چکیده
In this paper w e study distributed position estimation for sensor net w orks.The fundamentals of distributed position estimation algorithms are presented. Two types of ellipsoid outer-approximation algorithms are employed to estimate the positions of unknown sensors. P olytopeouter-approximation algorithm is also investigated. Numerical experiments demonstrate the e ectiveness of the algorithms. It turns out that polytope type of algorithm is able to yield position estimations more accurately and eÆciently.

A multi-hop PSO based localization algorithm for wireless sensor networks
A sensor network consists of a large number of sensor nodes that are distributed in a large geographic environment to collect data. Localization is one of the key issues in wireless sensor network researches because it is important to determine the location of an event. On the other side, finding the location of a wireless sensor node by the Global Positioning System (GPS) is not appropriate du...
متن کاملTracking performance of incremental LMS algorithm over adaptive distributed sensor networks
in this paper we focus on the tracking performance of incremental adaptive LMS algorithm in an adaptive network. For this reason we consider the unknown weight vector to be a time varying sequence. First we analyze the performance of network in tracking a time varying weight vector and then we explain the estimation of Rayleigh fading channel through a random walk model. Closed form relations a...

Abstract- Tracking a target which is sensed by a collection of randomly deployed, limited-capacity, and short-ranged sensors is a tricky problem and, yet applicable to the empirical world. In this paper, this challenge has been addressed a by introducing a nested algorithm to track a maneuvering target entering the sensor field. In the proposed nested algorithm, different modules are to fulfill...
