PASSIVE BANDWIDTH ESTIMATION ENABLED ROUTING PROTOCOL FOR MOBILE AD HOC NETWORK
Rajeev Kumar, Prabhudev Jagadeesh · International Journal of Engineering Applied Sciences and Technology · 2019
Mobile Ad hoc network (Manet) is a collection of movable wireless mobile hosts.Manet does not have any fixed infrastructure.The real time Applications like video conferencing and web casting require quality of service (QoS) support.In recent years most of the QoS routing protocol have been implemented to provide bandwidth aware QoS routing.But these protocols cannot estimate bandwidth accurately due to fading and shadowing effects and variation in the existing traffic generated by neighbor nodes.Therefore this issue is open in the research field of Manet.IEEE 802.11 does not perform well in terms of throughput and delay when the traffic load increases.Admission control is needed in order to support real time application.Supporting QoS in IEEE 802.11 based ad hoc network needs available bandwidth for a route from source to destination.To reserve bandwidth for QoS routing, local bandwidth at each node should be determined.In this paper a new BWA (bandwidth aware) technique is proposed and incorporated in AODV.The BWA-AODV protocol provides better QoS routing in terms of bandwidth, packet delivery ratio end to end delay, and energy consumption compared to AODV and DSR protocol.
