The main challenges in efficient ISAC are constituted by its limited sensing and communication (S&C) coverage as well as severe inter-cell interference. Network-level ISAC relying on multi-cell cooperation is capable of effectively expanding both the S&C coverage, and of providing extra degrees of freedom (DoF) for realizing increased integration gains between S&C. In this work, we provide new considerations for ISAC networks, including new metrics, the optimization of the DoF, and cooperation regimes, and we highlight new S&C trade-offs. Then, we discuss a suite of cooperative S&C architectures, both at the task, as well as, data and signal levels. Furthermore, the interplay between S&C at the network level is investigated, and promising research directions are outlined. date: 2024-10-22 date_type: published official_url: https://doi.org/10.1109/MWC.008.2400151 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2333168 doi: 10.1109/MWC.008.2400151 lyricists_name: Meng, Kaitao lyricists_name: Masouros, Christos lyricists_id: KMENG45 lyricists_id: CMASO14 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner full_text_status: public publication: IEEE Wireless Communications citation: Meng, K; Masouros, C; Petropulu, AP; Hanzo, L; (2024) Cooperative ISAC Networks: Opportunities and Challenges.
