Study on Routing Protocol in Airborne-Sea Ad Hoc Networks with Directional Antennas

Abstract

In this paper, we propose a directional routing protocol for airborne-sea ad hoc networks (ASNETs). Directional antennas have the potential to provide a fundamental breakthrough in ad hoc network capacity, connectivity, and covertness because they have great advantages such as high spatial reuse and range extension. ASNETs is a special ad hoc network which include two kinds nodes, namely aircraft and ship. To fully exploit the benefits of directional antennas in ASNETs, a Node-Avoided Directional Routing (NADR) protocol is to be considered. The main feature of NADR is that route request packets is always transmitted by those less load nodes. That is why NADR can effectively balance the load of node. Preliminary simulation results are found to be very promising, the performance of NADR is better than DSR and DRP in terms of the packet delivery ratio and throughput.
