Abstract
In this paper we describe a localization and local communication system which allows situated agents to communicate locally, obtaining at the same time both the range and the bearing of the emitter without the need of any centralized control or any external reference. The system relies on infrared communications with frequency modulation and is composed of two interconnected modules for data and power measurement. Thanks to the open hardware license under which it is released, the research community can easily replicate the system at a low cost and/or adapt it for applications in sensor networks and in robotics.
Highlights
Sensor networks consist of spatially distributed autonomous nodes which collectively monitor the environment and coordinate to resolve specific tasks [1, 2]
Sensor networks are currently used in many civilian application areas such as environment monitoring [3], security systems [4], home automation [5], traffic control [6], medical applications [7] or efficient energy consumption [8]
To carry out these tasks, the nodes must coordinate their activities by exchanging information through a communication system
Summary
Sensor networks consist of spatially distributed autonomous nodes which collectively monitor the environment and coordinate to resolve specific tasks [1, 2]. Sensor networks are currently used in many civilian application areas such as environment monitoring [3], security systems [4], home automation [5], traffic control [6], medical applications [7] or efficient energy consumption [8]. To carry out these tasks, the nodes must coordinate their activities by exchanging information through a communication system. Situated communication refers to interactions in which the physical instantiation of the message contributes to define its semantics [10]
