Packet distribution for complex wireless access route using IEEE802.11/802.16 and its field trial

The diversification of wireless communication usage has been proceeding rapidly with the diffusion of cellular phones, WiFi and WiMAX. In the emerging wireless communication environments, diverse wireless systems coexist. On the other hand, there is increasing concern that the growing use of wireless systems will exhaust the finite wireless resources. To solve this problem, we aim to optimize the utilization of wireless resources by combining communications among multiple wireless interfaces. In this paper, we propose a packet distribution for complex access route combining IEEE802.11/802.16 wireless links in parallel and tandem, and show its performance in field trial. The proposed method improves delay and throughput in the network by taking full advantages of wireless media diversity.
