Energy Efficient Cluster Based Partial Multihop Algorithm for Hetrogeneous (CPMH) WSN

A Wireless Sensor Network (WSN) consists of spatially distributed autonomous sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants. In recent years, there has been a growing interest in wireless sensor networks. One of the major issues in wireless sensor network is developing an energy-efficient routing protocol. The challenge lies in efficiently providing acceptable accuracy while conforming to the many constraints of WSNs. Energy limited is one main bottle-neck for wireless sensor networks. Due to unreasonable cluster head electing and intensive energy consumption of cluster head in clustering algorithm, I propose cluster based partial multihop algorithm for heterogeneous WSN, Which aimed to optimize cluster head voting and balance energy consumption of cluster head. I also propose a hierarchical tree routing method that reduces the distance of cluster-head to the base station.
