Joint Scheduling and Rate Control for Self-Configuring Ad-Hoc CDMA Networks

摘要

The proliferation of wireless technology and the increasing demand for wireless data services have led to a re-examination of wireless network design, particularly with respect to optimal resource allocation. In a wireless ad-hoc environment, the lack of infrastructure, the need to perform resource allocation in a distributed fashion, and the time-varying nature of the network makes proposing an optimal design a difficult task. In this paper, we examine ad-hoc wireless networks in the context of variable-rate TCDMA (time and code division multiple access). We formulate this as a joint time-slot/rate assignment optimization problem, and present a simple algorithm that, while not producing an optimal result, is guaranteed to produce a feasible time-slot/rate assignment. This algorithm results in a self-configurable system with fault recovery capability.
