Development of network monitoring tools for realtime rich-media (RTRM) applications remains a challenge for both academic and industrial researchers as the complexity of the computational processing varies dynamically. We propose a novel, flexible and cost effective technique which can be implemented in ordinary network environment to monitor QoS parameters such as packet-delay, packet-loss, packet...
For seamless mobility in networks that use Proxy Mobile IPv6, Proxy Fast Mobile IPv6 (PFMIPv6) is being standardized. The predictive handover mode of PFMIPv6 can minimize packet loss by forwarding user data from the old mobile access gateway (MAG) to the new MAG to which the mobile terminal (MT) makes a handover and by buffering the forwarded data at the new MAG until the MT is attached to the new...
We propose QoS-aware mesh deterministic access opportunities (MDAOPs) assignment algorithm for the IEEE 802.11s wireless mesh networks (WMNs). The WMNs can benefit from the mesh deterministic access (MDA) in terms of guaranteeing the QoS of the delay bounded traffic, mitigating the exposed node problem, and providing the fairness among best effort traffic flows. However, it is not considered that...
The residential gateway (RG) is known as the connection box that provides multi-service access to the consumer networks. This work is focused on a multi-residential gateway (MRG) concept, which offers more service provisioning and management capabilities. The QoS support in this context is challenging, as new requirements must be fulfilled regarding such multi-network and multiservice environment...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
In this paper, we introduce a pricing model that ensures efficient resource allocation that provides guaranteed quality of service while maximizing profit in multiservice networks. Specifically, a dynamic allocation policy is examined that relies on online measurements while each service class operates under a probabilistic bound delay constraint. We present a rigorous analysis of the properties of...
