A mobile ad hoc network is a wireless network that is self-organized with many mobile nodes. No static infrastructure such as a wired backbone is available. All nodes are free to move around and the network topology may change frequently. Due to limited transmission range of wireless network interface, nodes are required to forward messages for those located outside the radiocoverage, thereby forming a multi-hop network. Possible applications include emergency rescue in disaster situations, communication between mobile robots, exchanging information in the battlefield etc. Each node can directly send information in single hop within a pre-specified circle around the node.
