Abstract:
In this paper, we describe a peer-to-peer communication model for a mobile telecare service. It is proposed
to reduce the service management costs of a conventional mobile telecare service based on a server-client
communication model. The peer-to-peer mobile telecare service consists of a mobile physiological sensor,
two smartphones, and a connection management server. In the service, when a caregiver, e.g., family member,
requires to know current physiological statuses of a cared person, e.g., elderly person, the smartphone directly
sends the sensing data of the cared person to the caregiver’s smartphone without a central data server. To realize
the peer-to-peer communication model in mobile phone’s infrastructure, which includes private networks, we
propose a communication protocol based on a NAT-traversal technique and a data compression mechanism
for preventing packet loss. We have confirmed that the prototype system works well on the current mobile
phone’s infrastructure that co
nsists of 4G (LTE) and private networks.
