Abstract
LEACH(Low Energy Adaptive Clustering Hierarchy) is a classical routing protocol for WSN which takes the adaptive clus-tering algorithm. All nodes will bear the energy consumption averagely, which can extend network lifetime in a manner. However, the cluster head of LEACH routing protocol is generated randomly, it doesn' t consider the node' s residual energy, also doesn' t achieve the most optimal cluster head-selection purpose. The cluster head of LEACH routing protocol communicates with the base station. If the distance is far between them, it will bring greater energy loss. This paper combines LEACH and some of the existing improved LEACH algorithm, then proposes a new routing protocol (Advance-Leach). It integrates the node's residual energy, location and the number of cluster head nodes, which takes strategy of hop and multi-hop combination between the cluster head and the base station. It effectively reduces energy consumption and ensures the network load balance. Simulation results show that some performances get effective im-provement for example the energy consumption of the protocol, data rate successfully received and so on. It extends the life cycles of nodes and network.关键词
