Abstract:
A Mobile Ad-hoc network (MANET) is a multi-hop wireless network where all nodes cooperatively maintain network connectivity without a centralized infrastructure, and nodes change their positions dynamically. Most studies in MANETs are focused on scenarios with special characteristics. These are: Random waypoint mobility model, 40% transmitting/receiving nodes, and high density of mobile nodes in the scenario area. Our framework aims to evaluate the impact of mobility models, network density, and different percentages of transmitting/receiving nodes on the performance of MANET routing protocols. In this paper a study 27 different scenarios which aim to study the joint effect of different densities of mobile nodes in the scenario area; Three different mobility models; as well as different percentages of transmitting/receiving nodes. Each scenario is evaluated for both the location aided routing (LAR) and ad-hoc on demand distance vector (AODV) routing protocols. Performance evaluation metrics included packet delivery ratio, overhead, and the average end-to-end delay. These metrics were evaluated for a speed of the mobile nodes in the range from 1 to 40 meters/sec. We analyzed the results and compiled a catalogue for MANETS that can be used to deploy the best suitable routing protocol for each scenario of choice.
