Application-oriented routing in hybrid wireless networks
Yuan Sun, Elizabeth M. Belding‐Royer · 2004
Hybrid wireless networks are a viable networking solution to combat the limitations of infrastructured wireless networks and provide Internet connectivity to ad hoc networks. This paper first analyzes the requirements for deployment of hybrid networks in different application scenarios. Then two routing schemes designed for different traffic patterns in hybrid networks are proposed to achieve optimal performance. Simulation results show that with a large percentage of short web-based traffic sessions, using a gateway as a default router results in better performance with lower latency, fewer routing table entries, and manageable control overhead. When traffic locality is high and Internet traffic is only an occasional occurrence, the reactive routing scheme results in better performance, yielding low control overhead and higher throughput.
