Design of an Energy - saving Routing Protocol in Wireless Sensor Networks

This paper takes energy-saving into consideration, bases on typical clustering routing protocol,combines 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 more even and 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.
