METHOD AND SYSTEM FOR DATA FORWARDING IN DUTY-CYCLED WIRELESS SENSOR NETWORKS

摘要

PURPOSE: By putting in tune the necessary delay to decide the translation distance and receiving node of data packet data communications method and system of the duty cycle wireless sensor network select the most favorable node. CONSTITUTION: A source node having transmission data packet consecutively transmits a message a plurality of preambles shorting than the operational range of the receiving node. The receiving node receiving a message preamble transmits an acknowledge(ACK) to the source node. The source node receives a message ACK. Compensation is presently calculated of the case of transmitting data packet with the receiving node. The prediction compensation of the case of not transmitting data packet with the receiving node and waiting the other receiving node is calculated.
