Peer selection is one of the key issues in wireless peer-to-peer (P2P) networks and most of the traditional methods and algorithms those have been proposed are only based on homogeneous network. However, networks in the future will be highly heterogeneous. Different kinds of wireless networks such as GSM, UMTS, WLAN, exist together in the same area and different networks have different features and...
Peer selection is a multi-criteria decision making problem. In order to improve the accuracy of peer selection in mobile peer-to-peer (P2P) networks, this paper proposes an integrated approach of Analytic Hierarchy Process (AHP) and Grey Relation Analysis (GRA) to consider various correlative parameters in selecting the optimum peer. The proposed scheme comprises two parts. The first part employs...
In P2P file sharing systems over mobile cellular networks, the bottleneck of file transfer speed is usually the downlink bandwidth of the receiver rather than the uplink bandwidth of the senders. In this paper we consider the impact of downlink bandwidth limitation on file transfer speed and propose two novel peer selection algorithms named DBaT-B and DBaT-N, which are designed for two different cases...
In mobile P2P systems over 3G cellular networks, traditional peer selection algorithms with the idea of traffic localization are not suitable due to the architecture and characteristics of 3G cellular networks. In this paper we propose a novel peer selection algorithm named CFPL for mobile P2P systems over 3G cellular networks. By taking not only the available uplink bandwidth of peers but also the...
Due to the architecture and characteristics of 3G cellular networks, peer selection algorithms with the idea of traffic localization are not suitable for mobile P2P systems in 3G cellular networks, and load balance on the cells should be taken into account. In this paper, we propose a peer selection algorithm named CFLB for mobile P2P systems in 3G cellular networks. The CFLB algorithm always chooses...
The features of P2P networking architecture can contribute to robustness and scalability, however, it also introduces network-oblivious traffic, which brings big pressure to the ISPs. Meanwhile, since traffic of P2P applications occupies much of bandwidth in bottleneck links, non-p2p applications may be severely harmed due to lack of bandwidth. To conquer this problem, previous works mainly focused...
