Abstract

Emerging network systems require specific medium access layer and routing protocols to be suitable in a high speed environment. We present modified 802.11 MAC and OLSR protocols for medium access and multihop routing in highly dynamic ad-hoc networks. Modified 802.11 algorithms use power and smart antenna management. A modified OLSR protocol uses node location, speed and trajectory analyses heuristics. The analysis of OPNET™ simulations shows that our proposed algorithms have several advantages over other MANET protocols in terms of packet delivery ratio, delay and overhead.
