Team’s Status Report for 10/01

This past week our team finalized our design for our project. We got our Raspberry Pi and set it up and ordered our STM32’s for each of our nodes. We mainly spent the week figuring out components of our design and working on the design presentation. One of the main tasks completed this week was looking into routing and networking protocols to use. We settled on a combination of spanning tree protocol as a MAC protocol, and time-division to ensure that nodes are transmitting to listening nodes (not in low-power mode). We’re basing our protocol on Koutsonikolas and Salonidis’s paper on TDM MAC Protocol Design and Implementation for Wireless Mesh Networks. However, we’re simplifying the node TX/RX scheduling, and have replaced Dijkstra’s algorithm for creating a tree out of the mesh network to using STP to create a tree, and then using source-routing from the gateway to route packets to the nodes. We’re also currently working on testing the VOC sensor and the temperature sensor to determine whether they can detect the presence of lit match (we will demo the sensor network with this method). We also now have our Raspberry Pi setup and are able to ssh into it to download any software necessary. We are hoping to have the materials we ordered soon to start testing and working on implementation.
