Abstract
File distribution in wireless mesh networks of devices interconnected in the wireless communications network including a gateway device and a remote device. The gateway device may include gateway storage unit with enumerated storage blocks, together forming the file, a transmitter transmitting the enumerated storage blocks from the storage unit. The remote device may include a storage unit with allocated storage block divided into enumerated storage blocks, a first bitmap mapped to the enumerated storage blocks, a receiver receiving an enumerated block and a processing unit for correlating the received enumerated block to a correlated enumerated storage block and correlating an enumerated storage block with a correlated stored bit in the first bitmap, setting the correlated stored bit in the first bitmap, storing the received enumerated block, building a list of missing blocks, and adding to a missing blocks list, and a transmitter transmitting the missing blocks list.
