[0028] 1. Bandwidth calculation method of wireless ad hoc network based on time slot division

[0029] First, explain the bandwidth calculation method when hidden terminal conflicts are not considered. Bandwidth calculation can be realized by exchanging routing tables containing bandwidth information and routing information between neighboring nodes. Let CFS(x,y) denote the public free time slot set of the link (x,y), and CFS_bw denote the reservation message from the downstream node The set of public free...

Abstract

The invention discloses a method for calculating the bandwidth and distributing the bandwidth in a wireless ad hoc network. The method includes the TDMA-based bandwidth calculation method in the wireless ad hoc network and the bandwidth distribution scheme based on the service priority, wherein the TDMA-based bandwidth calculation method in the wireless ad hoc network includes the bandwidth calculation method under the condition of not considering a hidden terminal and the bandwidth calculation method under the condition of considering the hidden terminal. The available bandwidth information between any two nodes is obtained, and a source node can select the routing, meeting the bandwidth requirement, to the target node and can be used for deciding whether to allow new connection to be accepted or not. According to the self-adaption bandwidth distribution mechanism based on the service priority, the emergency degrees of service requirements of different services are taken into consideration, application is flexible, implementation is easy, and the method is feasible.

Description

Technical field [0001] The present invention relates to a method for calculating network bandwidth, alleviating congestion, and reasonably allocating bandwidth in a wireless ad hoc network. It specifically includes a bandwidth calculation method and a bandwidth allocation plan, and particularly relates to a bandwidth calculation method based on time slot division and based on business priority. The design of advanced adaptive bandwidth allocation scheme belongs to the field of information network technology. Background technique [0002] The wireless ad hoc network, with its outstanding characteristics of centerlessness, mobility, and self-organization, has broad application prospects because it does not need to rely on infrastructure such as base stations and communication cables. Its networking technology has been a research hotspot in recent years, emergency communications, battlefields Information reconnaissance, tactical communication, etc. are typical application scenarios....
