Performance comparison of mobility models in Mobile Ad Hoc Network (MANET)

Mobile Ad Hoc Network (MANET) consists of a group of mobile or wireless nodes that are situated randomly and dynamically which causes the continuous change between nodes. When considering a mobility model and protocol to deploy in any given situation, factors such as the mobility of nodes, the network size and packet size should be carefully considered because mobility models can highly affect the performance of MANET and its routing protocol. This paper compared the performance of two different mobility models (i.e. Random Waypoint and Manet_Down_Left) in MANET. These models were configured with Optimized Link State Routing (OLSR) protocol. The simulated results indicated that Random WayPoint configured with OLSR performed better in all scenarios where the pause time and speed were varied (i.e. 5s and 5–10m/s respectively; and 15s and 25–30m/s respectively).
