Summary: | 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 the cellular network with the ad hoc network (independent basic service set) in the wireless local area network (WLAN) and reserves the advantages of sizable coverage in the cellular network and high data rate in the deployable ad hoc network. It also enlarges the scope of communication for the ad hoc network and improves the throughput for the cellular network. Consequently, nodes in HWN can communicate with each other or access the Internet ubiquitously. We also address the routing issues for HWN, because the routing protocol for HWN is different from those used in the cellular network or the 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, the proposed routing performance on HWN and the overhead of the control traffic. Also, we demonstrate the effects of connectivity corresponding with service rate and routing types corresponding with bandwidth restriction in HWN. |
