Full-duplex relaying (FDR) is an efficient technique to serve remote users with low power consumption, however, careful interference suppression is needed to mitigate self interference (SI) and multi-user interference (MUI). When multiple FDRs are employed, inter-relay interference (IRI) emerges and degrades system performance severely by consuming excessive transmit power. In this paper, distributed...
QoS-aware service composition problem has been drawn great attentions in recent years. As an NP-hard problem, high time complexity is inevitable if global optimization algorithms (such as integer programming) were adopted. Researchers applied various evolutionary algorithms to decrease the time complexity by looking for near optimum solution. However, each evolutionary algorithm has two or more parameters...
Through systematic analysis and comparison of the common features of SA (simulation annealing), ES (evolution strategy) and traditional LS (local search) algorithm, a new hybrid strategy of mixing SA, ES with LS, namely HIEA (hybrid intelligent evolutionary algorithm), is proposed in this paper. View as a whole, the hybrid strategy is also an intelligent heuristic searching procedure, but it has some...
