Here we include three parts of our research:
- A partial coAP implementation with several modifications like mDNS support and periodical multicast coAP discovery request.
- A simple multicast forwarding (SMF) algorithm using classic flooding (the simplest option)
- A script that performs the simulation with several modificable parameters
I'm the only one commitiing so I just do:
git add .
git commit
git push origin master
and
git pull origin master
make all will make the modified modules again
./run is some sort of "wrapper" around waf that runs a simulation and package all the results into a compressed file.
Thats and example about the usage of this script:
./run --routing=0 --verbose=1 --ping=0 --speed=40 --interval=15
We performed several simulations. That's an example of some of them:
// Playing with speed and interval
./run --routing=0 --verbose=1 --ping=0 --speed=40 --interval=15
// Using mcast responses
./run --routing=0 --verbose=1 --mcast=1 --ping=0 --speed=40 --interval=15
// Using mcast responses and pinging the discvovered services, using mdns
./run --routing=0 --verbose=1 --mcast=1 --ping=1 --mdns=1 --speed=40 --interval=15
// Using mcast responses but, without sending cache
./run --routing=0 --verbose=1 --mcast=1 --cache=0 --speed=40 --interval=15
// Using mcast responses with a variable response time (pdp)
./run --routing=0 --verbose=1 --mcast=1 --cache=1 --stime=1 --speed=40 --interval=15
// Using mcast responses with a variable response time (pdp) and with a etag to avoid unnecesary data transmission
./run --routing=0 --verbose=1 --mcast=1 --cache=1 --stime=1 --etag=1 --speed=40 --interval=15
//Sometimes we would like to make experiments shorter to evaluate some aspects of the simulation
./run --routing=0 --verbose=1 --ping=0 --speed=40 --interval=15 --runtime=60
mDNS code is strongly based on @mrdunk code written for esp8255 microcontroller
COAP code is strongly based on @hirotakaser Simple CoAP library for Particle Core and Photon
