Abstract
Method, apparatus, and computer program product example embodiments enable data distribution in wireless communication networks. In example embodiments, a method comprises receiving a wireless broadcast message including a message ID and an associated distributor address; buffering the received wireless broadcast message and starting an observation window timer for the message if the message ID of the received wireless broadcast message is not stored in a database of message IDs and associated distributor addresses for previously received wireless broadcast messages; calculating a relaying probability for the received wireless broadcast message, based on a number of distributor address entries associated with the message ID in the database, the entries resulting from receiving other wireless broadcast messages having the same message ID during the observation window; transmitting the buffered message following termination of the observation window, based on the calculated relaying probability; and starting a cooling window timer upon termination of the observation window and removing all records containing the message ID from the database following termination of the cooling window.
