Analysis And Design Of Routerand Security Based On Wireless Mesh Network

Wireless Sensor Network syncretizes the technologies of sensor, information management and network communication. Wireless Sensor Network is a kind of build-up mode developed from the inspect function. By transmiting and controling the information through wireless network, it is due to apperceiving cooperation place, gather and deal with the information in the area of the network overlay and arousing the response of observer. It synthesizes the technologies of sensor, bed-calculate, distributed information processing and communications. Because of its large application value in environment detecting, industry controlling, military, agriculture breeding, medical treatment and outer space exploring, Wireless Sensor Network gets large attention by the government, army, MultiNational Corporation and scientific researching institution, and it is the key point of research.With the development of wireless network, Mesh network is appearing more and more. Anticipately it can resolve the restricting problems of Ad-hoc and advance its performance. Mesh network has many applications and its integrated with sensor network is an important aspect of its applications.This paper mainly to the following aspects:1. Survey and study the current application actuality of Ad-hoc and the method to actualize the router part and security management part. Evaluate the performance of the build-up flat.2. Make a deep study on NS2 which is a major network simulating software. Accomplish the design with it and study its design method also with simulating idea for the future. 3. Read the standard of Mesh network 802.11s which is brought forward by IEEE.4. Study and compare several main router protocols used in Mesh network.5. Survey and study the threshold of Shamir and DES encrypt arithmetic. Join them into the frame to actualize the security part of the 802.11s protocol.Wireless network's progress has led the mobile industry's direction, and it is satisfying and inspiring the people's request constantly. Wireless network which satisfies people's kinds of needs will be a new opportunity. So combining the router with the security and designing on actualized protocol flat has a great practicing and referential value.
