A cross layered routing protocol for ad hoc networks

摘要

In this paper, we investigate a cross layer design for routing in mobile ad hoc networks. The goal is to improve the performance of the existing Ad-hoc On Demand Distance Vector (AODV) routing protocol. The design allows the physical layer sharing the received signal strength (RSS), and the medium access control (MAC) layer sharing the remaining energy, as well as the remaining queue length information with the network layer. Based on this information, the network layer computes a weight value that forms the routing metric used for route selection in the enhanced protocol. Finally, we implemented Turbo-AODV (TAODV) which is a modified version of the well-known AODV. Simulation results demonstrated superior Quality of Service (QoS) and better performance comparing to AODV in terms of packet delivery, normalized routing load, discarded packets on queues, and routing overhead.
