Embodiment Construction

[0045] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0046] figure 1 The ERO algorithm flow chart of invention, as shown in the figure, specifically includes the following steps in this embodiment:

[0047] Input: user task request signaling frame T-REQ frame, number N of service requests to be processed.

[0048] Output: BECON frame containing device coordination node information and offload time slot information.

[0049] S1: The ONU-MPP accepts the service request of the i-th user within the range, and selects a coordination node for it. If i>N, go to S10; otherwise, go to S2.

[0050] S2: The ONU-MPP expands the RTS frame with the user information using its padding / reserved bits, and broadcasts it to the cooperating nodes in the range.

[0051] S3: After receiving the RTS frame, the available cooperative nodes in the network use the CTS frame to reply including remaining energy, location...

Abstract

The invention relates to an energy-saving method for edge cloud unloading, and belongs to the technical field of optical wireless communication. The method specifically comprises the following steps of: S1, giving a user task request message, executing type marking and initializing network state information; s2, broadcasting the task request message to cooperative nodes including an edge cloud server and adjacent equipment by ONU-MPP; s3, estimating a position for receiving downlink data based on the current user movement information; s4, selecting cooperative nodes according to the network energy consumption and the receiving position offset under different cooperative nodes; s5, executing an EDBA algorithm to configure a time slot for FiWi data and unloading data; and S6, notifying the selected cooperative node to process the unloaded data, and returning network resource information. According to the method, low network energy consumption efficiency and relatively high time delay caused by executing unloading data are avoided, the cooperative node is selected by considering the energy consumption cost of transmitting the unloading data by the node and the position offset of the user receiving data and the cooperative node, and the time delay is optimized while the network energy consumption is ensured to be reduced.

Description

technical field [0001] The invention belongs to the technical field of optical wireless communication, and relates to an energy-saving method for edge cloud offloading. Background technique [0002] With the advent of 5G mobile networks and the rapid development of smart devices, it is expected that various machine-centric real-time applications are emerging in every corner of our lives. To unlock its full potential, low-latency communications with ultra-reliable, ultra-responsive, and intelligent network connections are required. In order to meet the above requirements, edge cloud enhanced FiWi network has become the focus of current research. At present, the energy-saving mechanism of edge cloud enhanced FiWi network is usually based on the optimal energy consumption of wireless terminals, which leads to the unguaranteed energy consumption of offloading services to cloud network nodes. And in view of the user's mobility, when the selected collaboration node is far away f...
