Abstract

In traditional infrastructure-based IEEE 802.11 wireless LAN network, all the mobile nodes associated themselves with an access point (AP) share the same wireless channel with other mobile devices. In such wireless network environment, there are two major inefficiencies: (a) load imbalance among different APs: when the distribution of the location of mobile nodes is non-uniform, this might result in a situation where a lot of mobile nodes access a single AP and the rest of APs are idle, and (b) poor resource utilization: most of the mobile nodes contend for the wireless channels of APs while there are some unused and available wireless channels, which can be used to set up ad hoc groups. In this paper, we propose the hybrid WLAN(H-WLAN) framework to address these two problems. First, our H-WLAN framework provides the adaptive service selection module for the mobile node to figure out a better wireless channel and the server to get its service. Second, the popularity-aware channel management module is able to efficiently integrate the ad hoc mode with the infrastructure mode by allowing mobile nodes to set up a new ad hoc group and then share their resources with other nodes within that group. The simulation results show that our H-WLAN framework can substantially (a) achieve high utilization and load balance among wireless channels with lower control overhead, and (b) provide better quality of service for the mobile nodes.
