The design of wireless telecommunications networks is a complex process, which requires solving simultaneously many difficult combinatorial optimization problems. We propose a taboo-search approach dedicated to one of the aforementioned design optimization problems, namely the cell assignment problem. Our approach defines a series of moves applicable to an(More)
The “explosive growth in bursty traffic” changes the network dynamics and requires a good evaluation of various classes of service when designing an access network. From a topological standpoint, the multiservice networks in this paper are heterogeneous systems which integrate both a core and some wireless access networks into an infrastructure similar to(More)
In statistical admission control based on effective bandwidth, the network provides probabilistic guarantees for the packet loss and delay. In integrated multiservice networks like third-generation mobile networks, some traffic classes also need guarantees on the jitter. One approach is to treat jitter like delay. This letter proposes a new criterion to(More)
The problem of assigning of cells to switches in a cellular network is a Ne-hard problem which cannot be solved in an exact way in reasonable calculating times. In this article, we propose a compromise based on the tabu search heuristics to obtain acceptable solutions with little processing effort. The method essentially consists in modifying in an(More)
This paper analyses the pricing framework of multiservice networks and proposes an improved pricing scheme based on the effective bandwidth concept for taking into account quality of service parameters. Based on the deficiencies noted in the classical effective bandwidth scheme (intolerance to user uncertainty and no guarantee on jitter), we propose an(More)
