In a mobile ad hoc network, the behavior of nodes is always characterized by group features, such as group mobility and communication in group. We propose a localized topology control algorithm, named group aware topology control (GATC), which takes the group features into consideration, and improves the connectivity of nodes in the same group. The structure derived from our algorithm, called GAG-f,...
Power control is an essential mechanism for wideband code division multiple access (W-CDMA) systems. In our earlier work, a combined power control and a greedy rate packing (GRP) allocation scheme employing conventional fixed stepsize power control (FSPC) is discussed and evaluated. In this paper, we extend the algorithm to apply a novel dynamic stepsize power control (DSPC) algorithm to improve system...
Power control and rate assignment are important tools to maximize system resource utilization while satisfying quality of service (QoS) in a code division multiple access (CDMA) system. In this paper, we propose an algorithm of simultaneously adapting transmission power and data rate to maximize system throughput and minimize the power consumption in a wideband CDMA (W-CDMA) network. The greedy rate...
