Modelling Mobility Based on Human Behaviour in Disaster Areas
Mobility models are used to mimic the realistic movement of entities. Mobility models for wireless networks feature different objectives and characteristics, most based on random behaviour. However, random based mobility models, e.g. Random Waypoint (RWP), are often not suitable to represent the reality of node mobility, particularly in disaster areas where the search time for victims is a critical factor. Moreover, the studied mobility models for disaster environments are either random based or not suitable for such scenarios. This work proposes a new mobility model based on Human Behaviour for Disaster Areas (HBDA) to properly evaluate the performance of mobile wireless networks in disaster environments. HBDA is designed to cover as much area as possible, regarding search time as an important factor. This work evaluates HBDA concerning movement and link performances. Results show that HBDA provides an even distribution of nodes, a high coverage area and an efficient routing performance.
