Development and demonstration of 3-D localization for wireless sensor network

Abstract

Taking advantage of wireless sensor network (WSN) to get the location of forest fire

has attracted a lot of research interest. Because it is a cheap, convenient and power

saving way to realize the communications between sensor nodes and PC. Besides, the

devices needed are light and small, which provides convenience in the test of the

localization algorithm.

The main purpose of the project is to get the estimated distance between target node

and each anchor, which is measured by hops. To get hop counts data, messages need to

be broadcast in the network, which can be realized by using Crossbow Micaz Motes.

And the main difference between the earlier project is that it is a 3D localization

technique, which is more accurate comparatively.

With the help of Micaz motes, hop counts information can be collected. Besides that,

nesC program and MATLAB simulation are also necessary, which can show users the

detailed location of object in a more visual way. And the results of experiments

identify the feasibility of the proposed localization algorithm, which can be applied in

the real world.
