ITEM, TinyOS module for sensor networks

Author: Pavel Beneš

Bakalářské práce 2008

The main aim of this thesis is modification of the existing ITEM software module for the TinyOS 2.0 operating system. It is a module for wireless sensor networks, which implements the E-ASAP (Extended-Adaptive Slot Assignment) and TDMA (Time Division Multiple Access) protocols. These protocols ensure that the module is able to react to network structure changes and improve channel utilization. The first version of the module, which was developed for the TinyOS 1.x operating system, concists of several smaller modules. Each of those modules has its own specific function. These modules are independent on each other and that is why it is possible to modify each module separately. The new version of the ITEM module was tested on a simple application.
