Future large-scale sensor network deployments will be tiered, with the motes providing dense sensing and a higher tier of 32-bit master nodes with more powerful radios providing increased overall network capacity. In this paper, we describe a functional architecture for wireless sensor networks that leverages this structure to simplify the overall system. Our Tenet architecture has the nice pro...

Stationary bifurcations in several nonlinear models of fluid conveying pipes fixed at both ends are analyzed with the use of Lyapunov-Schmidt reduction and singular-ity theory. Influence of gravitational force, curvature and vertical elastic support on various properties of bifurcating solutions are investigated. In particular the conditions for occurrence of supercritical and subcritical bifur...

This demonstration shows a powerful high-level, heterogeneous sensor networking framework, Cascades. We intend to demonstrate how, with this framework, application designers have great control over implementation designs without the requirement of indepth development. Several key components and example applications will be demonstrated, along with some important concepts used in this Python-bas...

With the recent advances in wireless sensor technologies, sensor networks have been used in many applications. One of the applications is subject monitoring and tracking, where the locations of the monitored objects are quite sensitive and need to be protected. So event source anonymity is an attractive and critical security property. For event source anonymity, the concept of source location p...

Functional 2D material-based devices are likely subjected to high ambient temperatures when integrated into miniaturized circuits for practical applications, which may induce irreversible structural changes in materials and impact the device performance. However, majority of devices’ studies focus on room temperature or low-temperature operation conditions. Here, high-temperature (up 673 K) ele...

In this paper, we present AmICA: a flexible, compact, easyto-program, and low-power WSN platform. Developed from scratch and including a node, a basic communication protocol, and a debugging toolkit, it assists in a user-friendly rapid application development. Our analysis shows that AmICA nodes are 67% smaller than BTnodes, have five times more sensors than Mica2Dot and consume 72% less energy...
