The early detection of wildfires with monitoring sensors can improve the effectiveness of fire responders, decreasing the destruction of property and saving lives. However, distributing these sensors across a wide area is an expensive and laborsome task. Furthermore, the cost of the sensors themselves may be high, limiting their practicality […]

We study the problem of survivable Virtual Optical Network (VON) mapping in a flexible grid opticalnetwork with programmable regenerators that are capable of converting spectrum and modulation format. We propose heuristic algorithms to address the problem with the objective of minimizing blocking probability for dynamic VON requests.
Survivable Virtual Optical Network mapping in spectrum and modulation format convertible flexible grid optical networks
We address the problem of identifying the topology of an unknown weighted, directed network of LTI systems stimulated by wide-sense stationary noises of unknown power spectral densities. We propose several reconstruction algorithms by measuring the cross-power spectral densities of the networkresponse to the input noises. The measurements are based on a series of […]
Topology Identification of Directed Dynamical Networks via Power Spectral Analysis
Mobility is regarded as a network transport mechanism for distributing data in many networks. However, many mobility models ignore the fact that peer nodes often carried by people and thus move in group pattern according to some kind of social relation. In this paper, we propose one mobility model based on group behavior […]

We demonstrate how maximum entropy (MaxEnt) allocation strategies can optimally determine links within a flexgrid elastic optical network requiring multiple fiber-pairs to support 100% capacity growth with 34.3% improvement in the uniformity of spectrum allocations.

Wireless communication provides convenience service for mobile devices. Considering different wireless characteristics, e.g., WIFI and 3G/4G, a mobile device user may manually change its wireless connection. For intelligent devices, users hope to keep the cooperative networking to work in background automatically. The paper introduces a new method of triggering cooperative networkingamong portable devices, […]

This paper presents a comparison between two planning approaches to DVB-T2 Single FrequencyNetworks (SFN). The first technique is regarded as theoretical and it is based on theoretical hexagonal lattices, where terrain impact is disregarded, the transmitting power and equivalent height are constant parameters over the entire service area. The second one […]

Echo state neural networks (ESNs) provide an efficient classification technique for spatiotemporal signals. The feedback connections in the ESN topology enable feature extraction of both spatial and temporal components in time series data. This property has been used in several application domains such as image and video analysis, anomaly detection, and speech […]

The problem of transmitting confidential messages in M x K wireless X networks is considered in which each transmitter intends to send one confidential message to every receiver. In particular, the secure degrees of freedom (SDOF) of the considered network are studied based on an artificial noise alignment (ANA) approach, which integrates interference alignment […]
