Method of broadcasting packets in ad-hoc network

A method for distributing a broadcast data packet to a plurality of moving nodes comprising the steps of:

• receiving a broadcast data packet containing at least a message, a sender identifier, a location of a sender, an identifier for a first and second relay node and distance from the sender and each of the first and second relay nodes;
• determining if a node receiving the broadcast data packet is either the first or second relay node;
• and
• distributing immediately the broadcast data packet to a plurality of moving nodes if the receiving node is the first or second relay node, the broadcast data packet that is distributed includes an identifier for a successive relay node;
• wherein the receiving node is determined not to be the first or second relay node, the method further comprising:
• waiting a set period of time;
• determining if a broadcast data packet is received from a different sender containing a same message within the period of time;
• and
• distributing the broadcast data packet to a plurality of moving nodes if a broadcast data packet containing the same message is not received within the period of time, the broadcast data packet that is distributed includes an identifier for a successive relay node.
