The main study of traditional probability coverage problem in wirelesssensornetworks(WSNs) is aiming at twodimensional space, however, most practical applications of wirelesssensornetwork is placed in a three-dimensional sensornetworks. Therefore, probability model is introduced for three-dimensional WSNs. This paper presents a method that using Voronoi divide to control the Scheduling of the probability model nodes in the target area. Also, a coverage control algorithm based on probability model(PMCCA) is proposed. We verify the effectiveness and the practice of PMCCA algorithm by comparing PMCCA algorithm to another algorithm in simulation experiment.

The traditional Poisson model in the modern data networks have been ineffective and cannot reflect the real flow trend. However, since Hosking discovers the network traffic self-similarity, self-similar models have continued to emerge, this article improved FARIMA model based on time compensation. We put forward a sliding FARIMA model which fixes the time delay of FARIMA model and analyzed the model's application in the anomaly detection of network.

According to the application of range-free measurement for wirelesssensornetworks (WSNs), a novel localization algorithm of nodes in based on iterative centroid estimation is proposed in the paper. First, we derive the centroid of the plane enclosed by the current connected beacon nodes as well as the received signal strength (RSSI) between target and beacon nodes. Then, we replace the farthest beacon node from the target node with the centroid node we derive in order to narrow the area of the plane enclosed by the connected beacon nodes and improve the location accuracy through multiple iterations. Judging from the simulation results, the proposed algorithm presents decent results of all indications and is thus eligible for localization in WSNs.

This paper considers a cognitive wireless powered communicationnetwork (CWPCN) consisting of a cognitive base station (CBS) and a set of secondary users (SUs) sharing spectrum with a primary user (PU). The transmission time is assumed to be divided into two parts, where the CBS transfers energy in the downlink during the first time part, and the SUs use the harvested energy to transmit in the uplink based on the time-division multiple access (TDMA) during the second time part. We investigate the problem for minimizing the average outage probability of the SUs by jointly optimizing the time allocation and the downlink transmit power allocation under the interference power and the transmit power constraints and propose a heuristic algorithm to solve it. Simulations show that the proposed algorithm greatly outperforms the benchmark algorithms.
