Hello All, I am working on smac WITHOUT SLEEP AND LISTEN CYCLES. I had few doubts regarding the implementation in tinyos.
1. The README file says that the only deviation of this case from 802.11 DCF will be its overhearing avoidance (the node sleeps when the neighbors transmit) and message passing. However, in the code, I think the SYNC packets are still being exchanged to determine schedules. Isn't this unnecessary since the nodes can automatically wakeup when their nav fires/becomes zero? Am I overlooking something? 2. The backoff mechanism is different from that in 802.11 (Binary Exponential Backoff (BEB)). On a success where does it decrement to minimum contention window? 3. The SMAC paper says that a protocol similar to 802.11 was designed (without the exponentially inreasing backoff mechanism). Where can I find the code ? It would be of great help if anybody can answer these questions. Thanks. Regards, Subah. _______________________________________________ Tinyos-users mailing list [EMAIL PROTECTED] http://mail.Millennium.Berkeley.EDU/mailman/listinfo/tinyos-users
