Research On The Low Interference Of Multipath Routing For Wireless Sensor Network

Wireless sensor network, which is made by the convergence of sensor, embedded computing, distributed information processing and wireless communication technologies, is a new information acquisition, processing and transmission technologies. It can be used in military, environmental monitoring, medical and commercial, etc. It has a wide application future. In a word, it will be one of the most useful technology for the 21th century. Due to WSNs'specialty such as high density and energy limited of nodes, the existing wireless routing protocols are not fully applicable to WSN, so the design and improvement of the existing routing protocols has become a research hotspot.Based on the overview of wireless sensor network, we investigate and analyze the interference of route protocol for the multipath Routing of the wireless sensor network. To begin with, we gave a summary of the history of Wireless Sensor Network. And we introduce the main work and arrangement of the article. Then, we have an overview of structure of the wireless sensor network. And we analyze the feature and the technical difficulties and challenges that we had to face in the future of wireless sensor network. At the same time, we gave the classification of the routing protocols for Wireless Sensor Network. And we had listed and made comparison of several kinds of existing protocols. In this paper, we focus on the route coupling and interfere for the multipath routing protocol of Wireless Sensor Network. We point out that the route coupling in wireless medium often occurs when some routes which have disjoint node are located physically close enough to interfere with each other during data communication. So we look on the interference of the zone-disjoint nodes which own to the different path in the network as one of the important gene, and then we use the directional antenna in place of the omni-directional antenna. From the result of simulations, We improved the performance of the New protocol through some adaptation on the algorithm. Finally, the main work of the thesis is concluded and the problems that need to study in future is pointed out.
