In this paper, I propose a cloud wisdom education platform based on framework theory of SOA and cloud computing, with the purposes of solving serious information island and low teaching resource utilization, etc. These problems generally are caused by a great difference of educational informationization between regions and infrastructure configuration of hardware and software. In addition, educational expansibility and scalability can be realized based on all service resources in cloud computing, combination of SOA, and system development, instead of system integration.

In this paper, we present an approach to clustering sensor nodes based on a quantum Artificial Bee Colony (QABC). The ultimate goal is to converge to a better protocol that allows optimal energy consumption. In the proposed approach, some quantum computing principles have been used to represent each individual in the population in terms of quantum bits and to foster the search capabilities of the search process through an interference operation. The effectiveness of the proposed method has been assessed and compared to state of the art clustering-based methods namely Low Energy Adaptive Clustering Hierarchy algorithm (LEACH) and another Adaptive Artificial Bee Colony algorithm. The obtained results show that the proposed approach optimizes, in an efficient manner, the lifetime of wireless sensor networks. They also show that the proposed method competes with and even outperforms the other methods.

Wireless sensor Networks (WSNs) have become the ideal candidate to provide effective and economically viable solutions for a large variety of applications ranging from health monitoring, scientific data collection, environmental monitoring to military operations. In this paper, we present a proof-of-concept WSN to collect soil moisture content, which is one of the most fundamental data required for precision agriculture. Leveraging existing off-the-shelf hardware (MicaZ motes, MDA300CA data acquisition board, and EC-5 soil moisture sensors), the dominant open source embedded operating systems software (TinyOS 2.1.1), and MViz, we have built a prototype WSN to collect soil moisture. We present the detailed design and implementation of MDA300CA driver for TinyOS 2.1.1. Note that our architecture is general, so it is easy to integrate the driver of other sensor probes, thus collecting more types of data for different research purposes. Limited battery supply is a major concern when utilizing WSNs to build realistic applications. Therefore, we utilize solar panels and rechargeable battery to address this challenging problem. We illustrate our detailed design to package WSN nodes for outdoor development and present collected data to validate our design. Specifically, using sand soils with different water content, we demonstrate the result of our system. With enough details for researchers to understand and thus improve our design, our system could be a good starting point for their own research.

This papers deals with the implementation of neural network controlled distributed Active Filters. distributed Active Filters introduces the concept of installing multiple active filters at different locations. Shunt active filters consists of three phase VSI and an energy source connected at DC side. Synchronous Reference Frame theory is employed for enhancement of power quality. A comparison and analysis of harmonic content of source current is done by using PI controller and Neural Network control. The new concept of proposed distributed Active Filters are simulated using MATLAB power system Toolbox.

Monitoring of the sub-sea environment requires advanced sensor networks with both stationary and mobile nodes on the surface and underwater, each node playing a different role. The combination of mobile and stationary nodes, the loss of nodes due to harsh conditions, the difficult conditions for wireless sub-sea communication and the need for nodes to collaborate are all factors that require new approaches to software architectures for such nodes and systems. This articles presents work in progress that sets out to address these issues by adapting approaches from software engineering solutions to ubiquitous computing.

Cloud computing is widely being adopted by many companies because it allows to maximize the utilization of resources. However, the complexity of cloud computingsystems with the existence of many cloud providers makes infeasible for the end user the optimal or near-optimal resource provisioning and utilization, especially in presence of uncertainty of very dynamic and unpredictable environment. Hence, adaptive load balancing algorithms are a fundamental part of the research in cloud computing. We formulate the problem and propose an adaptive load balancing algorithm for distributed computer environments. We also discuss the energy efficiency of our solution for the domain of VoIP computations on federated clouds.

In a wireless body area sensor network (WBAN), biosensors are implanted or worn on an individual to acquire medical data for a clinical diagnosis or physical monitoring. Traditionally, authentication and cryptography techniques are used to achieve the data confidentiality and privacy of a WBAN system. However, for WBAN systems, besides data itself, the pattern of data transmission may leak critical information about the user. For example, various medical sensors deliver data in different patterns and these patterns leak many critical facts, e. g., what sensors are used (which implies diseases the individual may have), and how frequent the sensor is sampling (which implies how urgent some abnormal observation is about a patient). In this work, to address this challenge, we design a regulator, which packs real data session into a type-independent transmission model at transmission layer. All valid data packets are equably sent at the frequency defined by the regulator and at the same length to clutter the inherent pace of valid data transmission and other parameters. We also propose a strategy PAS to minimize the overhead while preventing attackers from locating the patients. Our extensive experiments validate our regulator and PAS design.
