It is generally accepted that neighboring nodes in financial networks are negatively assorted with respect to the correlation between their degrees. This feature would play an important “damping” role in the market during downturns (periods of distress) since this connectivity pattern between firms lowers the chances of auto-amplifying (the propagation of) distress. In this paper…

PPM demodulation schemes for IEEE 802.15.6 IR-UWB WBAN receivers
The performance evaluation of different PPM demodulation schemes employed in PPM based IR-UWB receivers designed to meet the specifications of the IEEE 802.15.6 Standard are presented. The four different PPM demodulation schemes have been investigated for the demodulation of the standard based transmitted signal specific to the PHY layer. The performance evaluation is carried out…
Enhancing Security and Privacy for Identity-based Batch Verification Scheme in VANET
Vehicular ad hoc network (VANET) can significantly improve the traffic safety and efficiency. The basic idea is to allow vehicles to send traffic information to roadside units (RSUs) or other vehicles. Vehicles have to be prevented from some attacks on their privacy and misuse of their private data. For this reason, the security and privacy…
Dynamic OpenFlow-Based Lightpath Restoration in Elastic Optical Networks on the GENI Testbed
Elastic optical networking (EON), with its flexible use of the optical spectrum, is a promising solution for future metro/core optical networking. For the deployment of EON in a real-operational scenario, the dynamic lightpath restoration, driven by an intelligent control plane, is a necessary network function. Dynamic restoration can restore network services automatically and, thus, greatly…
A comprehensive survey of routing protocols in wireless sensor networks
A wireless sensor network is composed of multifunctional sensor nodes scattered in sensing fields. Wireless sensor networks (WSNs) are widely used in applications like Military, Environmental monitoring, Health (Scanning), Space Exploration, Smart homes, Mechanical stress levels of attached objects, disaster management etc. [30] The transmission of information is a tedious task in WSN due to…
Data-oriented malleable reservation to revitalize spectrum fragments in elastic optical networks
This paper investigates malleable reservation (MR) for data-oriented requests to revitalize spectrum fragments in elastic optical networks. We formulate a mixed integer linear programming model and propose a time-efficient heuristic to solve the MR problem.
A Framework for Evaluating the Best Achievable Performance by Distributed Lifetime-Efficient Routing Schemes in Wireless Sensor Networks
This paper is concerned with energy-efficient routing in wireless sensor networks. Most of the existing routing schemes assign energy-related costs to network links and obtain the shortest paths for the nodes to balance the flowing traffic within the network and increase its lifetime. However, the optimal link cost values and the maximum achievable lifetime are…
Priority-Driven Swapping-Based Scheduling of Aperiodic Real-Time Messages Over EtherCAT Networks
Real-time Ethernet (RTE) technologies are becoming increasingly popular, as they provide high bandwidth and are able to meet the requirements of industrial real-time communications. Among RTE protocols, the EtherCAT standard is suitable for motion control and closed-loop control applications, which require very short cycle times. As EtherCAT was specifically devised for periodic traffic, aperiodic real-time…
Robust Restoration Decision-Making Model for Distribution Networks Based on Information Gap Decision Theory
Service restoration is important in distribution networks following an outage. During the restoration process, the system operating conditions will fluctuate, including variation of the load demand and the output from distributed generators (DGs). These variations are hard to be predicted and the load demands are roughly estimated because of absence of real-time measurements, which can…
A Touch-Communication Framework for Drug Delivery Based on a Transient Microbot System
Recent progress in bioresorbable radio frequency electronics and engineered bacteria has promised the prospect of realizing a transient microbot (TM) system for therapeutic applications. The inorganic or organic miniature robots will dissolve into the human body after completing the required tasks and cause no side-effect. In this paper, we propose a potential architecture of a…
