u-DailyCare : An investigation on WSN & WBAN based Service and Platform

Goals

To design energy efficient and reliable L2 and L3 communication protocols for WSN & WBAN.
To improve communication reliability by developing dynamic block retransmission scheme.
To deal with coexistence problem by detecting the multi-WBAN environment and adapting transmission parameters.
To develop IEEE 11073 standard-based u-DailyCare system that records and provides recommendations for chronic disease patients.

Methods

Design energy efficient single/multi-radio channel MAC protocol for guaranteeing QoS and handling emergency situation in WBAN.
Provide radio environment aware algorithm for cognitive radio sensor networks to improve the route stability.
Predict channel error level and dynamically control block based retransmission to guarantee energy efficiency and QoS requirement.
Predict multi-WBAN coexistence problems through cross-layer algorithms.
Chronic-disease patients management through interlocking of smart phone and smart TV.
Automatic action information management based on sensor devices and smart TV camera.

Surveys

* will be updated soon

Demonstration

u-DailyCare provides the service to measure user’s blood pressure and blood sugar, and manage the measured data.
u-DailyCare service can operate in a smart phone after turning on the sink node.
The connection between the sink node and smart phone is completed by using u-DailyCare application.
u-DailyCare application shows the measured data after measuring blood pressure/blood sugar.
u-DailyCare application sends the measured data to u-DailyCare server and another acquaintance of user.
The u-Dailycare Server accumulates the data of users.
