In order to obtain the transient power system measurement information, Wide Area Monitoring Systems (WAMS) should be able to collect Phasor Measurement Unit (PMU) data in a timely manner. Therefore along with the continual deployment of PMUs in Great Britain (GB) transmission system substations, a high performance communications infrastructure is becoming essential with regard to […]
Future-generation wireless networks are increasingly ubiquitous, which allows countless numbers of netizens to create, share and access live video sequences with several content forms and textures. As a result, there emerges a dire need for mechanisms to assess the quality of video transmission. Today’s Mobile Networks are capable of solving many communication problems. However, it […]
Wireless sensor networks (WSN) are used in many fields such as industrial control, building automation, environmental monitoring, etc. IEEE 802.15.4 standard defines the features of MAC layer and physical layer for WSN. Many analytical models studied the performance of the multihop IEEE 802.15.4 networks under the assumption of ideal wireless channel, and they did not […]
In Mobile Ad hoc Networks (MANETs), system performance degrades when some switching nodes and/or communication links fail to operate. As a result, the performability (performance reliability) assessment of MANETs is very important. However, because of the impact of dynamic topology, the traditional system performability analysis methods, such as Dynamic Fault Tree (DFT) and Dynamic Reliability […]
To understand security vulnerabilities of communication protocols used in power systems, a real-time framework can be developed to conduct vulnerability studies. The framework should implement protection mechanisms against vulnerabilities and study their effectiveness. In this paper, a realtime cyber-physical framework or test bed is presented. It integrates a real-time power system simulator and a communication […]
IEEE 802.19.1 is the world first standard that specifies coexistence methods by means of exchanging messages between 802.19.1 coexistence system and wireless systems registered to the coexistence system. We propose a channel allocation mechanism for 802.19.1 management service. The mechanism mainly depends upon channel classification where the CM manages channel availability information based on TV […]
The military communication system is the key element to make a victory in the battle. In general, the combat collaborative communication network is a multi-hop and autonomous system, which is composed by a group of mobile nodes with wireless communication ability. The network has some features such as no center, self-organizing, multi-hop routing and dynamic […]
This paper proposes an improved scheme based on Bandwidth-Efficient Multicast Routing (BEMR) for Mobile Ad Hoc Networks (MANET) to further reduce the control overhead whilst increasing the overall bandwidth efficiency. After carefully studying the original BEMR design, two new approaches are proposed to enhance the BEMR performance. One is in the tree set-up phase, while […]
Traffic engineering is one of the most challenging topics in Multi-protocol Label switching (MPLS) which deal with controlling traffic in such a way so that optimized path can be achieved with respect to network utilization and efficient data delivery. Internet traffic use Interior Gateway Protocol (IGP) to send traffic over the network using the shortest […]
In the Modern Era of computing, The Wireless communication has gained popularity with the passage of time due to unique features, e.g. Flexibility, cost effective and easy to configure as compare to traditional wired networks. Since 1990swireless networks become the backbone of every network and there are lots of concerns in wireless communication, which are […]
