| Summary: | 碩士 === 淡江大學 === 資訊工程學系碩士班 === 104 === In Wireless Sensor Network, sensor nodes must operate at a low duty cycle mode in energy restricted sensors environment.
Therefore, the sensor node remained in a dormant state most of the time and only to woke up when communication is needed in energy collected sensor network.
The communication delay time is a new challenge for low duty cycle energy harvesting sensor network applications (for example, tracking and alert).
In this paper, we introduce a delay bound node communication solution in energy harvesting network.First we proposed the "unicast" type of solution to identify the minimum delay time, and then we use "broadcast" approach to shorten the delay time.
Finally, we compare the simulation results of "unicast" and "broadcast" method.
"Broadcast" is better than "unicast" method reduced more delay times.
