The autonomous behaviors of peers are usually neglected in the topology formation and adaptation in P2P network, thus a large number of Free-rider and Malicious peers would reside in the center of network, which degrades the user perceived QoE and overall network performance. In this paper, a novel and fully distributed approach Topology Adaptation algorithm based on Reciprocal Contribution (TARC)...
The relay selection problem in a large wireless sensor network (WSN) with uniformly distributed identical nodes is investigated for a two-phase cooperative protocol where the signal transmitted from a single source is overheard by the network and is then relayed by multiple selected nodes subject to a total average transmission power. First, a relay selection technique is considered that maximizes...
Cooperative diversity is a useful technique to increase reliability and throughput of wireless networks. To analyze the performance gain from cooperative diversity, outage capacity is an important figure of merit that captures the inherent diversity-multiplexing trade-off in cooperative diversity schemes. In this paper we derive the outage capacity for several cooperative diversity schemes in decode-and-forward...
