[ns] Need Simulation for WSNs (802.15)

[Mubashir Rehmani]

Hi AMathiew Moussa

Basically SMAC is a MAC Protocol specifically designed for WSNs to conserve
the energy by integrating Active/Sleep Regime. I think you should do this:
1. Include SMAC as your MAC Protocol in your simulation.
2. You can create nodes and assign the status of sink to some nodes and
assign the status of simple sensor nodes to remaining nodes.
3. To enable Hello Messages from sensor to sinks, i suggest you to use AODV
Protocol or create your own function sendHello() in your customized
protocol.
4. To send messages between various sinks, i think you can do this in your
customized protocol (in c++ implementation of ns2).
5. This can also be in done in c++.

This basic thing that i would suggest you it to first decide which framework
you are going to use. For instance you can use directed diffusion or your
own customized routing protocol that is responsible for communication
between sinks to sinks or sensors to sinks.

Hope my answer will help you :-)
