Wireless Sensor Networks (WSNs) is an important field of study as more and more applications are enhancing daily life. The technology trend is to achieve small-sized, cheap, and power efficient sensor nodes, which will make the system reliable and efficient. The Crossbow Technologies MICAz mote is an example used in this paper. Measurements of its propagation characteristics in a realistic envi...

1. Research overview Energy efficiency is the chief concern in sensor networks as they have limited power and it often requires tradeoffs with throughput and latency when designing a medium access control (MAC) protocol. The goal of this research is to maximize energy savings based on sleep mode operation and Transmit Power Control (TPC) to save power in Mote-based sensor networks. Two key obje...

Sensor networks deployed for scientific data acquisition must inspect measurements for faults and events of interest. Doing so is crucial to ensure the relevance and correctness of the collected data. In this work we unify fault and event detection under a general anomaly detection framework. We use machine learning techniques to classify measurements that resemble a training set as normal and ...

1.0 Project Goal Smart Dust motes are self-contained, millimeter-scale sensing and communication platforms for a massively distributed sensor network [61,71]. They will ultimately be around the size of a grain of sand and will contain micro/nano sensors, computational ability, bi-directional wireless communications, and a power supply. There exist endless possibilities for the applications of t...

The UTD mote system (UTMOST) is a low power all purpose platform for wireless sensor nodes (WSN) based on offthe-shelf components. UTMOST offers a number of improved functionalities over previously designed platforms, e.g., energy consumption, wireless reprogramming, processing frequency, and storage capability. This paper details how hardware components are selected and integrated to enable su...

Abstract Stabilization of the 2 H phase MoTe during molecular beam epitaxy (MBE) growth on graphene terminated 6 -SiC(0001) is highly desirable in order to take advantage its promising properties electronic applications. By properly adjusting conditions, direct crystalline has been achieved. In such van der Waals heterostructure, atomically-clean interface between and permits coupling adjacent ...
