Broadcasting Protocols in Mobile Ad-hoc Network: Performance Comparison, Improvement and Suggestion

In future, Mobile Ad-hoc network (MANET) are expected to be deployed in various scenarios having complex node mobility and connectivity dynamics . For example, on a battlefield, the movement of the soldiers (the nodes) is influenced by the commander and in a city, the node movement is controlled by the maps. Widely varying broadcasting techniques are expected to have a significant impact on the performance of the routing protocols in Ad-hoc networks. This book presents an overview on the state of the art of broadcasting techniques in mobile Ad-hoc networks, compare their performance and make recommendations to improve the efficiency of current and future broadcasting techniques. I specially make comparison between simple flooding broadcast and probabilistic broadcast (with 7 different probability) by using two parameters (average number of redundant broadcast and average number of single broadcast). At last, I give suggestion to make optimal power efficient broadcast. From this work, analyzing the collected data, I found that Probabilistic broadcast with approximately 0.275 probability is the best one.
