current research

Multi-interface multi-channel WMN (Wireless mesh networks) is a key access technology in the next-generation wireless network, and becomes a hot discount wedding dresses subject in current research. One of these important works is improve the throughput capacity. In this paper, we make a depth study of the gateway deployment and the network blog new shirts 2010 topology control for the throughput performance of WMN. Correspondingly, we figure out some schemes to improve this project.In a WMN, the traffic is aggregated at mesh router and most of cheap evening dresses them forwarded towards the internet through gateway. Thus easily leads to a cheap wedding gown dresses bottleneck for network performance at gateway. Aimed to this problem, firstly consider the gateway and mesh router as the alike node equivalently. Then use the logarithm-normal polo shirts distribution model of shadow affect in wireless communication to design a weighted objective function to guarantee the connectivity and coverage of nodes, attained the deployment location of candidate gateway; based of the generated connectivity graph of the network and the constraints of the gateway deployment, consider a heuristic tree-set partition algorithm based on degree/weighted to get a good choice of nodes with high throughput and better connectivity act as gateway configuration.
