Claim 7:
8. A system configured for multicast communication over an IP network between motes, comprising:
a router having a processor including one or more cores, and a memory;
wherein a first mote is configured to receive a packet, and transmit the packet to one or more recipients using a link layer broadcast transmission;
wherein, if the packet is not received by the one or more recipients, the first mote compares a number of transmissions of the packet with a preset integer, wherein the preset integer represents a number of retransmission timeslots;
wherein, if the number of transmissions of the packet is less than the preset integer, the first mote is further configured to retransmit the packet to the one or more recipients using the link layer broadcast transmission until the total number of retransmissions of the packet to the one or more recipients equals the preset integer;
a second mote, being one of the one or more recipients, which received the transmitted packet using the link layer broadcast transmission, configured to receive the packet from the first mote, and upon receipt, scheduling any remaining timeslots for receiving retransmission of the packet to a sleep mode.
