Method for improving transmission efficiency of wireless ad hoc network

Abstract

The invention discloses a method for improving the transmission efficiency of a wireless ad hoc network, and the method comprises the steps that communication nodes report parameters related to transmission priorities to a central control node, and the central control node calculates the transmission priority of each communication node according to the obtained parameters and a preset algorithm; according to a preset transmission priority threshold, candidate nodes meeting the threshold are selected to form a candidate node set; one candidate node with the highest priority is selected as a required sending node, and the central control node schedules the required sending node to send data in a transmission time slot # n; whether other candidate nodes except the required sending node can beused as selectable sending nodes or not are judged according to a preset judgment rule and transmission priorities from high to low; and the central control node schedules the optional sending node to send data in the transmission time slot # n. According to the method, two or more concurrent transmissions in the network are coordinated through the scheduling method, the problem that concurrent transmission cannot be achieved due to common-channel interference is avoided, and the network transmission efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ad hoc networks, in particular to a method for improving the transmission efficiency of a wireless ad hoc network. Background technique [0002] Wireless ad hoc network is a new type of wireless network architecture completely different from traditional wireless cellular networks, including a temporary autonomous network of multiple communication nodes. The nodes in the network are all equal, and each communication node is equipped with a wireless transceiver, which has the functions of sending, forwarding and receiving, so any two nodes in the network can communicate through a direct link or a multi-hop link. Compared with traditional cellular networks, wireless ad hoc networks do not need to rely on infrastructure, and have the advantages of flexible and simple networking, high network reliability, and large coverage. They are widely used in public security, military battlefields, post-disaster reconstr...
