Non-Cooperative Game Based Research on Routing Schemes for Wireless Networks

Abstract

Since wireless networks are usually distributed,independent and mobile,their performance could be affected by selfish nodes.In this paper,the authors focus on the issues of selfish nodes in wireless networks.Game based mechanisms are introduced to study the wireless network involving selfish nodes.In the literature,there are mainly two approaches to deal with the selfish nodes: credit based mechanisms and non-cooperative game and incentive based mechanisms.The authors summarize and analyze the typical routing mechanisms in these areas,and especially discuss the non-cooperative game and incentive based routing mechanisms for wireless ad-hoc networks and wireless mesh networks.Network coding as an efficient technology can help to improve network performance.They also study the optimization schemes based on network coding in wireless networks involving selfish nodes.Moreover,the authors discuss the collusion problem in non-cooperative wireless networks.Finally,they present the existing challenges and possible research directions in non-cooperative wireless networks.
