Research On The Multipath Routing Algorithm In WSN Using Traffic Prediction

Wireless sensor network(WSN) is a wireless network which composed of in a special method ,the target of WSN is to cooperative sense,collect and process the information of sense object in a network coverage area, then send to the observer,wireless sensor network get together with Utility Computing ,plastic electronics and bionics is considered as four high-tech industries in the future around the world .Routing algorithm is the key for wireless sensor network to transmit data in self-organization manner, Therefor the research on routing mechanism of wireless sensor network has important academic significance and realistic value.This article make use of time series analysis and traffic prediction theory to dynamic analysis the network traffic of wireless sensor network in real time.Then apply these method to the routing mechanism of wireless sensor network, we also compare the new method with traditional method, and we have obtained some significant research achievement. The main work are as follow :1. At first this article summarize and analysis the routing mechanism of wireless sensor network in existence,and then describe the advantage and disadvantage of existing routing mechanism of wireless sensor network. Then the article summarize the traffic characteristic of existing traditional network, and analysis the existing network traffic prediction model and it's advantage and disadvantage.2. Basing on to summarize and analysis the traffic characteristic of wireless sensor network, the article combined the traffic characteristic of wireless sensor network with ARMA model and present a new real time on-line traffic prediction model for the network traffic of wireless sensor network., and realize in the simulation platform, we also validate the efficiency of the prediction model through the contrast and analysis the simulation result.3. The article combined multipath routing algorithm of wireless sensor network with traffic prediction algorithm and present a switch mechanism of multipath routing of wireless sensor network based on traffic prediction, the article make simulation verification using the simulation platform of NS2.26 and it shows that the new...
