This paper presents a new architecture, Heterogeneous Wireless Network (HWN) and a dynamic adaptive routing protocol (DARP) for HWN. To support ubiquitous communication, HWN integrates cellular network with ad hoc network (independent Basic Service Set) in wireless local network (WLAN) and reserves advantages of sizable coverage in cellular network and high data rate in deployable ad hoc network. It also enlarges the scope of communication for ad hoc network and improves the throughput for cellular network. Consequently, nodes in HWN can communicate with each other or access Internet ubiquitously. We also address the routing issues for HWN, because the routing protocol for HWN is different from those used in cellular network or ad hoc network. The dynamic adaptive routing protocol establishes a better path for the source to arrive at the destination across multiple hops or cellular network and provides appropriate quality of service in HWN. Through simulation, we demonstrate the merit of HWN, proposed routing performance on HWN and overhead of control traffic. Also, we demonstrate the effects of connectivity corresponding with service rate and routing types corresponding with bandwidth restriction in HWN.
