QoS routing in MANET through cross-layer design with BER and modifying AODV
Ram S. Dahal, Teerapat Sanguankotchakorn · 2011
Many shortest path routing protocols have been proposed neglecting the effect of lower layers. Here, the Modified Ad-hoc On Demand Distance Vector routing based on Bit Error Rate (MAODV-BER) is proposed, where the route discovery of AODV has been modified to achieve the stable route by obtaining Bit Error Rate (BER) information from physical layer through cross-layer approach. Due to the use of multimedia applications in Mobile Ad-hoc Networks (MANET) strict Quality of Service (QoS) is required. So, for QoS fulfillment, the bandwidth and delay requirements are added in each route message. Finally, the path having minimum BER as well as minimum hop count and fulfilling QoS requirements is selected.
