Comparative Analysis of Group Mobility Models in MANETs based on Bird Flocking

Mobile Ad hoc Networks are collection of mobile nodes forming an ad hoc network without any fixed centralized network. Actual problem of this network is rapid mobility i.e., Mobile nodes are frequently changing their position. Node mobility is one of the major parameters that affect the performance of routing protocols. In order to avoid this problem, Bird Flocking group mobility is combined with popular existing mobility models and routing protocols. In this paper, three group mobility models and reactive routing protocols such as Ad hoc On Demand Vector (AODV) protocol, Dynamic Source Routing Protocol are compared. The results acquired through experiments in terms of performance metrics, such as packet delivery ratio, throughput and end to end delay, Bird flocking mobility gives better results when compared with existing mobility models are Column, Nomadic, Pursue and Reference Point Group Mobility model (RPGM).
