The dramatic growth of mobile multimedia communications imposes new requirements on quality-of-service and energy efficiency in wireless networks. In this paper, we study the energy- and spectrum-efficient cooperative communication (ESCC) problem by exploiting the benefits of cooperative communication (CC) for mobile multimedia applications in multi-channel wireless networks.In a static network, it...
In this paper, The Monte Carlo localization algorithm based on RSS is proposed, which calibrate the weights between mobile node and each anchor nodes by using the distance between anchor nodes and mobile nodes measured RSS values. This method avoids the filter conditions of MCL method which makes it impossible to get enough valid samples and resample to bring a large number of calculations. Simulation...
In this paper, a cluster-based data gathering algorithm ECDGA for mobile wireless sensor networks is proposed. Network model includes mobile nodes and fixed nodes. The former constructs cluster by self-organizing according to the distance between the fixed nodes nearby and themselves. The latter selects cluster head in accordance with the residual energy and location of the mobile nodes around, and...
People are paying more and more attention to mobile sensor network now. Establishment of its model is conducive to in-depth analysis of the system. Based on the located information and graph theory, a distributed sensor network model is introduced. Delaunay triangulation used to describe nodes and the relationship between them and their transmission and fusion of information between nodes. And the...
