A Survey on Wireless Sensor Network Security

S. Mohan, S. Grace Diana. S. Ramya

The significant advances of hardware manufacturing technology have boosted the deployment of Wireless Sensor Networks (WSNs).The WSN are used in many applications in military, ecological, and health-related areas. These applications often include the monitoring of sensitive information such as enemy movement on the battlefield or the location of personnel in a building. Security is therefore important in WSNs. However, WSNs suffer from many constraints, including low computation capability, small memory, limited energy resources and the use of insecure wireless communication channels. These constraints make security in WSNs a challenge. In this article we present a survey of security issues in WSNs.
