Performance Analysis Of Queue Congestion Status Routing Protocol (QCS-AODV) For Ad Hoc Networks

Routing is a critical issue in a Mobile Ad-hoc Network (MANET). The most famous MANET routing protocols are AODV, DSDV, DSR and AOMDV. In this paper, an enhanced Queue Congestion Status AODV (QCS-AODV) routing protocol is introduced. In this protocol, beside the hop count, the congestion status at the nodes is used to select a free congestion path. Toward this, we introduce a new queue management scheme suitable for mobile ad hoc networks. This scheme, called an enhanced Partitioned Queue Management (PQM), utilizes both a packet type and number of hops for the arrival packets queuing policy. The congestion at each node is calculated using the proposed PQM scheme which used as metric in a path selection during the QCS-AODV routing protocol operations. The performance of the proposed routing protocol and PQM scheme are evaluated through a simulation based on small IEEE 802.11 ad hoc networks. The experimental results conducted using NS2 simulator reveals that the proposed protocol outperforms the AODV routing protocol.
