Research Of UWB Wireless Network And Its MAC Protocal Based On Mobile Ad Hoc

With the development of international economy, the consumers need a wireless network to implement a flexible communication in many fields besides traditional wire network nowadays. In this background wireless communication technology get a rapid development. UWB and Ad Hoc, due to its excellent performance, are just the two technologies been widely applied in wireless communications.Ad Hoc is a bran-new network technique with lots of characteristic. The topology of network changed frequently since nodes of Ad Hoc network were locomotive. Ad Hoc networks had these advantages: Quickly and flexibly to build the network ,Hard to destroy , A cheap price, etc. it had a very extensive use in military affairs , rush to deal with an emergency and the electronic classroom.UWB is a base band transmission technology based on impulse radio. The main advantages of UWB wireless communications were described in such words as higher bit rate, lower power spectral densities, exceptional multi-path immunity, simple structure and low probability of detection. Now UWB was wide applied in military and civil applications because its advantages.The UWB wireless network based on Ad Hoc got the advantages of UWB and Ad Hoc, it took Ad Hoc to build the network, and in the same time UWB was used as a transmission technique to get the Advantages of UWB. For example, UWB could get a very high data transmission speed in the short distance. We can assume that: UWB wireless communication network structured by Ad Hoc has an extensive perspective of application, and it will become an important part of future wireless ubiquitous network.The thesis gave an overall introduction to UWB network with Ad Hoc networking technology, including the typical application scenarios, network architectures and hierarchical protocol stack; discusses the hinge...
