Wireless Sensor Networks (WSNs) have been a focus for research in recent years. They enable data gathering across a wide range of domains and areas of interest from health service to environment monitoring, security, etc. Sensors are becoming cheaper, and as a result are being deployed in high density, at the same time; users’ requirements…

An Analysis of the Overhead and Energy Consumption in Flooding, Random Walk and Gossip Based Resource Discovery Protocols in MP2P Networks
All major mobile communication architectures are mainly centralized. When the mobile devices are switched on it will search for nearby base station or access point. The content being searched is mostly stored in a centralized directory manner. Peer-to-Peer platform can be one of the best possibilities to overcome the restrictions and resolve issues incurred due…
Distributed Blind Calibration in Lossy Sensor Networks via Output Synchronization
A novel distributed algorithm for blind macrocalibration of large sensor networks is introduced. The algorithm is in the form of a system of gradient-type recursions for estimating parameters of local sensor calibration functions. The method does not require any fusion center. The convergence analysis is based on diagonal dominance of the dynamical systems with block…
Functional Module Analysis for Gene Coexpression Networks with Network Integration
Network has been a general tool for studying the complex interactions between different genes, proteins and other small molecules. Module as a fundamental property of many biological networks has been widely studied and many computational methods have been proposed to identify the modules in an individual network. However, in many cases a single network is…
Sensor Network Tomography: The Revenge of the Detected
A sensor network is deployed to detect the presence of a moving object (a target) in a surveyed region. Sensors make decisions about the presence of the target. Let us assume the target is aware of the detections it has caused, but has no idea which sensor has made which call. Can the target infer…
Architecture of a Fully Pipelined Real-Time Cellular Neural Network Emulator
In this paper, architecture of a Real-Time Cellular Neural Network (CNN) Processor (RTCNNP-v2) is given and the implementation results are discussed. The proposed architecture has a fully pipelined structure, capable of processing full-HD 1080p@60 (1920 × 1080 resolution at 60 Hz frame rate, 124.4 MHz visible pixel rate) video streams, which is implemented on both…
Adaptive TTCM Aided Near-Instantaneously Dynamic Network Coding for Cooperative Cognitive Radio Networks
An Adaptive Dynamic Network Coding (ADNC) scheme conceived for Cooperative Cognitive Radio (CCR) is proposed for devising a novel ADNC-CCR system. The system is designed for supporting communications between multiple Primary Users (PUs) and a common Base Station (BS), where the independent source information is transmitted from the PUs to the BS with the aid…
Near-Optimal Scheme for Cognitive Radio Networks With Heterogeneous Mobile Secondary Users
In this paper, we study the throughput and delay scaling laws for cognitive radio network with static primary users and heterogeneous mobile secondary users coexist in the unit planar region for both without base-station case and with base-station case. The primary network consists of n randomly and uniformly distributed static primary users with higher priority…
Energy Efficient Self-Sustaining Wireless Neighborhood Area Network Design for Smart Grid
Neighborhood area network (NAN) is one of the most important sections in smart grid communications. It connects residential customers as part of a two-way communication infrastructure responsible for transmitting power grid sensing and measuring status, as well as the control messages. In this paper, we propose a cost-effective, flexible, and sustainable NAN design using wireless…
Dynamic Sequence Number Thresholding protocol for detection of blackhole attack in Wireless Sensor Network
The Wireless Sensor Network (WSN) is a distributed wireless micro-electronic-mechanical system which is deployed in hostile environment, has inherent insecure communication medium and resource constraints. This makes security of Wireless Sensor Network challenging. The blackhole attack is a security threat which manipulates sequence number to degrade the performance of the WSN by increasing packet loss.…
