“…In any computer-related environment, security is considered as a nonfunctional requirement, which is not only used to maintain the availability and reliability of the whole system but also related to the protection of information and system. However, in wireless sensor networks, security issues are particularly important because on the one hand, the hardware functions of network nodes are seriously limited, and it is necessary to provide sufficient protection to protect them from malicious attacks; on the other hand, the deployment environment of wireless sensor networks makes it easy for the enemy to obtain sensor nodes illegally and destroy them [1][2][3][4]. Any destruction and interference to nodes will have a certain impact on the information obtained in the real world.…”

The scale of wireless sensor networks changes depending on specific application tasks. How to design a relatively simple security mechanism that can extend with the expansion of network scale is an arduous task. As the wireless sensor network mostly adopts the decentralized organization form, once the network nodes are distributed adequately, it is difficult to find out the failure of any node. In addition, the node has weak resistance to physical damage, so any node in the network may potentially become a cause of security vulnerability. In this study, firstly, the security standards that wireless sensor networks should have and the current security challenges faced by the network are discussed in detail, and the importance of security issues in wireless sensor networks is pointed out. Secondly, this paper studies and analyzes the current situation of wireless sensor network security problems including the internal and external attacks and the active and passive attacks. Thirdly, this paper also discusses the significance, concept, and characteristics of reputation and trust, the division and composition of reputation and trust system, and the common applications of the reputation and trust mechanism in wireless sensor networks.

“…Schemes like [15][16][17][18][19], exploit the Watchdog mechanism for local reputation builds up. Watchdog mechanism is based on passive acknowledgments which suffers from ambiguous collision and receiver collision problems [20], some authors devised their schemes that use monitoring based on explicit acknowledgments [21,22] at the cost of augmented communication overhead and some authors, such as [23][24][25], use other techniques for direct observation collection. For better detection accuracy, these schemes collaboratively detect selfish nodes thereby enabling nodes to disseminate their direct experience in the form of first-hand reputation ratings in the network.…”

Routing in mobile ad hoc networks is performed in a distributed fashion where each node acts as host and router, such that it forwards incoming packets for others without relying on a dedicated router. Nodes are mostly resource constraint and the users are usually inclined to conserve their resources and exhibit selfish behaviour by not contributing in the routing process. The trust and reputation models have been proposed to motivate selfish nodes for cooperation in the packet forwarding process. Nodes having bad trust or reputation are detected and secluded from the network, eventually. However, due to the lack of proper identity management and use of non-persistent identities in ad hoc networks, malicious nodes can pose various threats to these methods. For example, a malicious node can discard the bad reputed identity and enter into the system with another identity afresh, called whitewashing. Similarly, a malicious node may create more than one identity, called Sybil attack, for self-promotion, defame other nodes, and broadcast fake recommendations in the network. These identity-based attacks disrupt the overall detection of the reputation systems. In this paper, we propose a reputation-based scheme that detects selfish nodes and deters identity attacks. We address the issue in such a way that, for normal selfish nodes, it will become no longer advantageous to carry out a whitewash. Sybil attackers are also discouraged (i.e., on a single battery, they may create fewer identities). We design and analyse our rationale via game theory and evaluate our proposed reputation system using NS-2 simulator. The results obtained from the simulation demonstrate that our proposed
