With the recent technological advances in wireless communications, integrated digital circuits, and micro electro mechanical systems (MEMS); development of wireless sensor networks has been enabled and become dramatically feasible. Wireless sensor networks (WSNs) are large networks made of a numerous number of sensor nodes with sensing, computation, and(More)
Mobile Internet Protocol (IP) has been developed to maintain permanent IP addresses for mobile users while they are moving from one point to another where the Mobile Terminal (MT) device will have two IP addresses: a static home address and a care-of address which will be changed and re-attached at each point of the movement of the MT. However, a location(More)
Careful examination of packet traces taken from the MBone reveals a significant number of multiple successive packet losses, even though losses are predominantly isolated. This paper presents a method for reducing the number of burst losses by transforming them into single isolated losses. In this method, the first step is to separate critical video(More)
Risk and Vulnerability Analysis (RVA) aims at identifying the weaknesses of the networks that may be exploited to compromise the normal functions, such as service deployment, file system access permissions, applications activations and so on. Autonomic Communication Networks (ACNs) are recently proposed as business-objective driven high-level self-managed(More)
In the face of uncertainties associated with unique collaborative businesses using Telecollaboration (TC) business system, it becomes mandatory for stakeholders to be fully aware of their needs, roles and responsibilities. This paper attempts to exploit the situation where participants’ collaborative outcomes require a specific and serious know-how analysis(More)
Frequent changes caused by IP-connectivity and user-oriented services in Inter-Vehicular Communication Networks (VCNs) set great challenges to construct reliable, secure and fast converged topology formed by trusted mobile nodes and links. In this paper, based on a new metric for network performance called topology convergence and a new ObjectOriented(More)
This paper proposes a self-organizing scheme based on ant metaheuristics to optimize the operation of multiple classes of managed elements on an Operations Support Systems (OSSs) for mobile pervasive communications. Ant metaheuristics are characterized by learning and adaptation capabilities against dynamic environment changes and uncertainties. As an(More)
This paper describes a management paradigm to give effect to autonomic activation, monitoring and control of services or products in the future converged telecommunications networks. It suggests an architecture that places the various management functions into a structure that can then be used to select those functions which may yield to autonomic(More)
