We describe the initial design, implementation and testing of a wearable sensor system employed for human motion analysis. Our proposed system is part of an ongoing investigation aimed at efficiently timing the self-administration of prescription drugs in Parkinson's disease patients by using wireless sensors to capture distinctive motion patterns that indicate the onset of dyskinesia lapses as the...
As software entities that migrate among nodes, mobile agents (MAs) are able to deliver and execute codes for flexible application re-tasking, local processing, and collaborative signal and information processing. In contrast to the conventional wireless sensor network operations based on the client-server computing model, recent research has shown the efficiency of agent-based data collection and...
We present a simple but effective scheme that leverages the effective packet rate in multi-hop wireless sensor networks (WSN) to forward constrained video feeds. The maximum packet rate observed in multi-hop WSN is seldom realized due to various factors. One limitation is that the implementing hardware may possess only one half-duplex radio interface. Additionally, most data forwarding schemes found...
We present the service directory placement algorithm (SDPA), a directory-placement scheme that leverages the performance of existing service discovery protocols over wireless ad hoc networks. SDPA promotes the deployment of a nomadic service directory, whose current location in the network varies according to the dynamics of service-discovery queries driven by the users' applications and partial knowledge...
