具有分组管理的多路访问策略的信息性能时代

Age of Information Performance of Multiaccess Strategies with Packet Management

Antzela Kosta, Nikolaos Pappas, Anthony Ephremides, Vangelis Angelakis

摘要:

我们考虑一个系统组成的$N$源节点与一个共同的接收机进行通信。每个源节点具有无限容量的缓冲器,以存储以分组形式传输的状态更新形式的输入突发业务,这应该使接收器处的状态信息保持新鲜。等待传输的数据包可以被丢弃,以避免浪费网络资源来传输陈旧的信息。我们调查年龄的信息(AoI)的系统性能下的调度和随机访问。此外,我们提出了分析的AOI与和没有数据包管理在源节点的传输队列,其中作为数据包管理,我们考虑的能力,以取代未服务的数据包在队列中,每当新的到达。最后,我们提供了仿真结果,说明了不同的接入协议的年龄性能的网络操作参数的影响。

英文摘要:

We consider a system consisting of $N$ source nodes communicating with a common receiver. Each source node has a buffer of infinite capacity to store incoming bursty traffic in the form of status updates transmitted in packets, which should maintain the status information at the receiver fresh. Packets waiting for transmission can be discarded to avoid wasting network resources for the transmission of stale information. We investigate the age of information (AoI) performance of the system under scheduled and random access. Moreover, we present analysis of the AoI with and without packet management at the transmission queue of the source nodes, where as packet management we consider the capability to replace unserved packets at the queue whenever newer ones arrive. Finally, we provide simulation results that illustrate the impact of the network operating parameters on the age performance of the different access protocols.
