Sensor-Network-Security-A-Survey

Description: Wireless sensor networks(WSNs) use small nodes with constrained capabilities to sense,collect,and disseminate information in many types of applications.As sensor networks
become wide-spread,security issues become a central concern,
especially in mission-criticaltasks.In this paper,we identify
the
threats and vulnerabilities to WSNs and summarize the defense
methods based on the networking protocol layer analys is ?rst.Then we give a holistic overview of security issues.These issues are divided into seven categories:cryptography,keymanage-
ment,attack detections and preventions,securer outing,secure
location security,secure data fusion,and other security
issues.
Along the way we analyze thead vantages and disadvantages of
current secure schemes in each category.Inaddition,we also summarize the techniques and methods used in these categories,and point out the open research issues and directions in each
area.
