Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] Such as figure 1 , figure 2 As shown, a routing control method based on large-scale WSN emergency monitoring is carried out according to the following steps:

[0049] Step 1: Build a network model;

[0050] Randomly distribute N sensor nodes and a gateway node in the preset monitoring area, each sensor node has a unique identification number, and each sensor node has the same initial energy, data processing and communication capabilities;

[0051] In this example, we randomly distribute 200 sensor nodes in a 500×500m 2 In the monitoring area of ​​, the gateway node is located in the center of the monitoring area, and the identification number of each sensor node is set from 1 to 200 in turn.

[0052] Step 2: Network initialization;

[0053] Each sensor node and gateway node establishes a "neighbor node record table" by br...

Abstract

The invention discloses a routing control method based on big-scale WSN (wireless sensor network) emergency monitoring, which comprises four steps of building a network model, initializing a network, electing a cluster and transmitting data, wherein in the data transmission process, a cluster node selects a trunking mode of one hop or multiple hops to send effective monitoring data back to a gateway node according to the fact whether the gateway node is in a self 'neighbor node log sheet'; and in the trunking mode of multiple hops, the current node selects different algorithms to find a next-hop route node according to the self residual energy situation. The routing control method has the outstanding effects that the cluster node and the gateway node are communicated in the trunking mode of one hop or multiple hops to avoid excessive energy loss caused by long-distance transmission. According to the mechanisms of a cluster node and relay node election method, self-adaption power regulation, message delay forwarding control and the like, network energy consumption is saved and balanced so as to delay the time of the first dead node and improve the network performance.

Description

technical field [0001] The invention belongs to the routing technology in the wireless sensor network, in particular, it is a routing control method based on large-scale WSN emergency monitoring. Background technique [0002] Wireless sensor network (Wireless Sensor Network, WSN) is composed of a large number of micro sensor nodes deployed in a specific monitoring area, and is a network system established through wireless communication. Due to its low cost, easy implementation, large scale, and self-organization, WSN is widely used in environmental monitoring and protection, medical care, and military applications. However, the limitation of energy and function of sensor nodes restricts the effective development of WSN applications. [0003] Routing protocols largely affect important performances such as energy efficiency, delay, and robustness of the network. Efficient and applicable routing protocols can make up for the lack of energy and functions of a single sensor nod...
