RTTMM: Role based 3-Tier Mobility Model for Evaluation of Delay Tolerant Routing Protocols in Post Disaster Situation

Nikhil Gondaliya, Mohammed Atiquzzaman


In Internet of Things (IoT) the devices are interconnected through Internet with several redundant paths but they are still vulnerable to the effects of large scale disasters such as earthquakes and floods. The disaster area may be disconnected from the rest of the Internet and the need arises to get information about the victims. Adhoc networks like MANETs and DTNs are most suitable to support the communication in partitioned networks, such as a network in a post disaster situation. Even an adhoc network become one of the essential network architecture in IoT and attracted lot of attention in last decade. The disaster affects the several regions with different intensities called each region as disaster event which are located nearer to each other. Each disaster event is assigned group of rescue entities with hand held IoT device, where they perform the tactical operation. The movement pattern of the rescue entities in a post disaster area is described by a mobility model which is used to evaluate the routing protocols for post disaster scenario networks. Existing mobility models for post disaster scenarios do not distribute the rescue entities in proportion to the intensity of disaster events in the case of multiple events occurring simultaneously. The movement characteristics of devices carried by rescue entities affect the performance of network so, their mobility must be modelled and tested using DTN routing protocols. In this work, we propose the Role-based 3-Tier Mobility Model (RTTMM) to mimic the movement pattern of different rescue entities involved in the disaster relief operation by distributing them based on the proportion of the intensity of the disaster event. We also evaluated the performance of existing DTN routing protocols using the traces obtained from RTTMM. RTTMM replicates the movement patterns of rescue entities having pre-assigned unique roles. Our model generates the mobility traces of the rescue entities, which are fed as input to the DTN routing protocols. The main contribution of this paper is to model the movement pattern of rescue entities and evaluate the performance of existing DTN routing protocols using the movement traces from RTTMM. RTTMM can be used to model the movement pattern of rescue workers when multiple disaster events occur simultaneously with different intensities. The evaluation of existing DTN routing protocols allow selection of suitable routing protocol for RTTMM.
