N2 - Opportunistic mobile sensor networks manifest profoundly practical values. Its sink nodes have no fixed connection with the source node, which adopt "store-carry-forward" paradigm to transmit data during random meetings. On the circumstance, we propose a novel data collection scheme and a forwarding strategy based on Active Degree (AD). This scheme calculates the AD from each node to all sink nodes based on a definition of expected latency and the concept of entropy. Messages are forwarded according to the AD values in the degrading order during the occasion, until the message reaches the sink node. Simulation experiments reveal that the scheme is able to adapt to networks' dynamic evolution, which is robust, and has low cost of calculation and storage, which is adaptable to sensor nodes with limited resources.
