In conventional binary network coding (BNC), the decode condition constrains the achievement of diversity gain. In this paper, a novel network-coded scheme is proposed, where the inter-rely cooperation (IRC-NC) is employed to loose the above restriction. Firstly, two relays are divided into NC node and assistant node according to their channel gain to destination. This process is accomplished by the...
In this paper, we consider adaptive cooperation and relay selection for opportunistic system. A novel hybrid opportunistic cooperation strategy with log likelihood ratio (LLR) threshold is proposed in order to combat error propagation. Firstly, we combine the proactive and reactive opportunistic relaying by employing specific LLR switching thresholds, according to which the best relay and the corresponding...
According to the heterogeneous characteristics of wireless mesh networks and the QoS requirements of multimedia applications, we design a novel QoS adaptive architecture for WMNs that is cross-domain, cross-layer and cross-node. Furthermore, this architecture is mathematically described by using a bi-level programming model. This model uses the optimization results of subnets as the optimization parameters...
