Abstract:

The broadcasting protocol can dramatically affect the performance of Mobile Ad Hoc Networks (MANET). Proper use of a counter-based scheme can reduce the number of rebroadcasts, and as a result reduce the chance of contention and collision among neighboring nodes. While most previous studies have used a FIXED counter-based irrespective of node/network status, this research demonstrates that dynamically adjusting the counter-based to take into account node status (e.g. neighborhood information over one hop) greatly improves network performance in terms of both saved rebroadcasts and degree of reachability. This paper presents new smart counter based broadcast algorithm where the threshold value at the nodes is dynamically adjusted using one-hop neighbourhood information. We have conducted a set of simulation experiments in order to characterise node neighbourhood in MANETs using ‘Hello’ packet exchange.
