Target localization in wireless sensor networks based on received signal strength
We consider the problem of localizing a target taking the help of a set of anchor beacon nodes. A small number of beacon nodes are deployed at known locations in the area. The target can detect a beacon provided it happens to lie within the beacon’s transmission range. Thus, the target obtains a measurement vector containing the readings of the beacons: ‘1’ corresponding to a beacon if it is ab...
متن کاملReceived Signal Strength Indicator - Based Adaptive Localization Algorithm for Indoor Wireless Sensor Networks
Solutions for indoor localization have become more critical with recent advancement in context and location-aware technologies. When wireless sensor network (WSN) used in complex indoor environment, great propagation loss will be caused and it is very difficult to estimate adaptively the location of target nodes when environment changed. In this paper, an indoor adaptive localization algorithm ...
متن کاملSensor models and localization algorithms for sensor networks based on received signal strength
Received signal strength (RSS) can be used in sensor networks as a ranging measurement for positioning and localization applications. This contribution studies the realistic situation where neither the emitted power nor the power law decay exponent be assumed to be known. The application in mind is a rapidly deployed network consisting of a number of sensor nodes with low-bandwidth communicatio...
متن کاملEnergy Analysis of Received Signal Strength Localization in Wireless Sensor Networks
This paper presents an investigation of energy demands during localization of wireless nodes in ad-hoc networks. We focus on the method based on the received signal strength (RSS) to estimate the distances between the nodes. To deal with the uncertainty of this technique, statistical methods are used. It implies more measurement samples to be taken and consequently more energy to be spent. Ther...
متن کاملSecurity based on Received Signal Strength in Localization for Underwater Sensor Networks
Underwater sensor networks are envisioned to enable a broad category of underwater applications such as pollution tracking, offshore exploration, and oil spilling. Such applications require precise location information as otherwise the sensed data might be meaningless. On the other hand, security critical issue as underwater sensor networks are typically deployed in harsh environments. Localiza...
