BitTorrent is a peer-to-peer (P2P) file sharing protocol, which overcomes the bottleneck of server bandwidth by allowing peers to share the downloaded data directly. However, the greedy and non-cooperative behavior (such as leeching) of individual peer can degrade the performance of P2P significantly. In this paper, we optimize the non-cooperative P2P network from the game theory point of view. Specifically,...
The introduction of relay station (RS) nodes is a key feature in next generation wireless networks such as 3GPP's long term evolution advanced (LTE-Advanced), or the forthcoming IEEE 802.16j WiMAX standard. This paper presents, using game theory, a novel approach for the formation of the tree architecture that connects the RSs and their serving base station in the uplink of the next generation wireless...
In current peer-to-peer file sharing networks, a large number of peers with heterogeneous connections simultaneously seek to download resources, e.g., files or file fragments, from a common seed at the time these resources become available, which incurs high download delays on the different peers. Unlike existing literature which mainly focused on cooperative strategies for data exchange between different...
In this paper, we propose a game theoretical approach to tackle the problem of the distributed formation of the uplink tree structure among the relay stations (RSs) and their serving base station (BS) in an IEEE 802.16j WiMAX network. Unlike existing literature, which focused on the performance assessment of the network in the presence of the RSs, we investigate the topology and dynamics of the tree...
Autonomous agents such as unmanned aerial vehicles (UAVs) have a great potential for deployment in next generation wireless networks. While current literature has been mainly focused on the use of UAVs for connectivity enhancement and routing in military ad hoc networks, this paper proposes a novel usage model for UAVs in wireless communication networks. In the proposed model, a number of UAVs are...
Peer-to-peer (P2P) systems have become more and more popular in nowadays by providing decentralized, self-organizing and fault tolerant file sharing services. As the selfish users do not benefit from providing free service, they tend to download files from other users and yet not to upload for the others, resulting in low system efficiency. In this paper, we propose a correlated equilibrium-based...
