Abstract:
1. A method of providing reliable communication between a sender and a receiving peer node, comprising: a. providing a sender; b. providing a plurality of receiving peer nodes; c. providing a broadcast, wireless sender communication link, said sender communication link being capable of broadcasting a message from said sender to each of said plurality of receiving peer nodes which is at a given instant able to receive said message; d. providing a broadcast, peer communication link among said plurality of receiving peer nodes; e. for each message fragment sent over said sender communication link and said peer communication link, assigning a unique identifier that includes the group said message fragment belongs to and a sequence identification; f. broadcasting a plurality of said message fragments from said sender to said plurality of receiving peer nodes over said sender communication link; g. each of said receiving peer nodes evaluating said message fragments received in order to determine a list of missing message fragments; h. for each of said receiving peer nodes which is missing a message fragment, randomly selecting a subset of said list of missing message fragments and broadcasting missing fragment requests corresponding to said selected subset over said peer communication link; i. each of said receiving peer nodes maintaining a network traffic memory including all missing fragment requests sent over said per communication link and all responses thereto; j. each of said receiving peer nodes, upon receiving a missing fragment request, waiting a randomly selected time interval before responding thereto; and k. each of said receiving peer nodes, upon reaching the end of said randomly selected time interval and upon determining that no other receiving peer node has serviced said missing fragment request, responding to said missing fragment request.
