Health care monitoring using wireless sensor networks is limited by energy, low bandwidth and small memory storage. In this kind of networks, Packet Delivery Ratio (PDR) is often too low, so it is a challenge to support transmission reliability. In heath care context, heterogeneous nodes are generally used. This paper presents a new approach to improve the transmission reliability with a new multicast...
Health care monitoring is a technique for early detection of many symptoms and illness. As a step forward to ubiquitous monitoring, wireless sensor networks could be a solution for health care monitoring. However, wireless sensor networks do not support heavy load because they have limited energy, short transmission range, low throughput and small memory storage. This paper uses multicast protocols...
