Abstract

The invention discloses an energy-saving route setup and power distribution method in a wireless multi-hop relay network in the technical field of network communication. The energy-saving route setup and power distribution method comprises the following steps of: firstly, randomly setting up an initialized route; updating a pheromone in the initialized route during a setup procedure; secondly, setting up a route on the basis through a setup method, and updating a pheromone in the route; obtaining an optimal route according to the pheromone in the route, and updating a specific parameter of the setup method; and repeating the steps for set time to obtain an optimal route which is a final route. According to the energy-saving route setup and power distribution method disclosed by the invention, by comprehensively considering network node residual energy, limited node transmitting power, inter-nodal interference and link transmission rate, the network throughput and the energy service efficiency are comprehensively optimized, so that a route algorithm can more adaptive to the changeful environment of the wireless multi-hop relay network, and meanwhile, the goal that energy is saved for the network is achieved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an energy-saving routing and power distribution method in a wireless multi-hop relay network. Background technique [0002] With the rapid development of wireless multi-hop relay network, its application scope is getting wider and wider. The wireless multi-hop relay network refers to a specific network structure, which has the characteristics of distributed control, self-organization, and no center. And because the transmission range of wireless multi-hop relay network nodes is limited, the source node needs the assistance of other relay nodes when sending data to the destination node. For a long time, the focus and difficulty of wireless multi-hop relay network research mainly exist in the routing protocol In terms of design, it is also the focus of wireless multi-hop relay network design. After years of research, wireless multi-hop relay network routing protocol...
