Problems solved by technology

Moreover, the nodes in the route backup mechanism must constantly monitor the RREP messages sent by the adjacent nodes on the main route, so more control messages are needed for route monitoring, which increases the routing overhead
[0006] The field test of a new protocol usually requires a large number of vehicles and personnel, which is expensive and complicated. Therefore, it is an effective technical means to use relevant simulation tools to study the VANET routing protocol.

Embodiment Construction

[0034] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings, but the implementation and protection of the present invention are not limited thereto. Everything here can be realized or understood by those skilled in the art with reference to the prior art.

[0035] Such as figure 1 As shown, after the destination node receives the RREQ message, it generates an RREP message. Extend the RREP message format, and add four data fields on the basis of the original data field, which are used to store the abscissa, ordinate, horizontal component velocity of the moving direction, and vertical component velocity of the moving direction respectively for the node currently forwarding the RREP message. The destination node will first fill in the data fields of the RREP message of the AODV protocol, and then call the GPS module to obtain it...

Abstract

The invention discloses an enhanced stable routing protocol for the vehicle Ad Hoc network. A source node finds a target node and obtains multiple effective routes to the target node; and in the route selection phase, a mechanism of the longest route effective time is introduced to select a route longest in effective time and more stable in performance for data transmission. In the route maintenance phase, if the main route is in failure, the source node directly uses the multipath standby route to repair the route, and the route repairing efficiency is improved. The enhanced stable routing protocol can improve the delivery rate of data packets, reduce the average end-to-end time delay, reduce the routing cost, and improve the performance of the vehicle Ad Hoc network.

Description

technical field [0001] The invention belongs to the technical field of VANET, and in particular relates to an Enhanced Stability Routing Protocol (ESRP, Enhanced Stability Routing Protocol for VANET) for VANET. Background technique [0002] Vehicular AdHoc Networks (VANET, VehicularAdHocNetworks) is a new research and application field of ad hoc networks. The basic idea of ​​VANET is: Vehicles within a certain range can exchange information such as vehicle speed, location, and sensor-perceived data, and automatically establish a mobile AdHoc network. [0003] Generally speaking, VANET supports two types of communication modes: vehicle-to-vehicle (Vehicle-To-Vehicle, V2V) communication and vehicle-to-infrastructure (Vehicle-To-Infrastructure, V2I) communication, which can realize inter-vehicle, vehicle-to-roadside Multi-hop wireless communication between infrastructures, these communication methods provide the possibility for VANET to realize a variety of new services and ap...
