2 gives the major differences between cellular and ad hoc networks. 2 Applications of Ad Hoc Wireless Networks The field of wireless networking emerges from the integration of personal computing, cellular technology, and the Internet. ” At present, a large ­variety of networks exists, ranging from the well-known infrastructure of cellular networks to noninfrastructure wireless ad hoc networks. indd 23 9/21/07 4:34:05 AM 24 � Ad Hoc Mobile Wireless Networks The following are the applications of ad hoc wireless networks: � � � � � � Community network Enterprise network Home network Emergency response network Vehicle network Sensor network Unlike a fixed wireless network, wireless ad hoc or on-the-fly networks are characterized by the lack of infrastructure.

To change the routing requires a new IP address associated with the new point of attachment. Mobile IP has been designed to solve this problem by allowing the mobile node to use two IP addresses. In Mobile IP, the home address is static and is used, for instance, to identify TCP connections. The care-of address changes at each new point of attachment and can be thought of as the mobile node’s topologically ­significant address; it indicates the network number and thus identifies the mobile node’s point of attachment with respect to the network topology.

Connectivity to wired infrastructure will be provided through ­multiple gateways with possibly different capabilities and utilization. 2 Differences between Cellular and Ad Hoc Wireless Networks Cellular Ad Hoc Wireless Networks Infrastructure networks Infrastructureless networks Fixed, prelocated cell sites and base station No base station, and rapid deployment Static backbone network topology Highly dynamic network topologies with multihop Relatively caring environment and stable connectivity Hostile environment (noise, losses) and irregular connectivity Detailed planning before base station can be installed Ad hoc network automatically forms and adapts to changes High setup costs Cost-effective Large setup time Less setup time to variation in performance and coverage and to switch ­gateways when beneficial.
