This paper investigates the scalability and communication among multiple rescue teams. A number of rescuers have to scan an area for airplane crash survivors. The rescuers are divided into a number of teams. Each team has to scan a specific sub-area. A commander coordinates the leaders of the teams and each team leader coordinates the members of his team. Thus, there is localization of communication inside each team. A MANET (Mobile Ad Hoc Network) is deployed in the area and multicasting is used to support the coordination and communication. The PDR (Packet Delivery Ratio) and the Latency of two multicast protocols are measured via simulation with respect to the number of teams, the rescuers’ speed and the antenna range. The ODMRP protocol is better. For the given scenario of 120 rescuers scanning an area of 4Km * 3Km, it is preferable to create 4 teams. Each team is composed from 30 rescuers and scans a sub-area of 2Km *1.5Km. The rescuers may use antenna range of 500m.
