Simulation of Wireless Sensor Networks Using TinyOS- A case Study

Implementation of wireless sensor network applications demands a new set of tools to aid the programmers. A number of simulation platforms developed so far provides varying degrees of energy and delay optimization details for understanding the performance of a sensor network. To relate however, none of these schemes have been simulated with one of the most important aspects of sensor application design that of power consumption. We wanted an approach by which a sensor network can be simulated by utilizing motes. In this paper, we present a case study, where each sensor mote broadcast a number between 1 and 7. The mote whose id matches with the number it receives, turns on its Leds to the received signal value. We have used TOSSIM [1], a well known simulator for wireless sensor networks, for our simulation. It can simulate with nesC[8] source code in TinyOS[2] environment, subsequently which may be used for real test bed situation without any significant modifications.
