Sensor Deployment for Source Localization in Wireless Sensor Network System
نویسنده
چکیده
Source localization is an important task in wireless distributed sensor networking system. One of interest research area is to look for an optimal sensor deployment that can improve the performance of source detection and localization. In this paper, we will present an optimal sensor deployment based on Cramer-Rao Bound analysis for energy based acoustic source localization algorithm. Both theoretical analysis and simulation show that the optimal sensor deployment for this algorithm is to deploy the sensor uniformly and densely in the region where the target may appear. In general, sensors deploying on the straight line should be avoided. Maximum sensor interval is calculated to satisfy the maximum localization estimation error bound under certain confidence level when sensors are uniformly distributed. It has been shown that deploying the sensors densely can get high performance enhancement over price addition.
