Abstract

In a remote sensor application it is desirable that the lifetime of the nodes be increased. This work proposes a modification to directed diffusion protocol, a data-centric protocol for low energy wireless sensor network. The main motivation behind is to balance the energy consumption among the sensor nodes to avoid early depletion of the network. Using a deterministic criteria our protocol selects the paths that have the higher relation of nodes energy reserves and distance to the destination. Simulation-based studies have been used to quantify the performance gains of our algorithm.
