3. (6 points) Consider the static loT network below, with N homogenous nodes, and one sink. The network is expected to sense and report temperature readings from all 16 regions marked below. Each node has a predetermined value hop(i), which is the number of hops from the sink. a. In designing the routing protocol, you need to predict the traffic flows and arrival rates of sensed reports from each node. List three parameters that will impact the amount of data generated, and explain their impact. b. You realize that you will inevitably need to buffer some data at intermediate nodes as they attempt to relay them towards the sink. List and explain 3 parameters that will play a role in determining buffer size at each node. c. Given the topology and regions above, explain how you would designate buffer space across the regions. Would that change if you use a clustered topology? Why?
