A Multiplayer Games Priority Selection Strategy for Use in QoS-Aware Networks
نویسندگان
چکیده
Future Quality of Service (QoS) aware networks, such as those based on the Differentiated Services (DiffServ) architecture, will provide users with the opportunity to prioritize the traffic they receive and generate. Different priorities will entail different per-byte or per-packet charges. To aid users operating within such an environment, a priority selection strategy is required. In this paper, we propose a priority selection strategy based on Consumer Surplus (CS), which is the difference between what the user is willing to pay (utility) and the actual cost. We then evaluate this strategy in a networking scenario where a user is involved in a multiplayer Counterstrike game, in which different priorities can be assigned to the downstream traffic. A utility curve, applicable to a First Person Shooter (FPS) game like Counterstrike, is presented. Using simulation results we show that for varied traffic loads, the CS strategy offers comparable application performance to that of always selecting the highest priority. However it does so at a reduced cost to the user..

Real-Time Multiplayer Game Support Using QoS Mechanisms in Mobile Ad Hoc Networks
Real-time applications, especially real-time multiplayer games, are getting popular in mobile ad hoc environments as mobile devices and wireless communication technologies are becoming ubiquitous. However, these applications have strict demands on the underlying network requiring low latency with a minimum of jitter and a small packet loss rate. Therefore, Quality of Service (QoS) support from ...
متن کاملA New Fairness Index and Novel Approach for QoS-Aware Resource Allocation in LTE Networks Based on Utility Functions
Resource allocation techniques have recently appeared as a widely recognized feature in LTE networks. Most of existing approaches in resource allocation focus on maximizing network’s utility functions. The great potential of utility function in improving resource allocation and enhancing fairness and mean opinion score (MOS) indexes has attracted large efforts over the last few years. In this p...
متن کاملStructure coefficients and strategy selection in multiplayer games.
Evolutionary processes based on two-player games such as the Prisoner's Dilemma or Snowdrift Game are abundant in evolutionary game theory. These processes, including those based on games with more than two strategies, have been studied extensively under the assumption that selection is weak. However, games involving more than two players have not received the same level of attention. To addres...

Service-oriented architecture facilitates the running time of interactions by using business integration on the networks. Currently, web services are considered as the best option to provide Internet services. Due to an increasing number of Web users and the complexity of users’ queries, simple and atomic services are not able to meet the needs of users; and to provide complex services, it requ...
