Abstract

We analyze a remote sensing system in the Internet of things, where uncoordinated nodes send status updates to a common receiver to achieve information freshness, quantified through age of information. We consider a finite horizon scheduling over a random multiple access channel, where colliding messages are lost. We show that nodes must adopt a further randomization to deviate from identical schedules and escape collision deadlocks. Moreover, we discuss the impact of feedback availability if, due to, e.g., energy expenditure, it decreases the number of transmission opportunities.

非协调有限地平线接入遥感的信息时代

我们分析了物联网中的遥感系统，在该系统中，非协调节点向共同接收器发送状态更新，以实现信息新鲜度（通过信息年龄量化）。我们考虑了随机多路访问信道上的有限视距调度，在这种情况下，碰撞信息会丢失。我们的研究表明，节点必须进一步随机化，才能偏离相同的调度，摆脱碰撞死锁。此外，我们还讨论了反馈可用性的影响，如果由于能量消耗等原因，反馈可用性会减少传输机会的数量。
