RC-LEACH Protocol Region Based Optimization Algorithm

Wireless Sensor network (WSN, Wireless Sensor Networks), the traditional Wireless network one of the important supplement, attracted the attention of a large number of research team, in recent years in the military, agriculture, environmental protection, medical, industrial, and other neighborhood play an irreplaceable role. But due to the energy of sensor nodes in the WSN are provided by the limited battery energy, most of the battery is placed in the environment of the unattended poor, difficult to change. So, in the design of routing protocols need to be considered to lower the energy consumption of sensor nodes as far as possible, so as to make the entire network to extend the life cycle.In order to solve the problem of network life, clustering algorithm is introduced, the entire network area is divided into several small areas, we call every small area for the cluster. Among them, the most classical clustering algorithm is LEACH protocol clustering algorithm, this article is in view of the algorithm to improve research and put forward a kind of RC-LEACH (Route Cluster-LEACH) protocol optimization algorithm based on region. Specific design scheme is divided into several small area to the entire network area, each area shall be carried out in accordance with the LEACH protocol cluster head election and transmission, the cluster head node in each area will be information to their own place within the cluster of cluster heads, again USES the greedy algorithm for cluster head of communication between the path algorithm, namely through multiple hops between cluster head, cluster header information to the base station. And through simulation experiment, proves that the algorithm is compared with the LEACH algorithm, in the entire network zoning area, in each new area to select cluster head in proportion method can make the distribution of cluster in the network is more uniform and the member communication between nodes and cluster heads and base station consume less energy, prolong the network lifetime. Cluster more jump between data and information transmission way compared with the LEACH protocol is also greatly save the energy of each sensor node, at the same time the corresponding verification all the sensor nodes in the network the remaining energy in each round LEACH protocol is improved.
