The past decade has shown a phenomenal growth in wireless communications. Cellular systems have been standardized and Personal Communication Services (PCS) and the 3rd generation radio technology are being used providing wide-band services to mobile users.
In parallel with (and separately from) the single hop model for todays cellular/wireless communications, another type of model based on radio to radio multihopping, has been evolving to serve a growing number of applications which rely on a fast deployable, multihop, wireless infrastructure. A multihop mobile radio network, also called mobile ad hoc network (MANET) is a self-organizing and rapidly deployable network in which neither a wired backbone nor a centralized control exists. The network nodes communicate with one another over scarce wireless channels in a multi-hop fashion. The ad hoc network is adaptable to the highly dynamic topology resulted from the mobility of network nodes and the changing propagation conditions.
MANETs are a new paradigm of wireless wearable devices enabling instantaneous person-to-person, person-to-machine or machine-to-person communications immediately and easily. Possible commercial applications include business associates sharing information during a meeting, students using laptop computers to participate in an interactive lecture, and emergency disaster relief personnel coordinating efforts in natural disasters. In these applications, where a fixed backbone is not available, a readily deployable wireless network is needed. Mobile ad hoc networks are also a good alternative in rural areas or third world countries where basic communication infrastructure is not well established. Another interesting application of mobile ad hoc networks is ubiquitous computing. Intelligent devices are connected with one another via wireless links and are self-organized in such a way that a newly joined node can request service from local servers without any human intervention.
