Abstract

Recentlythe deployment of IEEE 802.11 Wireless Mesh Networks (WMNs) hasbeen growing exponentially because ofemerging ofsharingeconomy of WiFi. As a result, the handoff delay caused by mobile client (MC) probing for the next preferredAP becomes more challenging in a dense WMN. In this paper, we propose a fast handoff scheme T-NRS (Temporal-NRS) which leverages historical knowledge ofAPs associatedin time seriesto assist in handoff decision in addition tothe Network-Assisted Radio Signature(NRS)technique based onspatial knowledge. The enhancement improves the performance whilst eliminates the inflexibility. We implementand evaluate the mechanism in about 200 APs inshopping malls. The results prove the performance of the proposed scheme.
