Wireless sensor network will enable the reliable monitoring of a variety of environments for several application like in military, forest, etc. This paper focus on the communication routing protocol which has impact on network lifetime and scalability. The sensor network lifetime is a function of energy. LEACH (Low-Energy Adaptive Clustering Hierarchy) as routing protocol of sensor network for energy...
Objective long-term health monitoring can improve the clinical management of several medical conditions ranging from cardiopulmonary diseases to motor disorders. In this paper, we present our work toward the development of a home-monitoring system. The system is currently used to monitor patients with Parkinson's disease who experience severe motor fluctuations. Monitoring is achieved using wireless...
Parkinson's disease is a neurodegenerative movement disorder resulting in rigidity, bradykinesia (slowness), tremor and gait disorder. Deep brain stimulation (DBS) of the subthalamic nucleus has been shown to be effective in managing symptoms, but quantitative methods to facilitate the adjustment of the stimulator settings are needed. In this paper, we present preliminary results from a study aimed...
Deep brain stimulation of the subthalamic nucleus (STN DBS) is a surgical procedure used to treat the debilitating symptoms of advanced Parkinson's disease (PD); characterized by tremor, slowness of movement (bradykinesia) and involuntary movement (dyskinesia). The selection of optimal stimulation parameters is based upon subjective and qualitative clinical observations made across several programming...
Replay protection is one of the three vital security attributes, desirable in a link layer security protocol for a wireless sensor network (WSN). Whether to implement replay protection at the link layer or at the application layer, in the WSNs, remains a debatable issue. For, the popular WSN link security framework TinySec does not offer replay protection, whereas MiniSec at the other extreme, implements...
A multi-pinhole collimation device for small animal single photon emission computed tomography (SPECT) uses the gamma camera detectors of a standard clinical SPECT scanner. The collimator and animal bed move independently of the detectors, and therefore their motions must be synchronized. One approach is manual triggering of the SPECT acquisition simultaneously with a programmed motion sequence for...
The goal of this project is to develop wireless sensors and analysis methods to monitor patients with various motor dysfunctions. We are currently targeting two specific applications: facilitating medication titration in patients with Parkinson's disease and assessing motor recovery in stroke survivors undergoing rehabilitation. In our vision, the treatment and rehabilitation hospital of the future...
