Power-controlled matiple access schemes for next-generation wireless packet networks
Nicholas Bambos, S. Kandukuri · IEEE Wireless Communications · 2002
We introduce a novel formulation of the power control problem in wireless networking, which is especially appropriate for packet-based wireless communication, capturing the fundamental packet delay vs. transmission power trade-off. Model analysis under simple, yet natural, assumptions yields ubiquitous structural properties of optimal power control schemes, which are then leveraged in the design of a new family of distributed algorithms for power-controlled multiple access (PCMA). Their experimental evaluation by simulation demonstrates performance gains over standard approaches. This is a first step toward designing efficient PCMA protocols for shared channel access in wireless packet networks.
