Multi-criteria routing in pervasive environment with sensors

摘要

Interconnected computing nodes in pervasive systems demand efficient management to ensure longevity and effectiveness. This is particularly true when we consider wireless sensor networks, for which we propose a new scheme for adaptive route management. There have been numerous studies that have looked at the routing of data in sensor networks with the sole intention of reducing communication power. However there has been comparatively less prior art in the area of semantic and multi-criteria based routing. We look at routing in sensor networks from these perspectives and propose an adaptive multi-criteria routing protocol in the context of wireless sensor networks. Our experimental results show that our approach consistently outperforms the leading multi-criteria algorithm in its class that considers query semantics, in terms of network lifetime, network coverage and the survivability of critical nodes.
