Balancing Energy Efficiency and Throughput Fairness in IEEE 802.11 WLANs
The proliferation of wireless networks based on IEEE 802.11 has resulted in a heterogeneous set of devices using a variety of applications to compete for the desired service performance. Most notably, the class of highly mobile and energy constrained devices is showing high growth rates. Yet, fairness of resource allocation is still only considered in terms of achievable throughput and without considering energy efficiency. In this paper, the authors show that performing energy efficient and fair resource allocation in current IEEE 802.11 WLANs is challenging, given the diversity of power consumption figures among mobile devices.
