1 Politecico di Milao Advaced Network Techologies Laboratory Iteret of Thigs Projects

2 Politecico di Milao Advaced Network Techologies Laboratory Geeral Rules

3 Geeral Rules o Gradig 26/30 are assiged based o the writte exam Up to 8 /30 are assiged based o the project o Projects delivery deadlies: Before July. 21, > =1 After July 21, but before Sept 22, > After Sept 22 -> =0 =0.5 o What project to implemet, which OS? You decide (TiyOS recommeded)

4 Geeral Rules o Groups Maximum 2 people per group o Project registratio (MANDATORY) You must choose oe of the projects (or propose a origial oe) by FRIDAY 2 DECEMBER, 2016 Registratio ca be doe usig the olie form available at o IMPORTANT NOTES: Oly the projects registered olie will be cosidered! Registratio is ot bidig (you ca register for a project ad decidig afterwards if deliver it or ot)

5 What to deliver o Complete source code of the project o Self-explaatory log file It should show that your project works Try to be as detailed as possible! o Project Report Max. 3 pages, summarizig your approach Iclude figures, if eeded Do t iclude source code o Project evaluatio: Ratioale ad techical depth of the desig choices Correctess of the source code Orgaizatio ad clarity of the report

6 Politecico di Milao Advaced Network Techologies Laboratory 1. Lightweight publishsubscribe applicatio protocol Up to 8 poits

7 Publish-subscribe protocol o Desig ad implemet a lightweight applicatio protocol similar to MQTT o The, you should test its correct operatio with simulatios o a starshaped etwork topology with 8 cliet odes ad a PAN coordiator (broker)

8 Features You eed to implemet the followig features o Coectio: upo activatio, each ode seds a CONNECT message to the PAN, which replies with a CONNACK. o Subscribe: each ode ca subscribe to at least oe amog these three topics (Temperature, Humidity, Lumiosity) with a SUBSCRIBE message to the PAN, cotaiig: Node ID <Topic, QoS> for each topic (QoS 0 = at most oce, QoS = 1 at least oce). PAN replies with a SUBACK message

9 Features Publish: each ode ca publish data o at most oe topic. Publicatio is performed through a PUBLISH message: o Topic ame o Payload (data, ca be a radom umber) o QoS level The PAN receives the message ad forwards it to all odes subscribed to that topic

10 QoS maagemet For PUBLISH message, the QoS cotrols the trasmissio from a ode to the PAN. o QoS 0: message trasmitted just oce o QoS 1: ode keeps retrasmittig util a PUBACK is received For subscriptios, the PAN coordiator forwards the message received o a topic to all subscriptors usig the QoS logic idepedetly for each ode! o The value specified i the SUBSCRIBE message is used

11 Requiremets o Test your implemetatio i the simulatio eviromet you prefer (TOSSIM or Cooja) o Simulate at least 3 odes subscribig to more tha 1 topic.

12 Politecico di Milao Advaced Network Techologies Laboratory 2. Realistic Data Collectio ad Visualizatio System Up to 6 poits

13 Requiremets o Implemet a data collectio ad visualizatio system usig IoT techologies see durig the lectures o Idetify at least 2 sources of realistic data to be collected, e.g. Temperature of your laptop s processor Amout of memory used Network badwidth used Data from your smartphoe (more difficult )

14 Requiremets o Desig Node-RED flows to collect data ad store it somewhere, e.g.: File Database Cloud o Itegrate your flows with at least 2 opesource IoT services, e.g.: ThigSpeak FreeBoard Amazo AWS (trial) o The use of platforms ot see durig lectures is cosidered a plus

15 Requiremets o Log data for at least three days. o After that, build a Node-RED flow to read the data you have collected ad produce a report with daily average, miimum ad maximum. o The report should be trasmitted remotely via Node-RED blocks (e.g., , twitter, facebook, sms?)

16 Politecico di Milao Advaced Network Techologies Laboratory 2. Realistic Data Collectio ad Visualizatio System with TelosB! Up to 7 poits

17 Requiremets o Same as before, but the data should be collected usig a TelosB sesor ode (provided by us). o Availability is limited to 10 TelosB sesors o a first-come first-served basis.

18 Politecico di Milao Advaced Network Techologies Laboratory 3. Data collectio with Thigspeak Up to 4 poits

19 Requiremets o You are required to implemet a system for data collectio usig TiyOS, Node-RED ad Thigspeak o Create 2 WSN, each oe with 1 sik ode ad 2 sesor odes (temperature ad humidity sesors) o You ca use the provided TempHumSesorC.c compoet o Let s see a example

20 Requiremets o Simulate the two WSN i Cooka attachig EACH sik ode to a Node- RED socket o Use Node-RED to trasmit the data to ThigSpeak. Each WSN should be liked to a chael ad each sesor ode should be logged o a differet Field

21 Requiremets o Use Node-RED to read data from ThigSpeak ad write a fuctio to sed a alert whe the average value of the Temperature of the two WSNs exceed a predefied threshold
