Situational awareness is a critical component in a post-disaster recovery operation for assessment of needs and identification of available resources at different parts of a disaster-affected area. This information, in turn, may help the relief agencies to appropriately coordinate, manage and channelize their resources. A major hindrance in developing such global situational awareness is the […]
A novel static external network equivalencing method for protection studies on Iran Transmission Grid
In this paper, a novel static external network reduction appropriate for fault studies and relay coordination in transmission system is proposed. By applying the proposed method to IEEE 14-bus network and Hormozgan Transmission Network, its major advantages, simplicity and accuracy (less than 5% error) have been confirmed in comparison with accurate classic and approximate engineering […]
Wireless Body Area Network (WBAN) has become an important part of the wireless communication world in the past decade leading to the need for efficient antennas for In-, Onand Off-Body links. The design of such antennas depends critically on the understanding of their interaction with the host body, and thus on the propagation of waves […]
This paper addresses the area of heterogeneous wireless relaying vehicular clouds. We devise an advanced vehicular relaying technique for enhanced connectivity in densely populated urban areas. We investigate the performance of a transmission scheme over a Long-Term Evolution-Advanced (LTE-A) network where vehicles act as relaying cooperating terminals for a downlink session between a base station […]
Openflow is a step towards a more flexible data plane. In Openflow-based deployments, packet forwarding model relies on a set of pipelined tables. However, supporting multiple hardware tables is challenging while having serious limitations. In this paper, we investigate a novel approach to packet forwarding design that tailors Openflow forwarding paths according to the underlying […]
The emerging smart utility networks (SUN) provide two-way communications between smart meters and smart appliances to achieve low power usage, low cost and high reliability. Because SUN are composed of dense wireless devices, signal interference between the devices is an inevitable problem. This paper presents a precoder design that can reduce the effects of interference […]
1.4 mA (70 mV) peak-to-peak drive of 1.25 Gb/s frequency modulated laser for WDM coherent access networks
A new laser suitable for access-systems with FM efficiency up to 7 GHz/mA and negligible amplitude modulation is presented. It enables 1.25/2.5 Gb/s operations with extremely low driving signals: 70 mVpk-pk and 250 mVpk-pk respectively.
This paper presents a risk-based advanced distribution network management system (NMS) aimed at maximizing wind energy harvesting while simultaneously managing congestion and voltages. The NMS allows the adoption of multi-minute control cycles so the volume of actions from on-load tap changers (OLTCs) and distributed generation (DG) plants can be reduced while effectively catering for the […]
Relay, power and subchannel allocations for underlay non LOS OFDM-based cognitive networks under interference temperature
In this paper, we consider the case where two communicating cognitive radio users are not near to each other or have no direct line of sight(LOS). Some secondary users don’t need the entire spectrum available to them because of their traffic demand being low. If we are able to use this unused spectrum to relay […]
A Novel En-Route Filtering Scheme Against False Data Injection Attacks in Cyber-Physical Networked Systems
In Cyber-Physical Networked Systems (CPNS), the adversary can inject false measurements into the controller through compromised sensor nodes, which not only threaten the security of the system, but also consume network resources. To deal with this issue, a number of en-route filtering schemes have been designed for wireless sensor networks. However, these schemes either lack […]
