Cooperation plays the crucial role in shared space of the homecare processes.It is a rather hard task to ensure effective cooperation in home care environment.This is due to variability of schedules,tasks and mobility of both patients and carers.In this paper,we discuss sensor network technology that can facilitate and improve home care cooperation scenarios.We present methodology,recommendations and applications for incorporating a WSN based solution in various areas of Homecare.We argue that even the most difficult areas of cooperation between patients and their carers such as: information retrieval,information dissemination,scheduling,coordination of short and long-term treatment can be supported by WSN based solutions.Finally,we discuss sensor network design approaches for incorporating smart communication devices and sensors to support health care workers and their patients in their daily activities.The network of smart sensors can help to maintain awareness of the activities of all stakeholders and the need to integrate communication and computer technology with the requirements of effective aged care infrastructure.
