Performance Evaluation of Routing Protocols on the Reference Region Group Mobility Model for MANET

Abstract

Group mobility is prevalent in many mobile ad hoc network (MANET) applications, such as disaster recovery, military operations, searching and rescue activities. Group partition, as an inherent phenomenon in group mobility, may occur when mobile nodes move in diverse mobility patterns and it causes the network to be partitioned into disconnected components. It may result in severe link disconnections, which interrupts network communications. To address this concern, we proposed a novel group mobility model in this paper, namely the Reference Region Group Mobility model, which can be used to mimic group operations in MANETs, i.e. group partitions and mergers. Based on this model, a comprehensive study on the impact of group partitions to the performance of network routing protocols are carried out by evaluating two well-known routing protocols, namely the Ad Hoc On-demand Distance Vector Routing protocol (AODV) and the Dynamic Source Routing protocol (DSR). The simulation results reflect that group partitions have a significant impact to the performance of network routing protocols.

Impact of Random Mobility Models on OLSR

“…The performance of AODV and DSR using reference region group mobility model has been examined in [17]. The reference region group mobility model is used to mimic group operations such as group partitions and mergers.…”

Impact of Mobility on MANETs Routing Protocols Using Group Mobility Model

“…Sometimes there is a need to realize movement of nodes in form of groups and for the same group mobility model is used. The applications of group mobility may are include military operations, searching and rescue in disaster recovery, visiting an exhibition hall, and firefighters operating in a building [1].…”
