A mobile ad hoc network is a collection of wireless terminals that can be deployed rapidly. Its deficiencies include limited wireless bandwidth efficiency, low throughput, large delays, and weak security. Integrating it with a well established cellular network can improve communication and security in ad hoc networks, as well as enrich the cellular services. The integration of heterogeneous wireless technologies can improve the network performance, thereby meeting the demands for different Quality of Service (QoS).
