摘要：
We consider a system in which status updates are generated by a source node at will and are sent to a destination through a wireless channel. The energy consumption of transmission is linearly proportional to service time, which we modeled to be exponentially distributed. Due to the capacity limit of the battery and the vacancy of energy arrivals before the battery runs out, some of the status updates might possibly fail. We analyzed the Age of Information(AoI) for such a system, and show the efficacy of the system parameters on the AoI.
