Distributed Localization and Sampling Algorithm for 3-Dimensional Mobile Oceanic Sensor Networks

Last several years have overseen a rapidly growing interest in Oceanic Sensor Networks (OSN in short), which consists of a variable number of sensor nodes working at underwater to monitor particular oceanic environment collaboratively. Compared with the traditional sensor networks, OSN has many additional challenges with acoustic communication environment such as large propagation delay, low communication bandwidth and high packet drop rate. Moreover, OSN belongs to one 3-Dimensional framework networks. Therefore, traditional localization schemes for 2-Dimensional terrestrial sensor networks should be transformed into 3-Dimensional localization problem. In this paper, we proposed a large-scale OSN framework for distributed localization first. And then a distributed range-based localization algorithm designed for 3-Dimensional OSN is illustrated in details. Localization accuracy and localized ratio are two metrics to verify our proposed scheme.
