论文摘要
移动边缘计算(MEC)和无线电源传输是可以帮助实施下一代无线网络的技术,该网络将部署大量计算和能源有限的设备。在这封信中,我们考虑了一个点对点MEC系统,该设备从接入点的(AP)传输信号中收集能量,以为任务的卸载和/或局部计算供电。通过考虑到能量收集的非线性,我们为成功计算的概率和成功计算的平均数量提供了分析表达式。我们的结果表明,部分卸载和本地计算的混合方案并不总是有效的。特别是,决定在本地卸载和/或计算的决定取决于系统的参数,例如到达AP的距离以及需要计算的位数。
Mobile-edge computing (MEC) and wireless power transfer are technologies that can assist in the implementation of next generation wireless networks, which will deploy a large number of computational and energy limited devices. In this letter, we consider a point-to-point MEC system, where the device harvests energy from the access point's (AP's) transmitted signal to power the offloading and/or the local computation of a task. By taking into account the non-linearities of energy harvesting, we provide analytical expressions for the probability of successful computation and for the average number of successfully computed bits. Our results show that a hybrid scheme of partial offloading and local computation is not always efficient. In particular, the decision to offload and/or compute locally, depends on the system's parameters such as the distance to the AP and the number of bits that need to be computed.
