WIRELESS SENSOR NETWORKS SECURITY (IJSAR Book 1)

Wireless Sensor Networks (WSN) is a significant technology which is attracting many researchers. Advancement in Wireless communication and electronics has promoted to develop cost-efficient, multi-functional, small-size, cheap and smart sensors. Deployment of such network is providing extensive benefits especially in scarce areas. With an advancement is manufacturing and deployment of such network, one major thing is to be taken care of and that is "security within WSN". There is a huge scope for research in this area, many approaches are already proposed for this specific area. In this paper we have firstly explored the obstacles in WSN security, then the security needs in WSN, after that we have identified the type of attacks and threats associated within WSN also we have reviewed proposed security mechanisms and we have discussed layer wise threats and attacks and techniques to address them and at last parameters which is to be considered while addressing the attacks and threats of WSN.
