Problems solved by technology

[0004] Aiming at the problem that the entire wireless sensor network fails due to too fast energy consumption of nodes near the Sink, the present invention proposes an energy-saving and safe routing method and system for wireless sensor networks based on mobile nodes. Based on the present invention, energy consumption of network nodes can be saved, etc Under the constraints of multiple conditions, the reliability and security of network data are guaranteed, and the effective working time of the network is extended while ensuring the normal operation of the network

Embodiment 1

[0124] The wireless sensor nodes are randomly distributed in a 100X100 rectangular area, the number of nodes is 100, the communication radius of the mobile node is r=25cm, the mobile node moves along a straight line, from the position (0, 50) to the position (100, 50), exactly horizontal across the entire area. After the mobile node completes a movement, it immediately returns to the starting point to start a new round of movement. Normal nodes generate one packet per second. Simulate from the following aspects:

[0125] 1. Network lifetime comparison

[0126] The original intention of designing energy-saving and secure routing for wireless sensor networks based on mobile nodes is to avoid the problem of excessive energy consumption caused by multi-hop network nodes, especially to overcome the network unavailability caused by the fact that the energy of nodes closer to the Sink is exhausted first. Phenomenon. The mobile node keeps moving, and important nodes and mobile nod...

Abstract

The invention discloses a mobile node-based wireless sensor network energy-saving secure routing method and a system thereof. The method includes: an important node in the wireless sensor network is determined, and communication rule between the important node and the mobile node is established; according to the communication rule, speed control is carried out on the mobile node; and network security control is carried out on the wireless sensor network. The invention considers the factors of energy consumption of node, node data transmission reliability and network security and ensures operational use time and security of the whole sensor network under the restriction of multiple conditions.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an energy-saving and safe routing method and system for a mobile node-based wireless sensor network. Background technique [0002] Wireless sensor network is an emerging technology, which completely adopts distributed processing, and has many advantages such as high monitoring accuracy, good fault tolerance, large coverage area, and remote monitoring. At present, wireless sensor networks have broad application prospects in military, industrial, civil and many other aspects, and are one of the current research hotspots. The prominent feature of wireless sensor network is that static nodes are scattered randomly in a fixed area, and node data is transmitted through multi-hop. The prominent problem brought about is that the energy consumption of peripheral nodes closer to the sink node (Sink) in the network is faster, because these core nodes bear more communication ...
