Security and Privacy Issues in Wireless Sensor Networks

Abstract

Today, in modern world, technology has improved a lot with wireless communication. Wireless sensor network is normally constructed without any fixed network infrastructure. It is very simple, cheap, self-organized and easy to deploy the nodes in wide range. WSN protocols are mainly designed to focus on energy efficiency and lifetime improvement. Apart from those, WSNs face so many challenges due to limited number of resources available such as memory, computing, space, and bandwidth. The main duty of sensor node is used to collect the information from the environment and transmit the data to the control unit. Due to large number of collection and transmission, they should need to protect from hacker. WSNs need to provide security in all aspects of their architecture reference model. In this chapter, the main contribution includes architecture, attacks and countermeasures.
