A Test Bed for Evaluating the Performance of IoT Networks

The use of smaller, personal IoT networks has increased over the past several years. These devices demand a lot of resources but only have limited access. To establish and sustain a flexible network connection, 6LoWPAN with RPL protocol is commonly used. While RPL provides a low-cost solution for connection, it lacks load balancing mechanisms. Improvements in OF load balancing can be implemented to strengthen network stability. This paper proposes a test bed configuration to show the toll of frequent parent switching on 6LoWPAN. Contiki’s RPL 6LoWPAN software runs on STM32 Nucleo microcontrollers with expansion boards for this test bed. The configuration tests frequency of parent changes and packet loss to demonstrate network instability of different RPL OFs. Tests on MRHOF for RPL were executed to confirm the working configuration. Results, with troubleshooting and improvements, show a working bed. The laid-out configuration provides a means for testing network stability in IoT networks

When Memories Make a Difference: Multimodal Literacy Narratives for Preservice ELA Methods Students

This article examines multimodal literacy narrative projects designed by students in a methods of teaching course for secondary preservice English Language Arts teachers. For the multimodal project, preservice teachers infused written, audio, and visual text using a variety of creative mediums. Through combined theoretical frames, the researcher explores semiotics and preservice teachers’ use of multiliteracies as they shift their conceptions of what it means to compose. Finally, this article explores how the act of reflection through the literacy narrative influences preservice teachers’ notions of teaching composition through a variety of mediums

ESSA Research Brief

Every Student Succeeds Act (ESSA): A Research Brief by Samantha Hope, M.T. (March 2017) The Every Student Succeeds Act (ESSA) is a modified reauthorization of the Elementary and Secondary Education Act of 1965. Signed into law on December 10, 2015, it replaces the No Child Left Behind (NCLB) Act of 2001 and provides federal guidelines for states regarding various topics in education. This research brief offers an overview of the legislation, as well as its proposed timeline for implementation and implications for schools in the state of Virginia

Fallow Futures: A Short Story

What will the future be like? And how will humans live with, within the natural world? As we hear more and more of natural phenomena and land formations that are not only protected but also granted legal rights equivalent to those of humans (recently, the Whanganui River in New Zealand), couldn’t we imagine this trend extending to other-than-humans? Wouldn’t the already-ubiquitous grasses, that cover approximately 40% of the earth’s ice-free terrestrial surface, be a good candidate for such a project? In this piece of speculative fiction, humans and grasses together build a future world
