Energy efficient processing of location based query in Wireless Sensor Networks

These wireless ad hoc sensor networks (WSNs) have received considerable academia research attention at present. The main purpose of a sensor network is information gathering and delivery. Therefore, the quantity and quality of the data delivered to the end-user is very important. The energy-constrained sensor nodes in WSNs operate on limited batteries, so it is a very important issue to use energy efficiently and reduce power consumption. To maximize the network lifetime, it is essential to prolong each individual node¿s lifetime through minimizing the transmission energy consumption. In this paper, we introduce a two-phase decentralized adaptation (TPDA) algorithm through in-network query processing, that is intended to provide a reliable transmission environment with low energy consumption. Simulation results show that this scheme outperforms the existing schemes even in the presence of high node density and overcomes simultaneous packet forwarding.
