Minimizing the Overhead caused due to dynamic nodes in Mobile Ad-hoc Networks using Zone routing protocol

Abstract

Opportunistic data forwarding has become a interesting topic in the multi-hop wireless networking. Opportunistic data forwarding is not used in mobile ad hoc networks (MANETs) due to the lack of an efficient lightweight proactive strong source routing scheme. Proactive Source Routing uses Breadth First Spanning Trees (BFSTs) and maintains more network topology information to facilitate source routing. Although it has greatly reduced overhead than traditional link state (LS)-based routing protocols and reactive source routing protocols, the computational and memory overhead involved in maintaining BFSTs to reach every node in the denser networks will be high. In this paper Zone-based Proactive Source Routing Protocol is proposed. Zone routing protocol (ZRP) uses partition based routing. The ZRP make use of source routing inside a zone and on-demand routing outside the zone. This approach combines the advantages of both proactive and zone based routing protocols. The simulation shows that the Z-PSR i.e. zone based proactive source routing protocol performs better compared to PSR.
