Providing quality of service (QoS) assurances in a mobile ad hoc network (MANET) is difficult due to node mobility, contention for channel access, a lack of centralized co-ordination, and the unreliable nature of the wireless channel. A QoS-aware routing (QAR) protocol and an admission control (AC) protocol are two of the most important components of a system attempting to provide QoS guarantees in...
Wireless mesh networks (WMNs) are comprised of nodes with multiple radio interfaces and provide broadband residential internet access or connectivity to temporal events. Our goal is to simplify the network deployment of such a mesh network, and towards that we are presenting procedures for automatic configuration and optimisation of the network. We first present an architecture framework that supports...
This paper presents a Model of Quality of Service (QoS) for Next Generation Networks (NGN), that consist of a tower of five defined layers such as the Model Layer of QoS, Control of Admission, QoS in the Routing, QoS in the Signaling, and MAC QoS. In addition, the model raises a method based on the concept of segregation of functions defining two functional networks along with the tasks of QoS. Then,...
Wireless Mesh Networks (WMNs) is a promising key technology for next generation wireless backhauling that is expected to support various types of applications with different quality-of-service (QoS) demands. Advanced antenna techniques, novel scheduling algorithms and routing schemes have attracted increased research interests aiming to optimize the performance of WMNs and satisfy their vast and diverse...
Wireless mesh networks (WMNs) is a promising key technology for next generation wireless backhauling that have recently attracted both the academic and industrial interest. Such networks are expected to have high throughput demands and support various types of applications with different quality-of-service (QoS) constraints. Opportunistic scheduling has been proven highly beneficial in such networks...
Recent technological advances have enabled SDRs to switch from one frequency band to another at minimum cost, thereby making dynamic multi-band access and sharing possible. On the other hand, recent advances in signal processing combined with those in antenna technology provide MIMO capabilities, thereby creating opportunities for enhancing the throughput of wireless networks. Both SDRs and MIMO together...
