Ad hoc wireless multicast routing

Multicast traffic is encapsulated in unicast packets and transmitted from one multicast network to another network, where it is decapsulated and process as multi ...

Since the shortest frame in 100 Mbit/s lasts 6,72 µs and the sequence number wraps at 65536, the value of twrapMin is 440 ms (At 1 Gbit/s, it is 44 ms). This case is extreme, since no device should send ...
