Fairness in Wireless Networks:Issues, Measures and Challenges

Abstract

Fairness is an important and interdisciplinary topic employed in many fields. This article discusses fairness issues in wireless networks. First, we address various issues in the study on fairness. In general, we formulate the issues in fairness research through the three core questions. Finding answers them leads us to various nuances of fairness studies. Existing fairness models are summarized and compared. We also look into the major fairness research domains in wireless networks. Relationship between fairness, utility and resource allocation are also discussed. At the end of this article, we provide properties of fairness and an example fairness management process. We also state some challenges that point to further work on fairness in wireless networks. Indeed research on fairness is entangled with various other aspects such as performance, utility, optimization and throughput at the network as well as individual (or node) level. While consolidating various contributions in the literature, this article tries to explain the nuances of all these aspects clearly in the domain of wireless networking.

Optimization Based Hybrid Congestion Alleviation for 6LoWPAN Networks

“…In our framework, we use the logarithmic utility function as it has strict concavity property. Also, different utility functions exist in term of fairness such as proportional fairness, weighted proportional fairness and max-min fairness [42]. We select the weighted proportional fairness to satisfy that each node obtains sending rate according to its priority.…”

User Fairness in NOMA-HetNet Using Optimized Power Allocation and Time Slotting

“…While QoS fairness has been well studied, focus on fairness from perspective of the users need to be established. The work in [9], [10] argues that a it is not necessary that a system which is QoS fair is also QoE fair. Hence, it is important to consider fairness from the QoE perspective as well.…”

Optimization of distributed detection in energy harvesting wireless sensor networks with multiple antenna fusion center

“…Normally, the local sensors are fed by small batteries, and their replacement is challenging or noneconomic. Therefore, power management is an important principle in application detection …”

“…Therefore, power management is an important principle in application detection. 11 Shahzad et al 12 studied the full-duplex receiver for covert wireless communications for detecting a target. However, in their method, the sensors have always fixed position in transmitting data or energy and have not considered the ability to modify the sensor from the state of transmitter to the state of collecting energy and data according to the position and the channel access quality for the relay sensors.…”
