Abstract

To balance energy consumption for nodes is an important factor considered in wireless sensor networks (WSN). In the paper, we research a heterogeneous wireless sensor networks with two different type sensors which have different initial energy as well as have different length data message to transmit. Each sensor node in such a network is systematically gathering and transmission sensed data to a base station for further processing. We develop and analyze the protocol based on residual energy and energy consumption rate (REECR), which is an energy efficient routing protocol we proposed previously for heterogeneous wireless sensor networks. Although REECR protocol is more energy efficient than Low-Energy Adaptive Clustering Hierarchy (LEACH) protocol, it is not very ideal to balance the energy consumption of nodes, namely, from the first node dies to the last node dies, the time span is long. This paper proposed a zone-based REECR (ZREECR) routing protocol to balance the energy consumption of nodes in the networks, simulation results show that all nodes die from start to end become shorter, the balance of energy consumption between nodes is improved.
