3. Goal of a new framework There exists some frameworks (NS2) but:
Network stack oriented
Difficult to test one algorithm
Difficult to extend and to customize
Why we create an other framework?
Everybody in the TCS group use his own program
and spend a lot of time to code it
Some optimizations can be hidden from users
Algorithm orientation
Modularity

4. Functionalities Easy to implement new algorithms A routing algorithm
A localization algorithm
A mix of different algorithms
...
Customizable (different kind of nodes, of topology, ...)
Customizable Performance measurements

5. UML (Simplified)

6. Implementation of a new algorithm
Every new algorithm has to implement one (or two) methods
Example: Routing algorithm needs to implement:
Node chooseNextNode(...) : specify which node the algorithm will select
The configuration file is adapted and can be started.

7. Customization The framework uses a configuration in XML format.
Each element represents an object.
<routing-strategy
CLASS="sensorsim.algorithm.node.routing.WeightedAverageRoutingStrategy">
<parameter NAME="avgWeight" VALUE="1"/>
<parameter NAME="stdWeight" VALUE="1"/>
</routing-strategy>

8. Statistics
Text
Possible to show statistics written in the console or in a file.
Files can be written in CSV, or in other format.
Graphical
Statistics can be viewed in a GUI to help understand the process.
Images can be exported.
Beautiful

11. Optimizations A lot of work has been done on optimizations:
Calculation of the near range neighbor optimized:
default algorithm: more than 20 minutes
our algorithm: less than 10 seconds
Fast probability algorithm
States are available for nodes to avoid evaluating useless nodes (BROKEN, SLEEP, ...)
...

manage different transmission type (laser, radio)
manage the energy consumption (currently unavailable)
implement standard algorithms
