Embodiment Construction

[0045] The technical solutions and effects of the present invention will be described in detail below in conjunction with the accompanying drawings. A simulation result compared with the existing DCPF protocol is also provided as an example, but this example is only used as an example for the purpose of explaining the present invention, and should not be construed as a limitation of the present invention.

[0046] The present invention relates to a media access control protocol in a wireless sensor network, in particular to an interference-free pipelined data collection method (Interference-Free Duty-Cycling and Pipelined-Forwarding, IF-DCPF) based on duty cycle scheduling. The present invention designs a notification message It can better solve the interference problem between nodes at the same level. It realizes an invention that can still achieve a good data collection effect when there are many nodes at the same level and the network traffic is heavy.

Abstract

The invention discloses an interference-free pipelined data collection method based on duty ratio scheduling, which comprises the following steps that: S1, a sink node communicates with nodes within aone-hop range of the sink node and acquires related information; S2, the sink node generates a represented data packet and unicast the packet to each node in a one-hop range of the sink node one by one; S3, the level of each node in the one-hop range of the sink node to be 1 is set according to the received unicast packet, a sleep-wake-up scheduling time table is established to join the network,and then the scheduling time table is updated and broadcasted; S4, 1 is added to the value of the level domain of which the level is set to be the packet according to the received broadcast packet, asleep-wake-up scheduling time table is established to join the network, and then the sleep-wake-up scheduling time table is updated and broadcasted; and S5, after the node joins the network, the sensing data is forwarded to the sink node hop by hop.

Description

technical field [0001] The invention relates to a media access control protocol in a wireless sensor network, in particular to a non-interference pipeline data collection method based on duty ratio scheduling. Background technique [0002] With the continuous development of Internet of Things technology, Wireless Sensor Network (WSN), as an important Internet of Things technology, is becoming more and more critical. play an important role. [0003] WSN can be applied in many event monitoring fields, such as the monitoring of infrastructure environments. When monitoring areas with linear topology (such as oil / gas pipelines and railways), due to the linear characteristics of the monitored area, sensor nodes are naturally deployed in a manner with thin or thick linear coverage, thus forming a linear sensor network ( LinearSensor Network, LSN). Data collection is one of the most important services that LSN can provide, in which the sink node collects the data sensed by sensor...
