A Topology-Aware Routing Protocol for the MANET with Multiple Sinks

In this paper, a topology-aware routing protocol is developed for the mobile ad-hoc networks (MANET) with multiple fixed base stations (BSs). The protocol aims at delivering packets reliably from the source node to its nearest BS. A topology-aware route recovery method is proposed to resolve route failures, and a novel "majority vote" algorithm is developed to locally update the information about the nearest BS. In addition, as a backup solution to the periodic advertisement, we propose an "on-demand" topology refreshing algorithm, timely updating the network topology at the request of the urgent source nodes. Simulation results are provided to illustrate the effectiveness of the proposed protocol
