Ultra Smart Counter Based Broadcast Using Neighborhood Information in MANETS
Amarsinh V. Vidhate, Ramrao Adik · 2012
Broadcasting protocol heavily affects performance of Mobile Ad Hoc Networks (MANET). Counter-based scheme can reduce the number of rebroadcasts, and as a result reduce Broadcast Storm Problem. Previously fixed counter-based broadcasting was used irrespective of node/network status; this research demonstrates that dynamically adjusting the counter-based to take into account neighborhood information over 1- hop improves network performance in terms of both saved rebroadcasts and degree of Reachability. This paper presents Ultra Smart Counter Based Broadcast Algorithm [USCBA] where the threshold value at the nodes is dynamically adjusted using one-hop neighborhood information. We have conducted simulation experiments to characterize node neighborhood in MANETs using ‘Hello’ packet exchange. This research argues that neighboring information could be used to better estimate the counter-based threshold value at a given node. Additionally results of extensive simulation experiments performed in order to determine the minimum and maximum number of neighbors for a given node is shown. This is done based on locally available information using AODV protocol and without requiring any assistance of distance measurements or exact location determination devices.
