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...
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...
In most structured P2P systems, using DHT algorithms to distribute objects randomly among nodes results in unbalance load in each node. Numerous load balancing proposals exist in P2P networks, most of them only focus on namespace balancing and under the uniform assumption. In ideal condition, these techniques really work well, but ignoring the effect of heterogeneity and uneven in both of varying...
In this paper, we present our design and implementation of load-balanced gateway discovery routing protocol called LBGD-AODV. A gateway node in a wireless mesh network acts as bridge between mesh routers and external network in order to provide services such as broadband. We observed in our SwanMesh testbed that a single gateway can only serve up to a limited number of hops due to noticeable throughput...
