Route improving method based on AODV (ad hoc on-demand distance vector) and considering delay energy saving

Abstract

The invention discloses a route improving method based on an AODV (ad hoc on-demand distance vector) and considering delay energy saving, relating to a new energy-efficient routing protocol considering a delay effect. The protocol firstly judges whether the residual energy of all nodes in an Ad Hoc network moving at a low speed is less than a threshold gamma; if the residual energy of all nodes is greater than the threshold gamma, the network has sufficient energy, and a path of minimum communication energy consumption needs to be found only; and if the residual energy of more than one node in the network is less than the threshold gamma, some nodes in the network consume energy relatively quickly, and the methods such as dynamic power adjustment, route selection of energy consciousness, broadcast control, passive route updating and the like are comprehensively used to realize uniform consumption of the nodes in the network and prolong the working life of a wireless sensor network.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and is suitable for a low-delay and energy-saving routing improvement strategy of an Ad Hoc network with low-speed movement. Background technique [0002] With the popularity of mobile computing platforms and small wireless devices, Ad Hoc wireless networks have attracted more and more attention because they have no physical location restrictions and can self-organize networks anytime and anywhere. As the application platform of this study of the present invention, the intelligent minefield, Ad Hoc has shown its unique advantages. Due to the variability and uncertainty of the geographical environment, the minefield in the actual war environment puts forward high requirements for the self-organization of the wireless data communication network, and because the battery power supply capacity of the wireless communication node itself is limited, Therefore, on the basis of ensuring the...

Problems solved by technology

In terms of hardware or software design, predecessors have proposed many energy-saving methods suitable for AODV, such as AODVjr, AODVsimplified, adaptive AODV, low-power AODV protocol suitable for low-speed motion networks, etc., but the inventors found that these previous methods The performance of the improved algorithm is not very satisfactory in the intelligent minefield environment, because low energy consumption is often at the expense of sacrificing the data transmission rate of the network and increasing the data transmission delay. Although the network working time of the entire intelligent minefield is prolonged, However, the data transmission delay time is too long, which is very dangerous in actual work
