Most of the wireless sensor networks consist of static sensors, which can be deployed in a wide environment for monitoring applications. While transmitting the data from source to static sink, the amount of energy consumption of the sensor node is high. It results in reduced lifetime of the network. Some of the WSN architectures have been proposed based on Mobile Elements. There is large number...

This paper presents an improved InGaP/GaAs heterojunction bipolar transistor (HBT) model based on the Vertical Bipolar Inter-Company (VBIC) model. New transport current expression is proposed by considering the heterojunction effect. Collector capacitance is developed due to the mobile charge modulation, and the transit time formula is improved to account for electron velocity variation with th...

The miniaturization of electronics and recent developments in biometric and screen technologies will permit a pervasive presence of embedded systems. This and the inclusion of networking capabilities and IP addresses in many handheld devices will foster the widespread deployment of personal mobile equipment. As mobile devices proliferate and their diversity grows, it is surprising to discover h...

Applications that require fast response time such as emergency preparedness and hostile environment surveillance pose challenging obstacles to wireless sensor network (WSN) protocols. A routing protocol must provide fast and reliable techniques for data propagation. Most routing solutions for WSNs utilize static sinks to collect data from the entire network. This approach results in high traffi...

Most sensornetworkarchitectures typically assume thatnodes are stationary after deployment. However, a number of recent papers have shown that theuseofmobilenodesormobiledata collectors (MDC)can significantly improve the performance of a network. In thismodel, the network can be viewed as a three-tier architecture, where the lowest-tier consists of a set of sensor nodes. Themiddle-tier contains...

The wireless sensor network is made up of collection dense sensor node where collection of data from the sensing fields becomes an issue. In the existing system a VELCT (Velocity Energy Efficient Link Aware Cluster Tree) is used to construct a DCT (Data collection Tree) to collect the data from the CH (Cluster Head) and then relay it to the BS (Base Station). But this system fails to balance th...

Now a days the “big data” emerged as a hot topic because of the tremendous growth of the Information and Communication Technology (ICT). The key contributors of the big data in the networks is the distributed Wireless Sensor Networks (WSNs). The data generated by an individual sensor node may not appear to be significant, the overall data generated across numerous sensors in the densely distrib...

The recent advances in the field of Ambient Intelligence (AmI) have raised a new generation of distributed applications with sophisticated characteristics. AmI applications are distributed among mobile devices interconnected by wireless communication media that allow them to interact spontaneously with other devices the environment forming mobile ad hoc networks. Although many distributed garba...

We have designed and implemented a new garbage collector for the Standard ML of New JerseySystem (SML/NJ). This collector has higher performance, lower latency and generally requires lessphysical memory than the existing SML/NJ collector. In addition, it is able to exploit the largesecondary caches found on modern workstations. This paper describes the design of the collector,an...
