Clustering Routing Protocol And Algorithem Research Of Wireless Sensor Network

Wireless sensor network is the synthesis of micro mechanical system, sensor technical, embedded computer technical, modern wireless network communication technical and contributed signal processing technical, etc, which can be vastly used in military and commercial areas. However, compared with traditional computer network, wireless sensor network's source is limited, and the computing power, storage capacity and power of network nodes are severely limited, and the power limit can limit the running period of wireless sensor network directly. So the design of how to prolong the network lifetime effectively is the key problem of wireless sensor network. Based on the feature of wireless sensor network, the paper does some research on clumping routing protocol and algorithm and proving and analyze them by simulation. The main researches are as follows:(1)Describe the current situation and meaning of wireless sensor network research. The structural frame, characteristics, key technology and application of wireless sensor network research are introduced in details.(2)Introduce the some requirements of MAC protocol design in wireless sensor network research, and classify the existing MAC protocols by competition and fixed allocation principle. Several typical MAC protocols are key research, such as S-MAC protocol, T-MAC protocol and DEANA protocol. Working process and advantage and shortcoming of these MAC protocols are analyzed in details.(3)Wireless sensor network research routing protocol research:routing protocol of wireless sensor network research is different from traditional routing protocol of wireless self-organization network in design requirement and performance index. Start with the characteristics and design requirement of wireless sensor network research routing protocol to analyze the existing routing protocol, classify the typical routing protocols by different standards, and study working process and advantage and shortcoming of these MAC protocols.(4)LEACH protocol is a kind of low-power self-adaption hierarchy routing protocol for wireless sensor network, which can prolong the network lifetime. Aiming at the problem of clustering and communication process, a kind of improved clumping routing algorithm based on LEACH protocol is proposed, which can optimize the selection of cluster head and communication mechanism between cluster head and Sink. Compared with traditional LEACH protocol by simulating in Matlab, the improved protocol is better for balancing network power and prolonging network lifetime. The paper also introduces two more algorithms of LEACH protocol improvement, describes the advantage, shortcoming and comparison the end.
