This paper investigates the energy efficiency (EE) of distributed antenna system (DAS) with continuous-rate adaptive modulation (CAM) under different quality of service requirements, and develops adaptive power allocation (PA) schemes for DAS. Firstly, the EE for DAS with CAM is presented. By maximizing the EE subject to the maximum transmit power, target bit error rate (BER), and minimum spectral...
In this paper, we investigate call admission control (CAC) with opportunistic scheduling and propose a novel CAC algorithm for users with quality of service (QoS) requirements. Our main contribution is threefold. First, we verify that, compared with several other scheduling schemes, cumulative distributed function based scheduling (CS) makes the best tradeoff between efficiency and fairness in full-load...
In this letter, we investigate call admission control (CAC) for cumulative rate distribution based scheduling (CS) in wireless communication networks. We first analyze the multi-user diversity gain (MDG) of CS, which is applicable to general channel conditions. Then we propose the minimum rate guaranteed CS/ORR based CAC algorithm, COCAC, which jointly uses CS and opportunistic round robin (ORR) for...
One of the major problems of deploying RSVP in the mobile environment is called the advanceresourcereservation problem. If an RSVP reservation path is reserved in advance in the subnet that a mobile node will visit, the mobile node can continue its QoS session smoothly when it hands over to that subnet. However, if too many network resources are used for advance reservation, new QoS sessions originating...
