To mitigate the damaging impacts caused by interference and hidden terminals, it has been proposed to use orthogonal channels in wireless multi-hop mesh networks. We demonstrate however that even if these issues are completely eliminated with perfectly assigned channels, gross unfairness can still exist amongst competing flows which traverse multiple hops.We propose the use of 802.11e’s TXOP me...

Cheating is a key issue in multiplayer games as it causes unfairness which reduces legitimate users’ satisfaction and is thus detrimental to game revenue. Many commercial solutions prevent cheats by reacting to specific implementations of cheats. As a result, they respond more slowly to fast-changing cheat techniques. This work proposes a framework using Event-B to describe and detect cheats fr...

We demonstrate however that even if these issues are completely eliminated with perfectly assigned channels, gross unfairness can still exist amongst competing flows which traverse multiple hops.

Traffic markers differentiate among packets from senders based on their service profile in the differentiated service networks. Researchers have previously revealed that the existing marking mechanism causes the unfairness in aggregates. This study presents a new marking algorithm. Simulation results demonstrate that the fairness of the proposed scheme exceeds that of SRTCM, TRTCM, TSWTCM and I...

In this paper, we propose an efficient and stable algorithm employing fuzzy logic for available bit rate (ABR) traffic. Large time-delay incurred in the feedback path and the statistical variation in the link capacity at the ATM node can cause instability or unfairness. The stability and fairness issues are discussed and the performance of the proposed mechanism is evaluated. key words: ABR, AT...

The TCP-friendly rate control (TFRC) algorithm has been proposed for supporting applications such as video streaming or telephony over the Internet, where a relative smooth sending rate is of importance. The fairness and friendliness of TFRC over scenarios with multiple congested routers is evaluated. Results obtained using the ns-2 simulator show that while TFRC improves network utilisation wi...

Purpose Global product-harm crises increased in recent years. After such crises, firms' product-recall policies varied across countries, which might cause consumers some countries to feel unfairly treated. Drawing on the relative deprivation theory, this study aims examine how perceived unfairness of local alters their attitudes toward unfairness-enacting foreign brands and competing domestic b...

Issues directly or indirectly related to the increasing costs of health care services have the potential to adversely affect physicians' fiduciary responsibilities to their patients. Coding deception in response to perceived unfairness in reimbursement practices represents one of these potential adverse influences. This case discussion addresses the potential motivations underlying coding decep...
