Energy Consumption Improvement Of Traditional Clustering Method In Wireless Sensor Network

Tóm tắt:

In the traditional clustering routing protocol of wireless sensor network, LEACH protocol (Low Energy Adaptive Clustering Hierarchy) is considered to have many outstanding advantages in the implementation of the hierarchy according to low energy adaptive cluster to collect and distribute the data to the base station. The main objective of LEACH is: To prolong life time of the network, reduce the energy consumption by each node, using the data concentration to reduce bulletins in the network. However, in the case of large network, the distance from the nodes to the base station is very different. Therefore, the energy consumption when becoming the host node is very different but LEACH is not based on the remaining energy to choose the host node, which is based on the number of times to become the host node in the previous rounds. This makes the nodes far away from the base station lose power sooner. In this paper, we give a new routing protocol based on the LEACH protocol in order to improve operating time of sensor network by considering energy issues and distance in selecting the cluster-head (CH), at that time the nodes with high energy and near the base station (BS) will have a greater probability of becoming the cluster-head than the those in far and with lower energy.
