Behaviour Of Routing Protocols in Manets Investigated For Emergency And Rescue Situation In Sudan

Abstract

Disaster Area Network (DAN) is very crucial in case of natural or man-made disasters. During state of emergency, a rapidly deployable network is the highest priority to conduct search and rescue operations. This research aims at investigating network architecture and routing models for disaster area networks. The main objective and goal of DAN is to ensure reliable, energy efficient communication which is susceptible to mobility and topology changes in the disaster area. The purpose is to improve delay, reduce overhead, minimize energy used, sustain movement and increase bandwidth for multimedia applications. Mobile Ad hoc network (MANET) addresses issues related to rapid and temporary setup and terminal probability and mobility in a disaster area until conventional infrastructure communication is established. We study the behavior of two common reactive routing protocols (AODV and DYMO) in disaster area in different scenarios using OMNET++ simulator to define the suitable protocol in the studied area, in order to insure reliable communication. At the end of the research we obtained that, DYMO is more reliable and stable than AODV, so we recommend to use it in our study case DAN (Marabee Al- shareef).
