Currently, information and communication technology (ICT) accounts for 4% of global greenhouse gas (GHG) emissions. Although EU's decarbonization planrequires 40% reduction of GHG emissions by 2030, those evoked by ICT are predicted to increase due to the growing number of mobile devices and wirelessnetwork facilities. In this context, Integrated sensing and communication (ISAC) technology has been gaining attention as a potential solution, enabling thereuse of wireless hardware for both sensing and communication functionalities. While recent progresses of ISAC open up new opportunities for wirelesssystems, co-existence and cooperation of multiple ISAC systems to realize extended wireless networks with reduced power consumption have not beenexplored to date. Therefore, research project aims to design and develop connected sensing techniques (ConSenT), which provide unique opportunities forupcoming ISAC networks. Enhanced sensing capabilities achieved by cooperatively integrating adjacent and/or distributed networks contribute to build powerefficientISAC networks. We set two objectives to deliver ConSenT in different connected sensing scenarios. Non-coherent connected sensing approach allowsmultiple ISAC nodes cooperating by exploiting multi-static reflections. Joint transceiver design of ISAC is explored to establish the foundation of networkedISACs. Also, coherent cooperation of the synchronized ISAC nodes is investigated to achieve the optimal communication and sensing metrics of the multipleISAC nodes. ConSenT approaches focus on developing energy-efficient networks by exploiting interdisciplinary methodologies, including communication andradar signal processing, transmit/receive beamforming optimization, modeling of stochastic geometry, and machine learning.
