摘要：In wireless sensor networks, the main work of nodes is for data collection and transmission. CTP (Collected Tree Protocol) had been widely applied, and proved to be reliable, robust, efficient data collection protocol. Its independent with hardware and the data delivery rate is relatively high, but CTP also has some shortcomings: the protocol only relied on the ETX value of next hop node selection, there need other factors to consider. In the original CTP protocol, the energy consumption of a node with a better ETX value was too fast. It would cause the whole network time decreased quickly. Then, the node with better ETX value may have low package rate, and would affect the delivery rate of the whole networks. This paper was aimed at this two aspects of CTP, based on the original CTP, the probability of selection mechanism was introduced, proposed ACTP, lead the node load equilibrium and improved the delivery rate. Through the experimental data of TelosB nodes in real analysis, we had improved the whole network time and increased the number of successful packets delivery.
