Unmarked point and adjacency vertex, mobility models for the generation of emergency and rescue scenarios in urban areas

Abstract:

In disaster situations, where ad hoc mobile networks are normally used, the location and quantity of existing obstacles is random. Most exist- ing mobility models have not been developed with consideration of the obstacles that exist in a disaster environment. This paper proposes two methods of mobility that realistically represent movement in an environ- ment with obstacles. Unmarked Point Model (UPM) uses a high granu- larity strategy and Adjacency Vertex Model (AVM) uses a method that selects the shortest pathway. UPM consumes more resources than AVM to generate node mobility patterns in an ad hoc network, on a real map area of an urban area, where obstacles have been placed to simulate an emergency and rescue scenario. In addition, a comparative analysis of both models in its routing performance is done using AODV [18].
