Abstract

A Mobile Ad-hoc Network (MANET) is a self-starting dynamic network made up of mobile nodes where each and every participation node willingly transmits the packets destined to some remote node using wireless transmission. One of the key features of MANET is that it can be formed without any preexisting infrastructure. One of the types of routing protocols used in MANET is the hybrid protocol which combines the advantages of the proactive and the reactive protocols. In this paper, three Hybrid routing protocols in MANET were examined, namely: Adaptive Distance Vector routing protocol, Zone Routing Protocol (ZRP) and Sharp Hybrid Adaptive Routing Protocol (SHARP). Simulation was carried out on the aforementioned protocols using some parameters. After obtaining the results of the simulation tests, the three hybrid protocols were then compared with one another using the metrics of throughput, packet delivery ratio and average endto-end delay. Based on the result of the performance comparison we were able to ascertain which protocol is better than the others in terms of the metric in question.
