Description

The SaRaT-IWSN project proposes a new generation radio transceiver to be used into at the IWSN communication node, based on an open source hardware and software platform, but particularized in order to ensure the requirements presented above. The hardware platform is an USRP-type one and the entire radio transceiver is designed starting from the GNU-Radio software platform, according to the Software Defined Radio methods. This method of developing the communication nodes will ensure their scalability as well an easier reconfigurability of the entire network. At the end of the project some recommendations will be considered in order to reduce the costs of the transceivers in order to facilitate their future production and their usage in practical applications.

Technical Objective

The main technical objective (TO) of the project is to design, develop and validate a scalable and reconfigurable wireless communications node at experimental model level, able to be integrated into an Instrumental Wireless Sensor Network (IWSN). Due to the special characteristics of this kind of Wireless Sensor Network (WSN), respectively the timing and spatial constrains which make this kind of WSN suitable to be considered as a measurement network, these communication nodes must be scalable and reconfigurable wireless transceivers, able to ensure a reliable communication with timing and variation delay constraints. Moreover, these wireless transceivers must support communication protocols able to ensure the characteristics of network scalability, reconfigurability and communication with timing and delay constraints at the required levels.

Scientific Objectives

The scientific objectives of the project are to ensure a good balance between the IWSN requirements, both at the physical layer and at the network layer, having some technical characteristics.

The first scientific objective (SO1) is to ensure a scalable and reconfigurable configuration of the wireless transceiver at the physical layer.

The second scientific objective (SO2) is to ensure a scalable and reconfigurable architecture of the wireless sensor network (WSN), able to transform it into an Instrumental Wireless Sensor Network (IWSN).

The third scientific objective (SO3) is to develop a set of communication protocols able to transform the network into the desired Instrumental Wireless Sensor Network (IWSN).

The fourth scientific objective (SO4) is to analyse potential applications for such transceivers, as well to demonstrate its capabilities considering one as a possible target.
