Implementation method of hybrid routing protocol based on time pulse source

Abstract

The invention provides an implementation method of a hybrid routing protocol based on a time pulse source, belongs to the technical field of communication, and mainly solves the problem of how to balance network routing overhead and delay overhead and provide a high-capacity, low-delay and high-dynamic ad hoc network routing protocol for a system. According to the scheme, a routing protocol actively and periodically broadcasts pulse messages through pulse nodes to complete establishment and maintenance of a path tree, and when non-pulse nodes have data requirements, path establishment, maintenance and path optimization are completed along the path tree according to needs. The method has the advantages that the problems that the overhead is large and the method is not suitable for large-scale nodes due to the fact that the active routing protocol and the passive routing protocol adopt a flooding mode to carry out path discovery and path maintenance are better solved, the problem that the end-to-end delay of the passive routing protocol is large is solved, and the scheme is more suitable for the conditions that the network extension structure is rapidly changed and the network node scale is large.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for realizing a hybrid routing protocol based on a time pulse source. Background technique [0002] The wireless self-organizing network, MANET (Mobile Ad Hoc Network), is a technology different from the traditional wireless communication network. The traditional wireless cellular communication network requires the support of fixed network equipment such as base stations for data forwarding and user service control. The wireless self-organizing network does not need fixed equipment support, and each node, that is, a user terminal, forms a network by itself. During communication, data is forwarded by other user nodes. This network form breaks through the geographical limitations of traditional wireless cellular networks, and can be deployed more quickly, conveniently, and efficiently. It is suitable for communication needs in some emergency situations, ...

Problems solved by technology

However, with the popularization and research of on-demand routing protocols such as ad hoc network on-demand distance vector (AODV) routing protocol and dynamic source routing (DSR) protocol, the exposed problem has become more and more obvious, that is, the on-demand mechanism will be largely Increase the end-to-end transmission delay of data packets and cause large delay fluctuations
