In IEEE 802.11-based multihop wireless mesh networks (WMNs), nodes that are a number of hops away from the gateway (GW) face two-fold contentions: namely channel access contention between itself and other nodes, and traffic contention between its own and relayed traffic. As a result, they suffer from low throughput and even starvation, which results in unfairness in transmissions. In this paper, we...
Heuristic search methods usually require a large amount of evolutionary iterative calculation, which has become a bottleneck for applying them to practical engineering problems. In order to reduce the number of analysis of heuristic search methods, a Pareto multi-objective particle swarm optimization (MOPSO) method is presented. In this approach, Pareto fitness function is used to select global extremum...
Probability theory is a branch of mathematics dealing with chance phenomena and has clearly discernible links with the real world. It is the framework foundations of many applying subjects, such as information theory, mathematics risk theory and Insurance theory for actuaries etc. The strong deviation theorems is one of the central questions for studying in the international probability theory . In...
In this paper, the problem of implicit online learning is considered. A tighter convergence bound is derived, which demonstrates theoretically the feasibility of implicit update for online learning. Then we combine SMD with implicit update technique and the resulting algorithm possesses the inherent stability. Theoretical result is well corroborated by the experiments we performed which also indicate...
