Design of an energy-saving routing protocol in wireless sensor networks

This paper takes energy-saving into consideration, basing on typical clustering routing protocol and combining with the optimal cluster-head selection formula, the improved threshold formula and cluster radios formulas to choose cluster-heads. Applying the proportionality principle to the forming stage of cluster to make the distribution of cluster even more reasonable; during the stable stage of cluster, the member nodes in cluster use TDMA to communicate with the cluster-head node, and cluster-head nodes communicate with base station BS via multi-hop interrupt communication manner.
