14.1 Introduction

The main idea of this project was to implement WSNs [ 1 ] in bringing new content
to museum visitors, making the visit more interesting and, thus, attracting more visi-
tors. We created two applications: security application - which uses sensor abili-
ties to monitor exhibit surroundings, and visitor's application - which communicates
[ 2 ] with exhibit sensors and identifies them. Each exhibit is equipped with
SunSPOT device, which continuously broadcasts its address for visitor's applica-
tion to pick up and on regular time-cycle broadcast sensor readings for security
application. Each visitor would receive PDA type of device, which would after
identifying the exhibit, display content for it. The content could be text, audio,
video, or images, depending on the exhibit. Visitor application also displays cur-
rent position on the museum map. Map can be used to guide the visitor through
the museum, either by standard guide tours or if visitor wishes to see certain
exhibits. Exhibit sensors monitor light, temperature, and acceleration. This infor-
mation is broadcasted after fixed period of time (if every reading is within given
range) or immediately, if some of the readings go over the given threshold.
Security officer is presented with the map of the museum, where every exhibit is
displayed with light, temperature, and acceleration readings.

14.2 Current status

At the moment of writing (November 2009), we created both applications -
visitor's and security. They are operational and core functionalities are present.
We based our work on two types of code: Java and C#. Java code is deployed
