Abstract
Cooperation among network devices is a promising solution to improve network throughput and network service quality. In addition, it can be used to enhance network survivability against failures. In this paper, we study the user cooperation solution of multipath streaming application on wireless user equipments (UEs) using auction theory. We assume that UEs use multipath transport layer service, and establish two paths for streaming events, one path goes through its cellular link, another path is established using a Wi-Fi connection with a neighbor UE. We propose two user cooperation schemes (LCF and EAC) for UEs to participate in the user cooperation system. We compare the performance of using LCF and EAC schemes to the scheme without cooperation, and the simulation results show that applying the proposed user cooperation scheme and establishing multipath connections for the streaming event can reduce up to 60% of total energy consumed. LCF scheme can also help balance the energy consumption among UEs in the system.
