations of MOCLO and scalability issues and consider possible solutions for the same.

Opportunistic networks (Oppnets) are a kind of wireless networks that provide the opportunity to have social interaction and obtain data that can be used for message passing decision. The increase observed in the number of people with PDAs and other handset devices equipped with wireless technologies makes the forwarding paradigm and Oppnets scenarios more interesting and challenging. The main challenge in Oppnets is to take efficient routing decisions on securing the delivery of messages to the destination. Cooperation and trust between nodes in the network saves them from malicious attacks. The trust of a node is a basic value that symbolizes the magnitude of its social responsibility in the network, which include helping groups of nodes in message delivery, saving these nodes from malicious attacks, just to name a few. This paper focuses on blackhole attack against the PRoPHET routing protocol for Oppnets. A Trust-based Security Protocol (TSP) is proposed to secure Oppnets against blackhole attacks. Simulation results are provided to support the effectiveness of our proposed TSP approach, in the sense that considerable control is observed in the number of dropped packets, number of messages captured bythe malicious nodes (so-called malicious count) and overhead ratio.

Considered cryptosystems such as Cardano square lattices are characterized by the high-speed encryption in use today Enhanced Programming computers. This is because the number of different variants rapidly increases with the size of a square. In this paper we have shown that, for the size of 20 × 20, the number of such grids exceeds the number of 1.6 × 2 60 Therefore, these systems have sufficient cryptographic resistance. Application of these systems in conjunction with substitution cipher can still more resist cryptographic attacks.

This paper proposes a reduced-complexity downlink multi-channel assignment scheme when feedback links are capacity-limited. The system model treats the case when multiple access points are allocated to serve scheduled users in over-loaded (i.e. dense) pico/femtocell networks. It assumes that the deployed access points can be shared simultaneously and employ isotropic antenna arrays of arbitrary sizes. Moreover, they transmit their data on a common physical channel and can not coordinate their transmissions. On the other hand, each scheduled user can be served by single transmit channel from each active access point at a time, and it lacks coordination with concurrent active users. The scheme operates according to the occupancy of available transmit channels, wherein extensively occupied access points are avoided adaptively, while reducing the load of processing. The operation is linked to a target performance via controlling the observed aggregate interference from the projected set of serving points. Through the analysis, results for the scheduled user outage performance, and the average number of active access points are presented. Numerical and simulations studies clarify the gains of the proposed scheme for different operating conditions.

One of the most significant problems in organizational scholarship is to discern how social collectives govern, organize, and coordinate the actions of individuals to achieve collective outcomes. The collectives are usually interpreted as complex adaptive systems (CAS). The understanding of CAS is more likely to arise with the help of computer-based simulations. In this tutorial, using agent-based modeling approach, a complex adaptive social communication network model is introduced. The objective is to present the underlying dynamics of the system in a form of computer simulation that enables analyzing the impacts of various mechanisms on network topologies and emergent behaviors. The ultimate goal is to further our understanding of the dynamics in the system and facilitate developing informed policies for decision-makers.

The software Assurance Metrics and Tool Evaluation (SAMATE) project at the National Institute of Standards and Technology (NIST) has organized four Static Analysis Tool Expositions (SATE). SATE is designed to advance research in static analysis tools that find security-relevant defects in source code. Briefly, participating tool makers run their tools on a set of programs. Researchers led by NIST analyze the tool outputs. The results and experiences are reported at a workshop. These expositions have accumulated large amounts of data. This collection allowed for the development and validation of practical metrics in regard to static analysis tool effectiveness and independence. In this paper, we discuss the role of the data in determining which metrics can be derived. Specifically, we detail the three characteristics test data should exhibit and explain why the data we use express each combination of two out of these three properties.

Objective: Defect classification is an essential part of software development process models as a means of early identification of patterns in defect inflow profiles. Such classification, however, may often be a tedious task requiring analysis work in addition to what is necessary to resolve the issue. To increase classification efficiency, adapted schemes are needed. In this paper a light-weight defect classification scheme adapted for minimal process footprint - in terms of learning and classification effort - is proposed and initially evaluated. Method: A case study was conducted at Volvo Car Corporation to adapt the IEEE Std. 1044 for automotive embedded software. An initial evaluation was conducted by applying the adapted scheme to defects from an existing software product with industry professionals as subjects. Results: The results showed that the classification scheme was quick to learn and understand - required classification time stabilized around 5-10 minutes already after practicing on 3-5 defects. The results also showed that the patterns in the classified defects were interesting for the professionals, although in order to apply statistical methods more data was needed. Conclusions: We conclude that the adapted classification scheme captures what is currently tacit knowledge and has the potential of revealing patterns in the defects detected in different project phases. Furthermore, we were, in the initial evaluation, able to contribute with new information about the development process. As a result we are currently in the process of incorporating the classification scheme into the company's defect reporting system. © 2012 IEEE.

The use of virtual cluster for High Performance Computing (HPC) work has a great benefit of hiding the complexity of physical infrastructure while providing a familiar HPC environment for users. Nevertheless, setting up one is still a challenging task for most users. In addition, the ability to span a virtual cluster across a multi-site cloud can even create a great potential for users to harness a much higher processing power from the cloud. In this paper, the development of a multi-site virtual cluster cloud is presented. This is done by providing the cloud infrastructures tailored specifically for virtual cluster deployment along with related utilities such as web-interface monitor and command line tools. To realize this infrastructure, an overlay network is created using Virtual Private Network (VPN) technology to merge every site into a single broadcast domain. Moreover, a Multi-tier VPN network topology is proposed to enhance the communication performance among the multi-site cloud. A smart virtual machine scheduling mechanism is introduced to reduce performance degradation caused by network delays. The experimental results show that the virtual cluster works well with highly parallel task with low communication among task. Thus, this technology can be used to support many classes of important HPC applications.

Secure and convenient user identity management is particularly important to the success of EMR, EHR, and PHR systems. Unfortunately, widely-used identity management mechanisms that solely rely on username/password are inadequate to meet the strong security and privacy requirements for protecting sensitive user information and medical data. Two-factor authentication approaches that are more convenient and user friendly than existing solutions have been given top priority in the healthcare sector where the majority of healthcare practitioners and patients are not tech-savvy. In this paper, we present a smartphone-based identity management framework-SIM-to enhance the security and usability of user identity management in healthcare information systems. SIM leverages the popularity and computational power of smartphone. Within the SIM framework, a person employs a smartphone to centrally store and manage her identity credentials and authenticates herself to healthcare applications using two-factor authentication without typing any identity credentials. Moreover, SIM provides patients with a patient-controlled authorization mechanism to help patients manage the accesses to their PHRs in a secure and convenient manner. Using an existing EMR system-Arkansas Trauma Image Repository-as an example, we demonstrate that SIM can be applied to a real-world healthcare information system to enhance its protection of user credentials and sensitive information.
