-# ANAWS Project
+# NetPP exhibition control wireless sensor network
-Project for Advanced Networks and Wireless Systems exam (Networking++ for friends)
+NetPP is a simulation of a wireless sensor network which makes use of the IEEE stack recommended for IoT, from bottom to top: wireless IEEE 802.15.4, 6LowPAN, IPv6 with RPL routing, UDP and CoAP. It runs on Z1 motes.
+This project was developed for the Advanced Networks and Wireless Systems exam (Networking++ for friends)
 
+## Scenario
+NetPP is a company which organizes public events and exhibitions, which installs a sensor (_oracle_) for each stand in order to keep track of people's flow.
+* Formal requirements:
+  * network must be fully operational in less than 70 minutes, which is an estimation of the time needed to mount all the stands for small daily exhibition
+  * nodes run on battery and must use as less energy as possible, in order to make it possible to reuse them for multiple events
+* Other requirements:
+  * RPL must use objective function 0, ie find the nearest grounded root
+  * Sensor messages must be RFC8428 (SenML) compliant
+  * a CoAP proxy must be developed in Java using the Eclipse Californium CoAP library (_proxy_)
+
+## Trickle parameters
+
+## Repository organization
+* ```client```: source code for a CoAP client
+* ```cooja```: sample simulations for Cooja
+* ```oracle```: source code for the sensor node
+* ```proxy```: source code for the CoAP proxy
+* ```simulation```: scripts for running simulations and plot performance graphs
+
+## Run
+1. choose a Cooja simulation file from ```cooja``` directory
+  - start the serial socket server on node 1 (border router)
+  - start the simulation
+2. attach a _rpl-border-router_ to Cooja
+  - you can use the one from ```examples/ipv6/rpl-border-router``` in your Contiki repository
+    - if you want to reproduce the simulation results, use the modified version (which outputs the number of discovered routes)
+  - connect
+    ```$ make connect-router-cooja PREFIX="2001:db8:cafe:babe::1/64"```
+
+### Proxy
+1. ```$ mvn package```
+2. ```$ java -jar target/proxy-2019.11.0-jar-with-dependencies.jar <prefix> <n>```
+
+where
+  - ```<prefix>``` is your network prefix (specify **all** 64 bits)
+  - ```<n>``` is the number of nodes in the network
+
+Example:
+  ```$ java -jar proxy/target/proxy-2019.11.0-jar-with-dependencies.jar 2001:db8:cafe:babe 30```
+
+Resources on the server are named after the node IPv6 address, eg: ```urn:it.unipi.ing.ce.netpp:c00000001```.
+
+You can use a CoAP browser to list all resources on the server, for example:
+* https://github.com/federicorossifr/node-coap-browser
+* http://coap.me
+
+### Client
+1. ```$ mvn package```
+2. ```java -jar target/client-2019.11.0-jar-with-dependencies.jar <url>```
+
+where
+  ```<url>``` is a CoAP URL
+
+Example:
+  ```$ java -jar target/client-2019.11.0-jar-with-dependencies.jar coap://[2001:db8:cafe:babe::1]/urn:it.unipi.ing.ce.netpp:c00000001```
+
+
+### Simulation
+Use a simulation with a pseudo random number generator enabled, eg. ```simulation-prng.csc```.
