Future information technology will be mainly based on wireless technology [49, 50, 56]. Traditional cellular and mobile networks are still, in some sense, limited by their need for infrastructure (i.e., base stations, routers). For mobile ad hoc networks, this final limitation is eliminated. Ad hoc networks are key to the evolution of wireless networks [48]. Ad hoc networks are typically composed of equal nodes that communicate over wireless links without any central control. | Handbook of Wireless Networks and Mobile Computing Edited by Ivan Stojmenovic Copyright 2002 John Wiley Sons Inc.
