IP communication architecture and overhead performance of heterogeneous tactical wireless network for air platforms

The heterogeneous tactical wireless network for air platforms is an Internet system constituted by several heterogeneous wireless data links.Internet Protocol(IP) can connect different types of network well.This paper proposes a communication architecture of heterogeneous tactical wireless network for air platforms based on IP technology and discusses the issues about address assignment scheme,routing method and data encapsulation protocol.According to the characteristic of tactical wireless network,it analyzes the relationship between end-to-end communication protocol stacks as well as the protocol adapting scheme for different types of network.Air platforms can be assigned IP address statically or dynamically.The routing frame and the scheme of destination address seeking for heterogeneous tactical wireless network routing is developed.The encapsulation protocols of IP message are analyzed.Simulation for the overhead of different encapsulation protocol shows the better overhead performance of the packaging mode based on generic framing procedure(GFP).
