Abstract

In a wireless sensor network, some nodes may act selfishly and noncooperatively, such as not forwarding packets, in response to their own limited resources. If most of the nodes in a network exhibit this selfish behavior, the entire network will be paralyzed, and it will not be able to provide normal service. This paper considers implementing the idea of evolutionary game theory into the nodes of wireless sensor networks to effectively improve the reliability and stability of the networks. We present a new model for the selfish node incentive mechanism with a forward game node for wireless sensor networks, and we discuss applications of the replicator dynamics mechanism to analyze evolutionary trends of trust relationships among nodes. We analyzed our approach theoretically and conducted simulations based on the idea of evolutionary game theory. The results of the simulation indicated that a wireless sensor network that uses the incentive mechanism can forward packets well while resisting any slight variations. Thus, the stability and reliability of wireless sensor networks are improved. We conducted numerical experiments, and the results verified our conclusions based on the theoretical analysis.

Summary

Introduction

A wireless sensor network (WSN) is a wireless network that is constructed via the self-organization of a large number of sensor nodes. Considering the network security problems that exist today, at present, there is a significant amount of research being done on the security of wireless sensor networks from different perspectives with the aim of ensuring that the networks are operating effectively. In terms of security issues, the problems encountered by wireless sensor networks and traditional wireless networks differ greatly and are determined by the characteristics of the individual networks. Since the resources of sensor nodes are limited, processing power, storage space, energy, and other factors prevent direct application of mature and effective security protocols and algorithms to wireless sensor networks. Security issues faced by the wireless sensor network included physical security of nodes, security issues in the link layer, and security issues in the network layer [1,2,3,4,5,6,7]
