Research On Wireless Ad Hoc Network Performance Based On Protected Area

The intrinsic characteristics of wireless ad hoc networks, such as multi-hop, self-organizing and self-adaptation, make this kind of network widely used in many fields, many research institutions and scholars at home and abroad have done a lot of its exploration and research. With the development of the communications industry technology, the future of wireless ad hoc network will be further utilized, from the military gradually into civilian areas. Besides, wireless ad hoc networks do not rely on large fixed infrastructure make it has a more extensive application scenarios, such as the remote mountainous areas that we can not reach, the place prone to natural disaster and so on.Some research about the characteristics of wireless ad hoc networks is particularly important, including the capacity of wireless ad hoc networks, the relay service, mobility of nodes, network topology and so forth.This paper first introduces the historical development of wireless ad hoc networks, describes the current popular different types of wireless networks, detailed analysis of the main technical characteristics of wireless ad hoc networks. And then introduced an analytical model of wireless ad hoc networks capacity to analyze the relay service, hybrid wireless network, wireless ad hoc networks under ultra wide band technology and summarizes the current increase network performance theory and method.Finally, a method of setting protected area in wireless ad hoc networks is proposed to improve the performance of wireless ad hoc networks, through rigorous theoretical proof and mathematical derivation to calculate the optimal protection radius. Theoretical analysis and simulation results show that a reasonable set of protected areas can effectively improve network performance.
