Problems solved by technology

However, for large-scale WSNs, the synchronization of nodes is a difficult problem in itself, and it is also complicated to predetermine a strict schedule
The reliability of the wireless sensor network depends on the reliability of the nodes. The unbalanced load leads to the rapid depletion of the energy of some nodes, leading to the premature death of some nodes, which greatly reduces the reliability of the sensor network.
Especially in the broadcast mode, the asynchronous low duty cycle brings about asynchronous wake-up of nodes, which causes highly redundant transmission of broadcasts and consumes excess energy, and the link algorithm of the ADB broadcast protocol intensifies this phenomenon

Embodiment Construction

[0033] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0034] A method for realizing the HR-MM broadcast protocol for an asynchronous sensor network, comprising the following steps:

[0035] Step 1. First, by maintaining the broadcast state of neighboring nodes, balancing the broadcast-forwarding ratio and end-to-end delay, effectively reducing the broadcasting-forwarding ratio without increasing the delay;

[0036] Step 2, secondly, use the multi-standard balance mechanism of link quality and node residual energy to prolong the average life of nodes, thereby prolonging the life of the network;

[0037] Step three, finally, further reduce the number of broadcast forwarding through the delayed forwarding mechanism, reduce redundant forwarding, reduce the probability of broadcast collision, and reduce the average power consumption of nodes.

[0038] Step 1 is realized by a balance algorithm of network de...

Abstract

The invention discloses an implementation method for asynchronous sensor oriented hopcount reduced broadcasting with multiple metrics (HR-MM) broadcasting protocol. The method comprises the following steps: firstly, through the maintenance of the broadcasting state of neighboring nodes, balancing the broadcasting forwarding ratio and the end-to-end delay and effectively reducing the broadcasting forwarding ratio without the increase in the delay; secondly, using the multi-standard equilibrium mechanism of link quality and residual energy of nodes to extend the average service life of the nodes; and finally, through a delay forwarding mechanism, further reducing the number of broadcasting transmissions and reducing redundant forwarding. The wireless sensor network data broadcasting method of the present invention is applicable not only to a large-scale network scene but also to a low duty ratio operating environment.

Description

technical field [0001] The invention relates to an implementation method of a wireless sensor network broadcast protocol HR-MM (Hopcount Reduced Broadcasting with Multiple Metrics) that supports broadcasting, belongs to the MAC layer protocol design in the wireless sensor network, and is used to solve the asynchronous duty ratio in the wireless sensor network Broadcast issue in operational mode. Background technique [0002] Wireless sensor network (WSN) is a multi-hop self-organizing network formed by a large number of nodes deployed in the monitoring area through wireless transmission, which is used to collect, process and transmit sensing information cooperatively. The MAC protocol allocates limited wireless communication resources between sensor nodes and determines the use of channels. It is the hub connecting physical layer hardware and upper layer software protocols, and is one of the most important technologies in wireless sensor networks. [0003] An important comm...
