Minimizing congestion and improved QoS of AODV using clustering in mobile ad hoc network

With the increase in traffic in the network congestion increases, congestion unawareness in mobile ad hoc networks (MANETs) may lead to long delay, high overhead and packet loss which decreases the performance of ad hoc network. Many routing protocols are not congestion aware and this becomes the main design requirement of the routing protocol, which will tackle the problem of congestion and energy usage. This paper proposes an enhancement to the AODV routing protocol that consists of a cluster-based mechanism for supporting congestion control in MANET which provides a QoS aware path. The main feature of this approach is clustering and the selection of the cluster - head is on the basis of the congestion status of the nodes. This protocol is highly efficient in dealing congestion by achieving QoS constraints (good packet delivery ratio, low delay and reduces packet drop) with energy efficiency.
