Network coded partners selection between cooperative nodes in air-based wireless networks

This paper presents a selection and grouping algorithm based on proposed network coded cooperative strategy in aeronautical communications. In such a practical scenarios, communications between high-speed mobile nodes are troubled with high reliability and capacity demands of the emerging aeronautical applications. The idea of network coded cooperative strategy is combining information at the relay and joint decoding at the destination, which could improve reliability and capacity without much loss of throughput of the whole networks. Then, we consider the selection and grouping algorithms in this context. An adjacency matrix is defined to describe the connection of the nodes in one radio contact disk, so that, the selection and grouping algorithm is equal to construct this adjacency matrix avoiding girth 4 and minimize the system outage probability. At the end of the paper, simulations and results will be given to demonstrate the algorithms.
