REAL-TIME WIRELESS MULTICAST ROUTER |
摘要 |
This invention generally relates to Low-power and Lossy Wireless Networks. The proposed solution takes advantage of the fact that retry mechanism and back-off mechanism are already present in trickle-based algorithms. This way, it is possible to disable the equivalent features present at the MAC level which are the main causes of the large maxima of the fluctuating end-to-end delay. Also, it has been done away with the additional waiting time which comes from the packet waiting in the buffer in the MAC. Therefore, it has been provided a real-time layer with a limited size buffer able to allocate a deadline to a multicast packet and to select packets for transmission or rejection on the basis of the packet deadline. This way, it is kept a tighter hold on the rejection and waiting of the packets. |
