Mobility model and call admission control (CAC) algorithm are important for wireless mobility networks. This paper firstly sets a practical mobility model, and then presents a novel measurement-based CAC algorithm utilizing time series analysis under the random model. The algorithm updates the reservation threshold by directly forecasting the next possible number of handoff dropping calls, using ARMA...
An autonomous iteration-based approach is proposed to identify faulty links for LEO satellite systems employing intersatellite links (ISLpsilas). A designed network satellite with management responsibilities collects the routing information of communication itself with other satellites, based on which a fault diagnosis model is introduced. Then the most likely faulty link is identified by using an...
Currently, a lot of studies on network fault management have focused on the terrestrial network, which appears to not easily be applied to satellite networks. An autonomous iteration-based algorithm is proposed to identify faulty links for LEO satellite systems employing intersatellite links (ISL's). A designed network satellite with management responsibilities collects the routing information of...
An adaptive threshold-based call admission control (CAC) scheme used in wireless/mobile network for multi-class services is proposed. In the scheme, each class' CAC thresholds are solved through establishing a reward-penalty model which tries to maximize network's revenue in terms of each class's average new call arrival rate and average handoff call arrival rate, the reward or penalty when network...
