Energy Efficient Cooperative Sleep Control Using Small Cell for Wireless Networks
Published 2015-08-01“…This paper has two main contributions: first of all, we propose a semistatic energy efficient method to find out the optimal on-off pattern considering the interference from adjacent base stations using integer convex optimization, from which the optimal on-off proportion of base stations could be obtained; then we propose a novel energy efficient cooperative heuristic algorithm in dynamic scenario, by separating the waiting time into two independent Markov processes using the new method; the total power consumption could be reduced significantly by adopting the novel method. …”

Capacity Estimation for On-Ramp Merging Section of Urban Expressway Based on Time Headway Loss
Published 2014-01-01“…Survey data were collected from on-ramp merging sections of shanghai urban expressway system and showed that capacity drop of on-ramp merging section is caused by drivers’ lane-changing which may lead to unsteady speed of vehicles and so prolonged time headway compared to the minimum time headway corresponding to the maximum capacity. Three parameters (optimal time headway, time headway loss, and interference quantity of lane-changing) are given and a methodology by accumulating time headway loss due to lane-changing is developed to estimate the capacity drop. …”

Power Allocation Based on Relay Location and PU Location for CR Network
Published 2015-08-01“…A new transmission mechanism called direct and relay-aided transmissions based on inter group cooperation was proposed for the cognitive radio network.The performance of a single-relay system based on amplify-forward in the Rayleigh fading environment by considering the interference constraints and peak power constraints was analyzed.The impact of the relay node and the primary users(PU)location on power allocation and system throughout was investigated and the performance of the optimal power allocation(OPA)scheme and equal power allocation(EPA)scheme was compared.The result shows that the locations of relay node and PU are crucial to the system performance and the proposal optimum power allocation scheme significantly outperforms the equal power allocation scheme.The best performance was achieved when the relay is at an equal distance from the sender and the destination in EPA scheme or the relay is closer to the destination around in OPA scheme.…”

Performance Analysis of Cognitive Radio System Based on Outage Probability of Cognitive Transmission
Published 2013-10-01“…It is an important part to design an optimal spectrum sensing and transmission framework in cognitive radio network.Considering that cognitive data transmission outage had effect on the performance of cognitive radio system,a novel spectrum sensing and transmission model based on the outage probability of cognitive transmission was proposed and the two phases of spectrum sensing and data transmission were jointly optimized.The model was formulated as a nonconvex optimization problem under the constraint of interference to primary user,which maximized the average achievable throughput by the joint optimization of sensing time and data transmission rate and simulated by means of the numerical method.The numerical analysis shows that a better tradeoff can be achieved among the protection of primary user,the throughput of cognitive system and transmission delay when the outage probability is cited and the constraint is satisfied.…”

Routing approach based on local topology control in cognitive radio networks
