End-to-End Multiservice Delivery in Selfish Wireless Networks Under Distributed Node-Selfishness Management

Abstract

In this paper, we investigate the multiservice delivery between the source–destination pairs in distributed selfish wireless networks (SeWN), where selfish relay nodes (RN) expose their selfish behaviors, i.e., forwarding or dropping multiservices. Owing to the effect of the RNs’ node-selfishness on the multiservices, a distributed framework of the node-selfishness management is constructed to manage the RN’s node-selfishness information (NSI) in terms of its available resources, the employed incentive mechanism and the quality-of-service (QoS) requirements, and the other RNs’ NSI in terms of their historical behaviors. In this framework, the RNs’ NSI includes the degree of node-selfishness (DeNS), the degree of intrinsic selfishness (DeIS) and the degree of extrinsic selfishness (DeES). Under the distributed node-selfishness management, a path selection criterion is designed to select the most reliable and shortest path in terms of RNs’ DeISs affected by their available resources, and the optimal incentives are determined by the source to stimulate forwarding multiservices of the RNs in the selected path. Our simulation results demonstrate that this framework effectively manages the RNs’ NSI, and the optimal strategies of both the path selection and the incentives are determined.
