An Improved Routing Protocol for Directed Diffusion in Wireless Sensor Networks

Abstract

Wireless Sensor Networks consist of a lot of sensor nodes that have sensing, communication capabilities. The sensor nodes are usually the electronic components with low-cost, low power, low transmission ability. In this paper, we consider the application-aware network environment and utilize the hop-count and remaining energy to select the transmission path. In addition, this paper adopts two routing paths for the urgent event to promote the successful rate of the data transmission. Basically, our mechanisms could eliminate many unnecessary transmission packets, reduce the burden for the network, and extend the life time of the network.
