Abstract

A hybrid ad-hoc cellular network (HACN) is based on the idea of replacing the stationary cellular base stations with mobile routers. Communications among the mobile routers is achieved using satellite links or high bandwidth wireless channels. In this chapter, we present and evaluate efficient recovery and routing protocols for mobile routers in HACN. In the dual backup recovery protocol, a standby router is mapped (dedicated) to each primary router. A more flexible protocol, called the distributed recovery protocol, is obtained by relaxing this one to one mapping and scattering the backup routers geographically among the primary routers. The effectiveness of the distributed recovery protocol is demonstrated by simulation results. A simple analytical model is also presented for computing the blocking probability of new calls in the presence of router failures. The chapter is concluded by presenting an efficient location-based routing protocol for HACN mobile routers. Performance results of the routing protocol are presented.
