specific Embodiment approach

[0033] The specific implementation is as follows, a wireless ad hoc network energy-saving transmission method, including a wireless ad hoc network with a central control node, in order to illustrate the solution of the present invention simply and clearly, as follows figure 2 A wireless ad hoc network case shown in the example, the network includes seven nodes A ~ G, assuming that node A is the central control node, nodes B ~ G are communication nodes, the routing table between the nodes is as follows figure 2 shown.

[0034] according to figure 1 In the schematic diagram of the DRX process of the LTE system shown, nodes A to G send discovery signals in assigned time slots, and while one node sends a discovery signal, other nodes receive and detect the discovery signal. For example, node C sends a discovery signal, and nodes A, B, and D~G receive and detect the discovery signal. If the receiving node detects the discovery signal, that is, the power of the detected discovery...

Abstract

The invention discloses a wireless ad hoc network energy-saving transmission method, which comprises a wireless ad hoc network with a central control node, and comprises the following steps that: 1) the central control node of the wireless ad hoc network acquires neighbor node routing tables of all communication nodes, and acquires routing information of the whole wireless ad hoc network through analysis and calculation; 2) when the residual electric quantity of the communication node is lower than a preset electric quantity threshold or the average throughput of the communication node is lower than a preset throughput threshold in a preset time window, a dormancy application is sent to the central control node; and 3) after receiving the dormancy application of the communication node, the central control node judges whether the communication node is a communication necessary node or a replaceable node exists, and if the communication node is an unnecessary node, the dormancy application of the communication node is allowed. According to the invention, under the condition that the network transmission function is not influenced, the nodes with low transmission quantity and low electric quantity are dormant, so that the energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless ad hoc network energy-saving transmission method. 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 reconstruction, and first aid m...
