Measuring the location of bio-sensing sensors

Abstract

In recent years, the wireless sensor network is getting more and more popular and applied into many applications. Depending on different requirements, people usually use more than one sensor in their application, since the sensor is cheap, low power consuming and easy to carry. Besides, most applications require to identify the positions of sensor nodes to locate where the events occur. There are already many existing methodologies which can locate the accurate position of sensors. However, their algorithms are complicated and take more computing power which means more energy consumption. In some situations, we simply need rough position. For example, in our bio-sensing project, we only need to know in which sickroom the patient stays. Received signal strength indicator (RSSI) is widely used to locate positions. Nevertheless, the methodology which uses only single one RSSI to determine the position may get incorrect position since the RSSI is easy to be interfered by the environment. In this paper, we propose a methodology to improve this problem by using the redundant packet with dynamic power level. Our experiment results show that the proposed methodology has better performance.
