Most of the Quality of Service (QoS) routing mechanisms involve periodic exchange of global state information which causes communication overheads. Therefore, localised routing is the method to avoid this problem. The network in this technique is inferred by the source nodes using statistics which are collected locally. The main aim of this paper is to present new localised algorithm to avoid some...
Generalized Multi-Protocol Label Switching (GMPLS) based optical networks are viewed as a promising network infrastructure for the next generation network (NGN) development. By pre-configuring the resources of dynamic optical networks, we can reconstruct the physical topology, thus increase the number of direct routes between potentially heavily loaded physical node pairs and optimize the performance...
Quality of service support for MANETs is a challenging task due to dynamic topology and limited resources. The main purpose of QoS routing is to find a feasible path that has sufficient resources to satisfy the constraints. In this paper a novel QoS routing algorithm based on ant colony optimization is proposed. The proposed algorithm uses Ant-like agents to discover and maintain paths, that satisfy...
In distributed virtual environments, e.g., online gaming, collaborative designs and distributed military simulations, interactivity is one of the most important requirements. The users may notice serious degradations in quality of service when interacting in the virtual world if the response from the system is much slower than what they have experienced in real life. In this paper, we consider the...
In an ad hoc network, QoS support is one of the major concerns. Because of the constant changes of available link state and bandwidth information, the limited node power, and the dynamic network topology, it is difficult for routing algorithms to satisfy the QoS requirements of many applications. In recent study, we proposed CEQoS routing algorithm for ad hoc networks. Taking bandwidth as the QoS...
High speed modern communication networks are required to integrate and support multimedia application which requires differentiated quality-of-service (QoS) guarantees. Routing mechanism is a key to success of future communication networking. However, it is often complicated by the notion of guaranteed QoS, which can either be related to time, cost, packet loss or bandwidth requirements. Communication...
This paper will present a novel survivable routing method for circuit switched mesh networks, which aim to guarantee a pre-defined end-to-end availability for each connection. The proposed method is based on the traditional dedicated protection concept. However, the widely installed dedicated path protection often comes up against topological bounds and is not able to guarantee a certain level of...
