A comprehensive survey on energy efficient routing techniques and various attacks in wireless sensor networks

Demand and application of Wireless Sensor Networks (WSN) has grown rapidly during last decade. Wireless sensor networks follow distributed nature of sensor deployment, these networks are vulnerable to various threats which can affect the communication performance and functioning of WSN. These threats are widely known as security attacks on sensor nodes. Along with security threats, Quality of Service and energy efficiency is also considered as challenging task for researchers in WSN. For real-time applications, packet delivery and energy consumption are important tasks which can improve the performance of Wireless Sensor Network communication. Recent works are focused on the security and energy efficient communication in Wireless Sensor Networks. In this paper, we present recent studies in the field of WSN which includes security, sensor node localization and energy aware communication for better quality of communication. Drawbacks of WSN are security attacks, battery capacity is very less and there are practical problems in the deployment of the nodes. A comparative study is also presented by considering various threats on WSN architectural layers. Similarly, energy aware approaches are also compared based on the localization Error performance, Energy aware routing techniques and secure routing protocols for data encryption and decryption. This study shows the current problems of WSN communication in terms attacks on different layers and actions taken. The challenging factor in WSN is conserving the Energy for improving the network lifetime, improving performance and WSN localization. © 2020, Research Trend. All rights reserved.
