Abstract

On-demand routing schemes suffer from the initial route setup latency, introduced by their discovery phase. This degrades the performance of interactive and/or multimedia applications. Table-driven routing, on the other hand, responds more quickly to call/route requests, but it wastes a large portion of the scarce wireless bandwidth on routing table broadcasts. Structured routing can be utilized to reduce the route setup time and increase throughput. In our Virtual Base Stations (VBS) architecture, a mobile node is elected from a set of nominees to act as a mobile base station within its zone. Based on our VBS routing protocol, a mobile station that wishes to send a packet to another mobile node in the network sends the packet to its VBS, which forwards it to the proper next hop. In this chapter, we also propose a novel routing scheme based on the VBS architecture, namely, the Virtual Base Stations Proactive-Reactive (VBSPR) routing protocol. VBS-PR promises to achieve considerable gains in terms of increasing the capacity of the wireless ad hoc network, reducing the call setup times and end-to-end delays and increasing the routing efficiency. VBS-PR can operate as a purely on-demand scheme and utilize the wireless mobile infrastructure to increase efficiency.
