Hi,
I am implementing an network layer algorithm using TOSSIM and synchronized timing is one of the essentials for this algorithm. I saw a link for "Timing Synchronization in Sensor Networks" (http://www.ee.ucla.edu/~saurabh/time_synchronization/). As per my understanding, this time sync algorithm uses the MAC layer to time-stamp the data. I want to keep my n/w layer as generic as possible and not depend on any lower layers.
Is there any other way of achieving synchronized timing in the network. I just want to run my simulations on TinyViz, so I was wondering if it would be possible to have 1 node (Base Station) have a specific clock and then all the other sensor nodes read this value from the Base station on bootup.
Or else have a separate data structure for the clock value and have it as a global value to all the nodes so that they have the same clock value.
Or is there any better way? It will be really helpful if you can post your opinions. Thanks.
Regards,
Yogesh.
