Enhancement of QoS in MANET using semi graph model and AODV routing protocol

Abstract

Improving the Quality of Service (QOS) in the network is a major subject to be discussed in development of MANET. Current researches are performed to generate congestion control measures to schedule the data packets from different network paths to process at the specific node. The performance of that specific node should be increased based on the capacity of routing the packets into multiple paths of the network. The performance of these mobile intermediate nodes are been improved by combining the network layer and transport layer approaches. Due to the MAC layer problems like congestion increases the packet drop, delay and error rate, decreases the delivery rate and throughput of the network. Frequent disconnection of nodes is also possible due to the mobile nature of the nodes in MANET. In order to overcome these limitations, a maximum dominant set based semi graph model is developed to frame transport layer mechanism and AODV. DSR protocols are involved to generate a routing path between the nodes of the network. The performance of the semi graph model along with the AODV and DSR routing protocols were evaluated by implementing in the hardware environment.
