In Wireless Sensor Networks (WSNs), sensor nodes are resources constrained, such as limited energy, limited processing capability and limited memory. Since the nodes in WSN are typically very small size and are powered by irreplaceable battery, efficient use of energy becomes one of the most challenging tasks. In this paper, energy-aware routing scheme is proposed based on data-centric approach, directed diffusion. Directed diffusion is a data centric routing protocol in wireless sensor network. In the proposed system, the route is determined depending on the remaining energy. Routing procedure is to get a route for data transmission from source to sink based on the route designed by the proposed system.
