Network Layer Protocol Research in Space Capsule Wireless Data Network Based on UWB

The wireless data transmission network in space capsule is gradually becoming important with the development of communication and aerospace technology. Ad hoc network and Ultra Wideband (UWB) are the current hotspots in the wireless communication. However, relevant research on data network is not enough and the system model of network is not quite complete or mature. In this paper, a wireless data transmission network is built based on the application background and structural characteristics of satellite space capsule. The inherent advantages of UWB can improve the performance of Ad hoc network. Considering some factors, this paper uses AODV of Ad Hoc network as network layer protocol because it possesses stable character and satisfies the specific background expectation. Then the network system is analyzed by OPNET simulation software under specific conditions. Through analysis of the simulation result, it proved that the wireless network system in satellite capsule possesses a stable system performance.
