Sensor network is a novel technology about acquiring and processing information. This paper introduces the basic interaction patterns between requesters and providers of services during a typical Service Discovery task. It discusses existing service ...

Mobile grid provides mobile devices with a high reliability, performance and cost-efficiency. Physical limitations of the mobile devices make necessary the adaptation of the services that mobile grid can provide to the mobile devices. In the paper, we ...

Wireless location methods in sensor network have received significant attention in recent years. In this paper, we present a data fusion architecture and explore a Fuzzy Optimization data fusion (FODF). Simulation results show that the overall accuracy ...

In wireless sensor network, in-network data aggregation can eliminate redundancy, improve data accuracy and thus prolong the lifetime of network. However, most of data aggregation technologies assumed that the aggregator node has been receiving all the ...
