# Edu-hoc project
* educational platform / framework
* ad-hoc networks, mostly WSN
* focus on ease of use
## Provides:
* study text, examples, video
* exercises, solutions, evaluation
-----
# Motivation - WSN reality
## limited in
* computational power
* memory
* battery power
* price
* ...
-----
# Motivation II. - WSN reality
* hop by hop communication
* specialized OS (performance oriented)
* C dialect (NesC)
## usual tasks are not trivial
* routing
* intruder detection
* key exchange
* ...
-----
# Edu-hoc solution
* Arduino based network
* simple C code
* set of exercises (scenarios)
* Solve scenarios as attacker
* Fix code to prevent such attacks
-----
# Exercises
* currently 5 scenarios
* Each with different objective
### evaluation as percentage of messages
- captured
- delivered
- modified
-----
# Exercises
## 1. Eavesdropping
* unsecured network
* global broadcast from each node
* unique identification of each message
* capture as many messages as possible
-----
# Exercises
## 2. Black hole - routing attack
* network with dynamic routing
* initial phase of route establishment
* prevent as many packets from reaching BS
-----
# Exercises
## 3. Sinkhole - routing attack
* network with dynamic routing
* initial phase of route establishment
* deliver as many modified messages as possible
* capture, modify and send back
* each attacker with unique string to modify messages with
-----
# Exercises
## 4. Jamming
* secured network
* fixed routing
* prevent as many packets from reaching BS
* No way to modify routes etc.
* solution -> Jamming
-----
# Exercises
## 5. Relay attack
* neighbor discovery
* make two nodes neighbors even when they are not.
* evaluation not yet determined
-----
# Infrastructure behind
* automatic deployment for the whole network
* mass configuration, communication with nodes
* scheduled runs of individual scenarios
* web server with evaluation and current network state
-----
