This paper considers adaptive resource allocation for elastic wireless multimedia services in service-oriented networks. To capture the dynamics of user arrivals and departures, the resource allocation problem for wireless multimedia services is formulated as a Semi-Markov Decision Process (SMDP). An optimal decision is made to maximize the overall system reward and the Quality of Service (QoS) of...
This paper discusses placement of sensor nodes in wireless sensor networks. Since the large number sampling points in sensing range of the sensor, the traditional methods, such as greedy algorithm or linear programming model, do not work well. Thus, we create a new method, the grid-based algorithm. First we determine the number of the selected sensor nodes based on the probability theory. Then an...
