Abstract — Under rubble communication is a well-known difficult problem. This is due to a number of inherent difficulties including plentiful and diverse physical obstacles that challenge both wired and wireless communication. Our previous work has shown that it is possible to use Urban Search and Rescue (USAR) dogs to deliver emergency supplies, robots and surveillance equipment to a patient trapped in rubble. As a continuation of this work, we propose a novel approach for establishing a line of communication between rescuers and trapped victims via a hybrid wired and wireless network. The delivery method utilizes rescue canines to automatically deploy a communication node upon locating a patient. The communication node is a WiFi access point with a tethered connection to an exterior command centre. Our preliminary results demonstrate that it is possible to establish two-way audio and video communication with a simulated patient using a human-delivered tether. Future experiments will test the efficacy of canine delivery.
