Uplink sum power minimization problem with required Quality of Service (QoS) under statistical Channel State Information (CSI) and probabilistic constraints in solved for a multicell multiuser scenario. To handle the probabilistic constraints and analyze the system performance, financial risk management measures Value at Risk (VaR) and Conditional Value at Risk (CVaR) are applied. The resulting expressions...
This paper presents a bandwidth-negotiation scheduling (BNS) for 802.16j MMR networks. The proposed BNS not only can allocate adequate bandwidth for UGS, rtPS, nrtPS, and BE in sequence of priority levels, but also can invoke negotiation between access and relay zones when the remaining bandwidth is insufficient to meet the minimum bandwidth requirement of rtPS or nrtPS. Besides, our BNS scheme can...
Services with good quality do not always diffuse because consumers cannot confirm the quality of service before purchase because of the nature of service characteristics. Therefore, service diffusion must be studied using computer simulations to clarify the process of acceptance among consumers. This paper presents a multiagent-system-based model for service diffusion among consumer interactions modeled...
Resource selection plays a very important part in grid. To select a resource object which best match the demands of users in grid, this paper proposed a resource selection algorithm based on binary variable. The application of this resource selection algorithm in grid will present a good quality of service (QoS) of resource selection. Experiments show that this algorithm can find the most needed and...
