Research about improvement of LEACH protocol

This paper studied the typical clustering Routing Protocol-LEACH protocol, analysed its deficiencies and proposed improved ideas. N-LEACH protocol improved the election process of LEACH cluster head node while the remaining energy as the basis of election cluster head node,and increased the process of choosing root node in all the cluster head nodes. It was root node that collected data then sent them to the base station,which reduced the number of cluster head node who communicated to base station, increased the energy efficiency, extended wireless sensor networks´ lifetime.
