Reliable and Efficient Multi rate Aware Proactive Routing Protocol for IEEE 802.11 based MANETs
Ahmed Khalid, Cheeha Kim · 한국통신학회 학술대회논문집 · 2015
Most existing mobile ad hoc network (MANET) routing protocols use the minimum number of hops as a routing metric. These paths tend to contain long range links that may lower both throughput and reliability. Higher throughput can be achieved by using short but effective links. A few protocols have been proposed to address this issue. The main problem with these protocols is that they use receiver signal strength indicator (RSSI) value to assess the link states. In realistic networks, RSSI value is not always accurate and hence using it can result in inaccurate decisions which will degrade the reliability of paths. We propose a reliable and efficient multi-rate aware proactive (REMAP) routing protocol for MANETs. REMAP does not make routing decisions based on RSSI value and hence provides more reliable paths. REMAP also decreases the overhead caused by periodic hello messages in other protocols. Simulation results show that our proposed protocol can approximately increase the throughput by 300 %, decrease the network delay by 250 % and overhead by 150 %.
