Analysis And Design Energy-efficient Routing Protocol For Wireless Sensor Network

Energy conservation is a very important issue in wireless sensor network. There is insufficient use the information which the node gathered in traditional routing protocols for wireless sensor network. Therefore, when these protocols were developed, nodes are the main idea. The idea makes routing and data transmission separated. Through research and analysis classical routing protocols for wireless sensor network, we found that when we develop a new protocol, if we can make the data as a main idea, we can unify the routing process and data sending process. Then many of the established process of routing are reduced. If this idea is realized, reducing energy consuming and improving the life of wireless sensor network will come.In this paper, classical WSN routing protocols are analyzed in detail. For instance, directional diffussion protocol and LEACH protocol. By simulation, all conclusions are verified and we can get disadvantages of classic WSN routing protocols in saving energy also. For example, it is so complicated for forming paths or there is no effective strategy of controlling nodes for sending data. One reason is: Forming route and sending data work separately. Further more, in this paper, the feasibility of technology of RISSI using in routing protocols is discussed. The right of sending and decision need be separated in this technology In this paper, with information redundancy in WSN ,RSSI is merged into routing protocols and form one kind of new fuel-efficient routing protocol .Based on prepared routing algorithm, simulation of classic fuel-efficient routing protocols and LEACH protocol is achieved respectively on NS platform. In addition, by comparison between life and unit receives data amount, I find out new routing protocol is better than classic fuel- efficient routing protocols both in life and unit receives data amount when load of network is up to 40 percent.
