Localization in wireless sensor networks [PDF]
Proceedings of the 6th international conference on Information processing in sensor networks - IPSN '07, 2007 A fundamental problem in wireless sensor networks is localization -- the determination of the geographical locations of sensors. Most existing localization algorithms were designed to work well either in networks of static sensors or networks in which all sensors are mobile. In this paper, we propose two localization algorithms, MSL and MSL*, that work

International Journal of Distributed Sensor Networks, 2014 In the study of three-dimensional underwater sensor networks, the nodes would produce changes in perception range under the influence of environmental factors and their own hardware. Requesting all nodes completely isomorphic is unrealistic.

Firewalling wireless sensor networks: Security by wireless
2008 33rd IEEE Conference on Local Computer Networks (LCN), 2008 Networked sensors and actuators for purposes from production monitoring and control to home automation are in increasing demand. Until recently, the main focus laid on wired systems, although their deployment requires careful planning and expensive infrastructure that may be difficult to install or modify.

A biologically-inspired approach to designing wireless sensor networks
, 2005 In this paper, we contend that there are significant advantages in treating some classes of sensor networks as biological-like systems-- both in structural design characteristics and in operational processes.

International Journal of Distributed Sensor Networks, 2012 In conventional directional sensor networks, coverage control for each sensor is based on a 2D directional sensing model. However, 2D directional sensing model failed to accurately characterize the actual application scene of image/video sensor networks.

Validating the Sensor Network Calculus by Simulations [PDF]
, 2007 Network Calculus has been proposed and customized as a framework for worst-case analysis in wireless sensor networks (WSNs). It has been demonstrated that this so-called Sensor Network Calculus (SNC) is an effective network dimensioning tool as it allows

Energy-efficient sensing in wireless sensor networks using compressed sensing [PDF]
, 2014 Sensing of the application environment is the main purpose of a wireless sensor network. Most existing energy management strategies and compression techniques assume that the sensing operation consumes significantly less energy than radio transmission ...
