An interference aware multi-channel MAC protocol for WASN

2017 International Conference on Innovations in Electrical Engineering and Computational Technologies (ICIEECT), 2017
Wireless sensors network is a network consists of sensors node, creating cluster and selection of cluster head is an issue for an efficient WSN. A new technique is proposed in this research which is termed as Wireless Active Sensors Network (WASN). We designed a novel protocol called interference aware Multi channel protocol based on MAC for sensors ...

Spatial Statistical Analysis of Urban Noise Data from a WASN Gathered by an IoT System: Application to a Small City [PDF]

Applied Sciences (Switzerland), 2016
EU Directive 49/2002 and Spanish law 37/2006 urge cities to develop strategic noise maps and action plans to evaluate noise exposure and to establish noise abatement procedures in critical areas. However, noise mapping involves costly and cumbersome measurement procedures that can become a real issue in practice.

Optimization and Evaluation of an Energy-Efficient MAC Protocol for WASNs

2010 Sixth International Conference on Networking and Services, 2010
A Wireless Ad hoc Sensor Network (WASN) is an autonomous collection of low cost devices that communicate over wireless links. This devices are often powered by limited energy resources, and it is expensive and sometimes infeasible to recharge or replace them. Hence, energy efficiency is the main design concern for such a network. In literature, several

Performance analysis of MVDR beamformer in WASN with sampling rate offsets and blind synchronization

2015 23rd European Signal Processing Conference (EUSIPCO), 2015
In wireless acoustic sensor networks (WASNs), sampling rate offsets (SROs) between nodes are inevitable, and recognized as one of the challenges that have to be resolved for a coherent array processing. A simplified free-space propagation is considered with a single desired source impinging a WASNs from the far-field and contaminated by a diffuse noise.

Security in wireless actor & sensor networks (WASN): towards a hierarchical re-keying design

International Conference on Information Technology: Coding and Computing (ITCC'05) - Volume II, 2005
Our work aims to address the challenging security issues in an important information infrastructure - large-scale and low-energy wireless actuator and sensor networks (WASN). Since WASNs have specific network constraints and data transmission requirements compared to general ad hoc networks and other wireless/wired networks, the security issues need to

WASN: WiMax Based ad hoc and Sensor Network Event Monitoring—A Unique Management Architecture

National Academy Science Letters, 2015
The improvement on network operation by monitoring the event status of various facilities has gained attention recently. In this work, a new event correlation and monitoring scheme is proposed based on WiMax network with localized computation and available resources.

I WASN´T LOOKING AT HIS NICE ASS: HOW TO PLAY THE “FEMALE WAY”

2022
This article explores the strategies used by female video game players within the masculine and heteronormative culture of video games and asks whether there is a “female way of playing”. With knowledge of the fact that most avatars are still male, I revisit the concept of the male gaze (Mulvey, 1989) and argue that female players objectify male ...

Tweedsmuir Glacier, Alsek River, and the salmon migration that wasn’t

Sockeye salmon are an important species both ecologically as well as culturally. At some point in the recent geological past, as substantiated by Indigenous oral history and ecological data, sockeye would migrate up Alsek River through the St Elias Mountains into southwest Yukon.
