Location fingerprint optimization based access point deployment in indoor WLAN localization by Mu ZHOU, Qiao-lin PU, Zeng-shan TIAN

“…A novel access point (AP) deployment approach by optimizing the location fingerprints in indoor WLAN localization was proposed.Firstly,constructing the water-filling optimization model based on the maximum of the Euclidean distance of RSS between every two location fingerprints.Secoudly,after the process of the iterative cross-zero adjustment and discrete adjustment,the nonnegative and discrete weights of candidate AP locations were obtained.Finally,by using the criterion of maximum average weight,the APs,and consequently optimize the location fingerprints were deployed rationally.The experimental results demonstrate that the proposed approach is able to achieve high location fingerprint based localization precision,as well as consume low time overhead involved in the optimal AP location searching.…”

Le régime rentier d’accumulation en Arabie saoudite et son mode de régulation by Adrien Faudot

“…The predominance of oil revenues, combined with socio-political parameters specific to the countries, has led the Petro-monarchy to implement a particular set of economic policies, which are analyzed here as the mode of regulation of the oil-rent-caused growth regime, rather than as gradual attempts to restrict the country’s dependence on oil. The rationalization of the Saudi rentier regime relies heavily on migrant workers and on sovereign wealth funds. …”

Optimization method through topology reconfiguration for mobile underwater wireless sensor networks by Ming HE, Wen-hui LIANG, Qiu-li CHEN, Xi-liang CHEN, Jian CHEN

“…The topology of mobile underwater wireless sensor networks (MUWSN) evolves dynamically with ocean currents,which will have great impact on network performance.To solve this problem,a topology optimization method for MUWSNs is proposed based on topology reconfiguration.Firstly,the proposed method optimizes the coverage rate of MUWSNs by adjusting the location of sensor nodes through simulating fish behaviors.Secondly,to optimize the connectivity of MUWSNs,the proposed method repairs disconnected positions and eliminates key nodes in MUWSN through using redundant nodes.Finally,simulation results verify the rationality and validity of the proposed method.Experimental results show that the algorithm can guarantee the network coverage is maintained at about 97%,connectivity rate above 89%,with lower energy consumption.…”
