Team’s Status Report for 11/19

This week we had further code reviews to familiarize each other with every individual member’s code, as integration between individual parts is starting. We met with the professor and TA about how we would reset all the nodes in the network and how to approach that. Through our discussions, we agreed to synchronize all nodes at the onset by resetting them all at once. If a node were to drop offline, a wildland forest fighter would be able to bring the node online (after having repaired it) at a specific time interval with a 3-5 second margin. We also discussed concerns about integrating our individual parts of the project. The schedule for each of the nodes has been created and includes the receiving and transmitting nodes as well as the order with which the nodes receive the schedule. Essentially, phase 3 of the networking protocol stack has been completed, and the RX/TX schedule is now transmitted throughout the WSN. We are able to synchronize time using a hard-coded time value, that each node’s internal clock will reach simultaneously because they were all reset at the same time. Hence, each node will begin executing the schedule (Phase 4) at the same time. The code for nodes to execute a given schedule is still in progress. Collectively, we hope to test our entire protocol stack on all 8 sensor nodes and the GW running on the RPI by the end of next week.
