Embodiment

[0107] There are Q nodes in the multi-hop wireless network, and Q is set to 30, 40, 50, 60 and 70 respectively. All nodes are randomly distributed in a square area of ​​15km x 15km. The present invention assumes that the link fading factor α=2, the destination node is from 1 to h, wherein h is much smaller than Q and h is at most 5, that is, there is at most one destination node. The present invention assumes that the received power is a constant value, and the threshold of the signal-to-noise ratio is set to 1. The relevant variable parameters are the network size and the random setting of the destination nodes. The flowchart of the unicast routing method is as follows: Figure 7 As shown, the specific steps are as follows:

[0108] Step 1: Use the MIP algorithm to establish all communication paths with minimum energy consumption between the source node and all destination nodes, that is, to construct a minimum energy consumption multicast tree, such as Figure 8 shown. ...

Abstract

The invention discloses an energy efficiency cooperative multicast routing method for a multi-hop wireless network, belongs to the technical field of routing in the multi-hop wireless network, and particularly relates to the energy efficiency cooperative multicast routing method for the multi-hop wireless network. The method is based on topology control and network node cooperation, is also calledas an energy efficiency multicast routing method based on topology control and cooperation, and improves the multicast performance of the multi-hop wireless network. The invention provides a periodicdormancy network node to reduce the network consumption, thereby improving the network energy efficiency. According to the method, a reasonable periodic dormancy mechanism is provided to enable the network nodes to work alternately, and energy is utilized more effectively on the premise that normal operation of the network is not affected. By combining the dormancy mechanism and a minimum energyconsumption multicast routing algorithm (TPM,) based on topology control, the multicast energy consumption is significantly reduced, and the network energy efficiency is improved. Compared with an existing method, the method has better energy efficiency and performance improvement.

Description

technical field [0001] The invention belongs to the technical field of routing in multi-hop wireless networks, and in particular relates to an energy-efficient cooperative multicast routing method for multi-hop wireless networks. Background technique [0002] With the rapid development of artificial intelligence and big data technologies, various new services are growing exponentially. Carrying such a huge network service demand requires a huge amount of energy in the communication network. Therefore, high energy consumption has seriously affected the performance of communication networks, especially for multi-hop wireless multicast networks with limited node energy, its high energy consumption has directly affected the connectivity and survivability of multi-hop multicast networks. How to build energy-efficient multicast communication for multi-hop wireless networks has become an important issue in the field of current communication networks. Energy-efficient multi-hop mult...
