Abstract-Over the last decade, many researchers have focused on Mobile Ad Hoc Networks as the main communication method in disaster recovery situations. In these researches, there has been marginal focus on the mobility patterns of nodes in disaster recovery scenarios. In this paper, a deeper analysis has been performed on some of the main mobility models used in testing new protocols and a new mobility model is proposed to incorporate some neglected factors concerned with disaster recovery situations.Keywords-MANETs, Disaster recovery, Mobility Model, Random Waypoint, Routing, Hexacell.
IntroductionManaging disasters and emergency situations requires accurate and precise messages delivery, on which sensitive decisions making in such scenarios depends [1]. Since most of the infrastructure of any communication is eradicated by the strike of the disaster, this can affect rescuing missions and recovery which are timely critical. The alternative should be planned and set for managing the post disaster situations and emergency issues.Disaster perspective, is how people look at the disaster and what they believe that is most critical to be managed after the disaster, which affects the parameters that are chosen and taken into consideration in such situations, this can affect efficiency of disaster management which supposed to minimize losses in lives [2].Communications play a key role in disasters recovery and emergency management situations. Ad hoc networks are infrastructure-less networks which make the main focus of researches is how to implement them in disasters recovery areas. In order for the study of disaster recovery situations to be more realistic and of higher credibility, the mobility model that describes node movement in the network area should be representative and reflects such scenarios. This is the motive behind the proposed model iJOE
