An Energy Aware Data-Centric Routing Algorithm for WSNs with High Energy Efficiency

Article Preview

Abstract:

In WSNs, energy efficiency is one of the most important factors to influence its performance, and well designed routing algorithm can obviously improve the energy efficiency. Because data-centric routing algorithm is easy to be deployed and has more robust in application, many new algorithms are proposed based on this type. In this paper, some typical existing routing algorithms are analyzed, and the characters of these algorithms are introduced. According to these analyses an energy aware data-centric routing algorithm named EADC is proposed. In EADC, the nodes residual energy is considered when transmitting route is selected. And to ensure nodes energy information acute, a special package head and a link storing neighbor nodes are defined to update nodes energy information when transmitting message. Through these designs, the route can be dynamic adjusted to make the energy consumption more reasonable. At last, EADC is compared with other typical routing algorithms in a series of experiments, and the experiments result proves that EADC has obviously improved the WSNs energy efficiency.
