Construction method of secure tunnels in wireless Ad-Hoc Networks

In Ad-Hoc networks, the transmission data of some secure nodes has the security risk of being monitored by ordinary nodes. Building some encrypted secure tunnels between secure areas is an effective way to ensure transmission security. We mainly study some efficient methods for constructing secure tunnels. First of all, two basic principles of tunnel construction are proposed concerning locations and number of tunnels. Then, four methods of minimizing tunnel construction are designed for different network objects (tunnel links, secure areas, secure nodes and secure traffic) with different network parameter requirements. Finally, the main performance indicators are the suggestions analyzed through experiments, and the suggestions for tunnel construction in different network environments are also proposed.
