Cluster Based Distance Sequence Distance Vector Routing Protocols for Mobile Ad-hoc Network

Abstract

Mobile Ad-hoc Network is a self-organizing and self-configuring network that has mobile nodes connected wirelessly to each other. Transmission of data packets takes place through single or multi-hop in MANET. Each node in the MANET acts as a router and a host device. MANET is a scalable network and can accommodate nodes to a great extent. However, due to the increase in traffic, it may occur congestion in mobile ad-hoc network. Congestion is a major issue for end to end delay and network overhead. The clustering technique is used to virtually divide the MANET in groups, which allows the data to divide in groups as well. Clustering technique is more efficient than the existing standard protocols used for routing. Such fundamental (DSDV) protocol leads to routing overhead in scalable MANET. In this work, we presented a cluster-based technique for DSDV (Distance Sequence Distance Vector) routing protocol to overcome routing overhead, reduce the packet size and utilize the bandwidth in a large network. Three steps are defined for the cluster based on DSDV, which are the cluster head selection, cluster formation and routing of packets. The cluster based on DSDV (CDSDV) is a Clustering technique to overcome the production of excessive information. Since, the algorithms are made in a manner that the nodes are required to share routing information inside the cluster instead of the entire network. Hence, the results of the CDSDV demonstrate about 10 to 15 percent improvement for throughput and Packet Delivery Ratio, while the average end to end delay seems to be degraded by a considerable degree because of the mutual communication of the cluster heads. The energy consumption of CDSDV is inadequate as it utilizes a slightly more energy than the standard DSDV.
