Due to the proliferation of Internet of Things (IoT) and application/user demands that challenge communication and computation, edge computing has emerged as the paradigm to bring computing resources closer to users. In this paper, we present Whispering, an analytical model for the migration of services (service offloading) from the cloud to the edge, in order to minimize the completion time of computational tasks offloaded by user devices and improve the utilization of resources. We also empirically investigate the impact of reusing the results of previously executed tasks for the execution of newly received tasks (computation reuse) and propose an adaptive task offloading scheme between edge and cloud. Our evaluation results show that Whispering achieves up to 35% and 97% (when coupled with computation reuse) lower task completion times than cases where tasks are executed exclusively at the edge or the cloud.

由于物联网(IoT)的激增以及挑战通信和计算的应用/用户需求，边缘计算已成为使计算资源更接近用户的范例。在本文中，我们提出了whisper，一个服务迁移(服务卸载)从云到边缘的分析模型，以最大限度地减少由用户设备卸载的计算任务的完成时间并提高资源利用率。我们还实证研究了重用先前执行的任务的结果对执行新接收的任务(计算重用)的影响，并提出了边缘和云之间的自适应任务卸载方案。我们的评估结果表明，与只在边缘或云上执行任务的情况相比，whisper的任务完成时间可降低35%和97%(与计算重用相结合)。

A Comparative Study of Alamouti and Golden Space-Time Block Codes Alamouti空时分组码与Golden空时分组码的比较研究
IEEE International Conference on Communications : [proceedings]. IEEE International Conference on Communications

In this conference paper, we study the BER and FER performance of the best-known space-time block codes: the Alamouti scheme and the Golden code. By way of computer simulations using a channel simulator based on the geometrical one-ring scattering model, we show that, for equal quantity of information transmitted per channel use, the performance of the Alamouti code is clearly superior to that of the Golden code for a distance between collocated antennas that is equal to and smaller than the wavelength of the carrier. The performances become comparable for an antenna separation equal to and larger than the double of the carrier wavelength. This important result was not known from the open literature.
在这篇会议论文中，我们研究了最著名的空时分组码:Alamouti方案和Golden码的误码率和误码率性能。通过使用基于几何单环散射模型的信道模拟器进行计算机模拟，我们表明，对于每个信道传输的信息量相等，当并置天线之间的距离等于或小于载波的波长时，阿拉穆蒂码的性能明显优于金码。当天线间距等于或大于载波波长的两倍时，性能变得相当。这个重要的结果在公开文献中是未知的。

In this paper, we address the geocasting problem for cellular mobile networks. The crucial components to support geocasting services are, the geolocation mechanism, dispersion of the geolocation information, and geocast message routing and delivery. We present a cellular architecture to support geocasting with minimal overhead signaling, subject to the quality of service requirements of the particular geocast applications.
本文主要研究蜂窝移动网络中的地理投影问题。支持地理广播服务的关键组件是地理定位机制、地理定位信息的分散以及地理广播消息的路由和传递。我们提出了一种蜂窝架构，以最小的开销信令支持地理广播，但要满足特定地理广播应用的服务质量要求。
