Wireless ad hoc networks have become an important area of research in wireless communications systems. Unlike some existing networking technologies such as Internet Protocol (IP) networks or cellular systems, wireless ad hoc networks have the advantage that deployment of networks does not require preexisting infrastructures. Ad hoc networks have neither fixed topology nor centralized servers; it is assumed that, once deployed, the network nodes would self-configure to provide connectivity and form a communications network. Communications are vital for effective management and execution of disaster response and recovery efforts emergency response personnel must be able to exchange information with each other from anywhere, at any time, to successfully fulfill their missions.
