Recently network coding has been proven as a very promising technique to improve wireless network throughput. In multi-rate wireless networks, simply seeking more coding opportunities or coding more packets into one frame without exploiting multi-rate feature may lead to selecting low-rate links for transmission, and thus compromise the performance gain brought by network coding. In this paper, we...
Recently energy-efficient system design in wireless networks, which in nature supports multi-rate transmissions, has become a focus in the research field. Meanwhile network coding has been proven as a very promising technique to improve wireless network throughput and energy-efficiency (EE). In multi-rate wireless networks, simply seeking more coding opportunities or coding more packets into one frame...
Due to the mass-market of file sharing, majority of existing P2P systems are based on unstructured overlay networks, where P2P search still remains challenging issues. In this paper, we propose a small-world based semantic search architecture in P2P Networks, called CommuSearch, which has three distinguished features: 1) grouping peers into hierarchical class by exploiting heterogeneity; 2) constructing...
To reduce influence of node failure and achieve high reliability in communications, research on node protection algorithm is needed. In this paper, we first provide an overview of current research of redundant tree algorithm (RT). Then we propose a new algorithm called single node protection algorithm (SNP) based on previous redundant tree algorithm, which is used to achieve recovery form single node...
