Wireless Sensor Networks: An Overview on its Security Threats

摘要: Wireless sensor networks have become a growing area of research and development due to the tremendous number applications that can greatly benefit from such systems has lead tiny, cheap, disposable self contained battery powered computers, known as nodes or “motes”, which accept input an attached sensor, process this data transmit results wirelessly transit network. Despite making possible, very wireless nature sensors presents security threats when deployed for certain like military ,surveillances etc . The problem is constrained resources on nodes, means architectures used traditional are not viable. Furthermore, additional vulnerability because often placed in hostile dangerous environment where they physically protected. In paper we discuss some challenges faced by WSNs.
