“…Building upon commercial transceivers, extended management and control functions based on open Linux-based software are identified to achieve high performance in ICARUS environments, based on the smart handling of channel, power/rate, CSMA and EDCA parameters. Spectrum-level functions such as channel selection and power control are supported by cognitive radio techniques [25], aiming at operation with minimum interference and maximum spatial reusability conditions. The use of such cognitive radio features in disaster response networks offers opportunities to adapt communication links to the various changes in the operating environment and thereby enhance the performance of the communication network [26].…”

This chapter describes how the ICARUS communications (COM) team defined, developed and implemented an integrated wireless communication system to ensure an interoperable and dependable networking capability for both human and robotic search and rescue field teams and crisis managers. It starts explaining the analysis of the requirements and the context of the project, the existing solutions and the design of the ICARUS communication system to fulfil all the project needs. Next, it addresses the implementation process of the required networking capabilities, and finally, it explains how the ICARUS communication system and associated tools have been integrated in the overall mission systems and have been validated to provide reliable communications for real-time information sharing during search and rescue operations in hostile conditions.

“…It supports adaptation of transmission parameters (e.g., coding rate, service delivery, channel access type, and transmission power) on per message or flow basis given the QoS requirements, channel conditions, and traffic load. In the ICARUS project under EU-FP7 program [6], this DMR modem is integrated with several other wireless access technologies (e.g., Bluetooth, WiFi, Satellite Service) in such a way that the user simultaneously connect with these technologies and seamlessly move between them [7].…”

“…Provisioning and maintaining this connectivity is necessary to fetch sensor data and control the devices. The DMR narrow-band data capabilities of the MioT for long-range and beyond-line-ofright environments are used to provide a robust long range link for robotic command-and-control and cognitive management- and-control of broadband high data-rate WiFi mesh-networks [7]. The MioT device is also used in another project to develop a NATO narrow-band waveform that uses CPM modulation.…”

“…Commercially available DMR devices, to the best of our knowledge, have fixed transmission parameters in the sense that these parameters cannot be changed seamlessly on the per flow basis. We use the DMR to provide a robust longrange link for robotic command and control and for cognitive management of WiFi mesh-networks in a project for roboticassisted search and rescue operations in disaster areas [6], [7]. Furthermore, with the UWB waveform we implemented an RF-ranging application and herein report preliminary results on that.…”

The rapid progress in electronics, sensing, actuation, signal processing, and communication networking has spurred emergence of new technologies like Internet of Things (IoT). In this paper, we report our work on a multi-function IoT (MioT) platform. The MioT supports multiple wireless waveforms that can be used for long as well as short range and beyondline-of-sight environments and an IEEE 802.15.4 ultra-wide band (UWB) waveform for accurate and precise RF-positioning system in harsh wireless environments, e.g., indoor and industrial environments. With the MioT a library of software APIs are provided to configure different parameters of the device through the USB interface. Besides, USB can also be used to transfer data from host to the MioT and vice-versa. Using the MioT we develop a flexible implementation of the DMR access technology. This implementation is used to provide a robust long-range link for robotic command and control and for cognitive management of WiFi mesh-networks in a project for robotic-assisted search and rescue operations in disaster areas. We also report our preliminary results on RF-ranging based on the UWB waveform.
