Analysis and research of improved LEACH routing protocol for pressure sensor based on WSN

摘要

This paper focused on the energy model and algorithm description of LEACH routing protocol. By analyzing inadequate and combining with the actual situation, proposed network model and assumptions for linear structure, the improved protocol-clustering link routing protocol LEACH-P that it based on LEACH and PEGASIS algorithm ideological, described the network model of LEACH-P protocol which is used in the coal face. This protocol first choose cluster head in the wireless sensor networks and make all nodes into clusters.Then it top-down traversals cluster head and finds a link connection which optimizes cluster head election and inter-cluster communication. NS2 simulation show that the improved protocol can extend the network life cycle and have a good real-time.
