Data forwarding method for reliable service in sensor networks

摘要

The present invention data which are sent and received between the sink node and the source node in the sensor network is configured to relay the data transmitted from the source node, the source node sending to collect data sink node and the sink node specified by the relay node for transmitting to the sink node quickly determine the error, we propose a way to healing. The relay node is the source node to transfer the data for which it is determined whether the source node is set group, and, when the judgment result of the source node with a data source node transmission is set group, and stores the data in the buffer, to a neighboring node send. That is, by managing the data to a relay node that has a buffer unit without management data prior to the source node and the sink node units can heal the error quickly. ; Sensor network, the sensor node, the sink node, the virtual relay agent, buffer
