A Secure Routing Method for Wireless Sensor Networks Based on Multi-attribute Decision Making

Abstract

The invention discloses a wireless sensor network secure routing algorithm based on multiple attribute decision making. Based on degree distribution characteristics of a scale-free topology, the performance requirements of the network are considered comprehensively, the energy transmission efficiency, the load and the packet loss rate are added to a multiple attribute decision making model, various attribute factors are balanced by the concept of a relative entropy, a node determines the minimum hop number to a base station, a forward neighbor list is built, and according to the decision making model, the optimal routing node is selected from the forward neighbor list. Thus, selective forwarding attacks can be effectively avoided, the network energy is balanced, and the life cycle of the network is prolonged.

Description

technical field [0001] The invention relates to the field of wireless sensor network routing security, in particular to a wireless sensor network security routing algorithm based on multi-attribute decision-making. Background technique [0002] Routing protocols are responsible for selecting the optimal path for data transmission and forwarding data packets from source nodes to destination nodes. Routing security is an important part of wireless sensor network (wireless sensor networks, WSNs) system security. WSNs are facing security risks such as false routing information attacks, selective forwarding attacks, sinkhole attacks, sybil attacks, and wormhole attacks. Analyze the characteristics of these attacks and their impact on WSNs network layer performance Mainly include: packet loss, delay, energy exhaustion, etc. Among them, selective forwarding is a relatively common type of network layer attack. The attacker effectively destroys the normal collection of network data...

AI Technical Summary

Problems solved by technology

[0003] The scale-free topology is widely used due to its strong fault tolerance, but there are nodes with a large degree of partiality in the scale-free network, and the entire network will be paralyzed when these nodes are attacked

This feature of the scale-free network will directly affect the security of network data transmission, especially when the network is under deliberate attack, the entire network will be paralyzed

[0004] Most of the existing literature avoids the malicious node of selective forwarding by detecting the packet loss of the node. While resisting the selective forwarding attack, it cannot take into account the delay, energy and other performance of the network, so that the data packet cannot reach the destination node. Some nodes run out of energy and split

However, in the routing research on scale-free networks, most of the research focuses on how to balance energy consumption and reduce congestion in the network. For the secure routing of scale-free networks, scholars have not aroused in-depth research.
