Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0039] The network topology proposed by the present invention is strip-shaped, which is a semi-enclosed geographical space whose cross section is rectangular or approximately rectangular, and the depth distance L is much larger than the width D and height H (D≥H) of the cross section. A tuple represents a narrow long space as , such as figure 1 shown.

[0040] Since the ribbon wireless sensor network, such as figure 2 The topological diagram of the strip sensor network is limited by geographical conditions. The nodes cooperate to complete the monitoring and monitoring tasks of each area, and send the information to the Sink node through multi-hop. Due to the limitation of geographical features and the influence of outdoor temperature and humidity, the quality of wireless communication in narrow an...

Abstract

The invention discloses a banded wireless sensor network data routing method for distribution network monitoring. Aiming at the characteristics of dense nodes, large scale, large quantity and high real-time requirement of monitoring of a distribution network, a multi-priority fast directional routing algorithm based on multi priority based on gradient. According to the method, for different data, a multi-priority service strategy is employed and a power function mechanism is introduced at the same time to select an optimal next hop routing node, and both the priority of a message and the load balance of a network are considered. The delay of transmitting real-time data is effectively reduced, and good energy effectiveness is provided for the network. The method is more suitable for a massively deployed wireless sensor network (WSN) with banded topology and intensive real-time data collection.

Description

technical field [0001] The invention relates to the field of wireless sensor network data routing, and more specifically, relates to a band-shaped wireless sensor network data routing method for distribution network monitoring. Background technique [0002] According to the application requirements of intelligent monitoring of distribution network and the characteristics of corridor belt environment, it is of great significance to construct a real-time reliable, autonomous and efficient belt heterogeneous sensor network. The strip topology sensor network based on the distribution network has the characteristics of dense sensor nodes, large scale and large quantity, so designing a reasonable data routing method is of great significance for the construction of the sensor network. [0003] In the prior art, there are few researches on the routing method of the strip sensor network, which is mainly based on the chain topology. Ma Gonggong, Tang Feilong. Chain-based clustering r...
