The Research Of Energyefficiency Routing Algorithm Baled On Wireless Sensor Network

In recent years Internet of Things developed very fast, and the Wireless Sensor Network is the core technology of the network. As the basic network of getting and transmitting information, it can be placed in complex physical environment, such as natural disaster area, battle field and other dangerous areas. It is also be set in the places which people can’t access to, such as the plane interior, the machine interior and so on. Wireless Sensor Network can perceive and accumulate amount of data and information, and distributed process them. Thus the precision of sensational data is improved. In this way it can provide people rich and multi-dimensional environment information.The WSN node has limited power and the power supply only relies on battery. At the same time, the node power supply is hard to be changed. So WSN node energy saving problem became a key problem in the study. In this article the energy efficiency routing algorithm of wireless sensor network got in-depth analysis, many kinds of energy saving routing algorithm has been classified and sorted. Two efficiency better energy saving routing algorithms N_LEACH and NEEC have been presented through contrasting the advantages and disadvantages of performance among some typical energy efficiency routing algorithms. And comparison and analysis of energy consumption and the number of live nodes are made for these two new algorithms.This paper has a deeper analysis of energy saving routing algorithm of wireless sensor network. And this article combined with some characteristics of the wireless sensor network and improved one of these algorithms towards to the disadvantage of several energy-efficiency routing protocols. So the algorithm N_LEACH is presented. Some ideas of the existing algorithm are considered and another algorithm with better efficiency named NEEC (New Energy-efficient Clustering Wireless Sensor network protocol) is proposed according to some other routing algorithm. At the end of the paper, the two new algorithms were validated by experiment through NS2experimental platform and detailed comparison chart were provided. The two algorithms have significantly improved efficiency than traditional algorithms, and they prolong the life of the network and reduce energy consumption of the network.
