Efficient Routing with Reduced Routing Overhead and Retransmission of Manet
Megha Sharma · American Journal of Networks and Communications · 2015
Adhoc network is a collection of mobile nodes that dynamically form a temporary network and are capable of communicating with each other without the use of a network infrastructure. In manet nodes can change location and configure itself, the mobility of nodes causes continuous link breakage due to which frequent path failure occur and route discovery is required. The fundamental construction for a route discoveries is broadcasting in which the receiver node blindly rebroadcast the first received route request packet unless it has route to the destination. The routing overhead associated with route discovery is very high which leads to poor packet delivery ratio and a high delay to be victorious this type of routing overhead we are proposing the new technique using NCPR. To intended NCPR method is used to determine the rebroadcast order and obtain the more precise additional coverage ratio by sensing neighbor coverage knowledge. We can also define connectivity factor to provide node density adaptation. By combining the additional coverage ratio and connectivity factor, rebroadcast probability is determined. The approach can signify improvement in routing performance and decrease the routing overhead by decreasing the number of retransmission.
