摘要：
A dynamic data delivery algorithm is proposed which is composed by data transmission strategy and queue management mechanism. It can be applied to heterogeneous delay tolerant mobile sensor networks. Firstly judge each node whether it can transmit messages directly to the sink; then calculate the node's forward probability at different time. Thereafter the forward probability is calculated based on energy consumption and transmission delay. Each node forwards message by the right method. Queue management obey different survival time and transmission counts of different nodes. Simulations show that this data algorithm has a better effectiveness.
