Modeling human mobility in obstacle-constrained ad hoc networks
The search for service providers (e.g., ambulance, fire truck, etc.) after a disaster, must take place within ashort time. Therefore, service discovery protocol which looks forproviders that can attend victims, respecting time constraints, iscrucial. In such a situation, a commonly solution for ensuringnetwork connectivity between victims and providers is ad hocnetworks (MANET), composed by battery-operated mobile nodesof persons (victims or not). However, an efficient service discoveryprotocol must care about energy consumption of mobile nodesand also prevent useless movement of providers. These are theaims of the Resource Reservation Protocol (Δ RRP), presentedin this paper. Applying both Gauss-Markov  and MissionCritical Mobility  models to characterize human mobility, performance evaluation results on the Network Simulator NS-2 confirm the effectiveness of Δ RRP protocol when comparedto other protocols.
