Distributed Routing for Wireless Sensor Networks Based on Cluster Maintenance

Saving energy is an important goal in designing of wireless sensor networks, and routing algorithm has an important impact on energy consumption for wireless sensor networks. Therefore, improving the energy efficiency of routing algorithm to reduce energy consumption in the network is very necessary. This paper proposes a new distributed routing algorithm based on cluster maintenance (CMDR-LD). By prolonging the steady-state phase time and retaining the concept of round in routing algorithm, the new algorithm achieves the purpose of saving energy ultimately. Simulation results validate the energy efficiency of that algorithm.
