The most important requirement of mobile communication and computing is the unlimited mobility i.e. the user can communicate anywhere within the coverage area of the network. There are two versions of mobile wireless networks, the first one is an infrastructure based network where the last hop may be wireless and the other a multihop ad hoc wireless network that has no infrastructure this evolves the concept of ad hoc network. Mobile ad hoc network (MANET) has numerous applications in modern communication system (disaster management system, military application and many others). Spectrum is...
