Quality-of-service (QoS)-guaranteed traffic is of critical importance in real-time multimedia communications. In this paper, a novel approach to systematic cross-layer monitoring, learning, and optimization using artificial neural networks is developed for wireless links with QoS-guaranteed traffic. The proposed method is used to jointly optimize the design parameters of the adaptive modulation and...
In this paper, we have presented an opportunistic multi-server scheduling scheme that distributes traffic on multiple wireless interfaces of a mobile router to improve service guarantees for competing flows during mobility. The proposed adaptive, scalable, multi-server (ASM) scheduling scheme extends guaranteed-rate(GR) service model to ensure bounded service delays for each packet of flows in accordance...
Given a wireless network where some pairs of communication links interfere with each other, we study sufficient conditions for determining whether a given set of minimum bandwidth quality-of-service (QoS) requirements can be satisfied. We are especially interested in algorithms which have low communication overhead and low processing complexity. The interference in the network is modeled using a conflict...
End-to-end Quality of Service (QoS) provisioning in wireless heterogeneous networks require complex resource management and link utilization strategies. One important issue in QoS compliance relates to load-balanced resource management for increased survivability and availability of network services. In this paper, QoS provisioning issue has been addressed with the help of token bucket regulator (TBR)...
We propose a quality-of-service (QoS) driven power and rate adaptation scheme for multichannel communications systems over wireless links. In particular, we use multichannel communications to model either diversity or multiplexing systems, which play a fundamental role in physical-layer evolutions of mobile wireless networks. By integrating information theory with the concept of effective capacity,...
