Ubiquitous wireless infrastructure for elderly care

Monitoring and ensuring the well being of elderly citizen has become an important part of our social care network. Many technologies have been successfully deployed for collecting vital health statistics of elderly and disabled people. We propose a hierarchical pervasive wireless infrastructure for in home care of elderly people. The core wireless sensor network is based on inexpensive transceivers operating in 915 MHz ISM band The connectivity with the monitoring and response centers is deployed using redundant range WiMAX links along with redundant multihop WiFi network. Successful test deployment has shown feasibility of this methodology in many areas beyond in home care of elderly and disables.
