Wireless Sensor Networks Security Issues, Attacks and Challenges: A Survey

Abstract

In recent years, Wireless Sensor Networks (WSN) are developing a real workforce in true condition. WSNs are broadly utilized in the following checking and controlling applications. Inspite of their predominant role in wireless applications, it may also introduce some research complexities. This paper focuses on the survey of various security issues faced by wireless sensor networks such as data security at node and network level and recommends solutions to secure WSN. Despite the difficulties in wireless sensor network, this survey centers around the attacks of different varieties in WSNs such as physical, communication, Base station, and routing protocol attacks and provides some solutions for the attacks. This paper address the issues on versatility, correspondence steering conventions, and security. This study center around security prerequisites, WSN applications, distinctive attacks and safeguards, and various ongoing issues and difficulties. This paper gives a brief overview on challenges of WSN like routing and application based challenges, key management, and new technology based challenges. Moreover, Software Defined Networking (SDN) mechanism is used to support the bendable routing and communication between sensor nodes. This survey discusses the challenges and security issues of SDN in WSN.
