Embodiment Construction

[0044] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0045] figure 1 The ERO algorithm flow chart of invention, as shown in the figure, specifically includes the following steps in this embodiment:

[0046] Input: user task request signaling frame T-REQ frame, number N of service requests to be processed.

[0047] Output: BECON frame containing device coordination node information and offload time slot information.

[0048] 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.

[0049] 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.

[0050] 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 offloading, which belongs to the technical field of optical wireless communication, and specifically includes the following steps: S1: given a user task request message, and performing type marking and initializing network status information; S2: ONU-MPP will The task request message is broadcast to the collaborative nodes including the edge cloud server and neighboring devices; S3: Based on the current user movement information, estimate the location of receiving downlink data; S4: The network energy consumption and the receiving position offset under different collaborative nodes are Based on the selection of cooperative nodes; S5: Execute the EDBA algorithm to configure time slots for FiWi data and offloaded data; S6: Notify the selected cooperative nodes to process offloaded data, and return network resource information. The present invention avoids inefficient network energy consumption and high time delay caused by unloading data, considers the energy consumption cost of node transmission unloading data and the location offset between the data received by the user and the cooperative node to select the cooperative node, and ensures the reduction of network energy consumption. Optimize latency while reducing power consumption.

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...
