The Relative performance of Security protocols and attacks in Wire¬less Sensor Network

Abstract

Wireless Sensor Network isorganized by arrangingahuge number of sensor nodes in a region to the investigation of normally remote locations. A Wireless sensor network contains various applications such as landslide detec­tion, automotive application, health, noise level, environmental, vehicular movement, and battlefield. A Sensor node has different components to complete the work for sensing the data, transmitting, and processing the data into the network. Security is a very challenging issue in the WSNs. Various security threats and attacksmay affect or damage the functioning (activity)of these networks..In this review paper, we explain the architecture of WSNs then applications. We explain the term attack threat, vulnerabilities, and security requirements.Further, we describe the attacks. Attack divided the main two types active and passive. This paper focuses onseveralsecurity attacks likeBlackhole, fabrication, Sybil, DoS, sinkhole, wormhole, flood­ing. We have also explained security protocols are 3 categories.  Data-Centric, Geographic, and hierarchical pro­tocol. Other are SPIN, LiSP, LEDs, LLSP, LEACH protocols. Finally, we represent the comparative tables for WSNs attacks with counter­measures, layers and secure protocols. We can provide tabular representation security Protocols with various key functionality.
