A resource allocation strategy for meshed high data rate WPANs

Abstract

In order to extend the operating space of single hop High Data Rate (HDR) Wireless Personal Area Networks (WPANs), the meshed configuration can be used for multi-hop functionality. Since the superframe is shared between multiple WPAN piconets for communication, with higher device density, the superframe capacity usually proves to be a bottleneck. Furthermore, when the superframe capacity is shared in a distributed fashion, issues of fairness in time allocation arises. In this paper we propose a centralized scheme for resource allocation specifically in meshed WPANs and induce an element of fairness in time allocation. Simulation results prove the effectiveness of the proposed approach.
