摘要: With the rapid development of Internet Things (IoT) and wide acceptance 4G/5G network, more devices are connected to internet. In this environment, cloud computing meets critical challenges such as high latency huge load. Therefore, researchers introduce edge make up shortage apply idea many scenarios. This paper applies emergency rescue which has a requirement latency. Firstly, we present an edge-based architecture for rescue, includes three layers: Cloud Layer, Edge Layer Device Access Layer. And completion task needs cooperation between layers. Moreover, list some necessary parts in every layer. aiming at mobile device access layer, performer rescuer, wireless vehicles, research QoS-oriented multi-devices selection problem composite services. We algorithm (MDSA) compare it with traditional allocation algorithm. The simulation result shows MDSA good performance aspect packet loss energy consumption.
