— This paper investigates the problem of the formation of an uplink tree structure among the IEEE 802.16j network’s relay stations (RSs) and their serving base station (MR-BS)....
—In a previous paper [4], we described an approach to improve the performance of the M/M/2 system by replacing its homogeneous servers with heterogeneous servers. Denoting by β ...
—When constructing an unstructured P2P topology, one should consider the application running on top of it in order to achieve a good performance for the whole P2P system. It is n...
Target detection and field surveillance are among the most prominent applications of Sensor Networks (SN). The quality of detection achieved by a SN can be quantified by evaluat...
— In this paper, a parallel model of multi-objective genetic algorithm supposing a grid environment is discussed. In this proposed parallel model, we extended master-slave model ...
