Abstract :
As nodes in wireless sensor networks are usually supplied by a simple non rechargeable battery, the energy available in these nodes is very limited. Moreover, this limited energy is mostly consumed in transmission and reception of data. As transmission and reception is highly affected by routing algorithms, designing a proper routing algorithm will prolong the network lifetime. In this paper we proposed a novel routing algorithm, called locality-aware diffusion (LAD) that leverages spatial locality of sensed data in sensor networks to reduce energy consumption and prolong the network lifetime. The proposed algorithm is an extension to shortest path tree which is a common approach in routing algorithms. Simulation results show the validity and effectiveness of the proposed algorithm.
