摘要
The communication ability of sensor network node is limited. When the data arrival rate exceeds maximum transmission rate of the node, packets will queue in node buffer. As a task-based network, the real-time information requirements of events are different for users in the sensor network monitoring area. Aiming at data transmission characteristics of monitoring multiple events with sensor network, we put forward a sensor network data transmission protocol based on event delay constraint. According to the specific application scenario, the event delay constraint is defined. Based on it, the real-time dynamic adjustment method for data packet priority is designed and different service is implemented in the different event information through the bandwidth allocation strategy. Experimental results show that the protocol can well satisfy real-time demand of the users under many events monitoring scenario, so it is suitable for practical application of sensor networks.
