A method for efficiently acquiring data from a plurality of proximate devices including a mobile ad-hoc network (manet); selecting one of the mobile devices as a harvest node to transmit data to a repository for storing data; responsive to detecting a first data stream and a second data stream from a respective first mobile device and a second mobile device, determining that the data from the first and second data streams have a threshold similarity; utilizing a node in the manet to compress portions of the first data stream and the second data stream to produce a compressed data stream according to a first compression technique, wherein data from the first data stream and the second data stream are present in the compressed data stream; and transmitting the compressed data stream to the repository by the harvest node.
