NetMonitor

A healthy network is very important for the assist-living applications to deliver packets in a real-time and reliable fashion. However, in real deployments, communication qualities are 1) time-varying, and 2)  sensitive to physical locations. The goal of this project is to monitor the status of network, identify causes for degraded quality, and improve the network performance autonomously.

NetMonitor assesses the quality of all links in the network and their impact on topology and reliability.  By evaluating various metrics for link quality and studying their patterns of variance in spatial and temporal dimensions, the system preserves communication performance that is vital for safety-critical applications such as in assisted-living and healthcare.
