The implement of peak and valley time sharing electricity price is the important measure to regulate power load fluctuation and promote load rate. We build a domestic communication network of WIA in customer's home, in order to make air conditioners and the other appliances connect with each other. In order to get reasonable solution of power utilization, we establish a nonlinear mathematical model,...
Aiming to minimize the average call blocking probability while maximize the utilization of system resources, a joint call admission control based on dynamic bandwidth allocation (DBA-JCAC) algorithm is proposed, which can be well applied to the environment of heterogeneous wireless networks. First, proper quality utility functions are built according to the different QoS requirements and characteristics...
Aiming at working out the problem of existing load balancing algorithms that failed to consider the real time performance level of each access network sufficiently, a new load balancing algorithm is proposed in this paper. Firstly, a judgment matrix is constructed by the received signal strength, the remaining available resources and the current business blocking rate of each network. Secondly, the...
Due to the high cost of wireless network test beds, most of initial research work in this field depends on different network simulation tools to verify their effectiveness. Among those simulators, Ns-2 is one of the most widely used one. In this paper, we described different radio propagation models implemented in Ns-2 simulator in detail and applied two-ray ground propagation and rice an fading model...
