Development and Implementation of a Low Power Wireless Sensor Network
Independent thesis Basic level (professional degree), 20 points / 30 hpStudent thesis
The wish to measure different environmental parameters, in for example office buildings, is getting more and more important in today’s society. Since the sensors should be easily deployed they need to be battery powered and communicate wireless. Furthermore the radio range must be extended because of the limited range on the free frequencies. This is where wireless sensor networks come in and extend the range by relaying the data through other nodes in the network, thereby extending the total range of the network.
The purpose of this thesis work is to develop a protocol for such a wireless sensor network, capable of delivering and relaying sensor data through the nodes of the network.
The protocol has been implemented in hardware also designed in this thesis. Tests of the network have been performed and the results have shown that the network works very well and fulfills all of the requirements. Furthermore the power consumption is only 15% of the required value. This thesis has produced a very good platform to use as a base for further development of a commercial product.
