Techniques for Enhancing Security in Wireless Sensor Networks

摘要

Security of transmitted data is a most important issue in any communication network. Whileconcerning with security of data; attributes such as energy efficiency, low power consumption and lesscomputation time must be taken care of. WSN strives to use those techniques for data security and dataaggregation that works on low communication and computation cost because sensor nodes are resource limited.This study deals with performance comparison of different security schemes which claims to work on lowcomputation and communication cost along with the discussion on different security techniques based on dataaggregation concept. It has been observed from the analysis that security schemes based on data aggregationconcepts are more suitable for WSN than others.
