A Review on the Network Security Related to Wireless Sensor Network

Network security is vital for securing all information that passed through network computer; hence network security is the most important element in information security. Security is one of the critical concern occurred in WSN due to limitations in computing and fixed resource. Wireless sensor network have a broad area of invaluable games, defence, civil, household, entertainment application. WSN nodes behave as information source by sensing and collecting sample of data from their environment. Energy efficiency, adaptive medium access control, scalability are the performance measures considered by WSN that posed interesting challenges to the community of engineers. The wireless sensor network is divided into four classes: threats to sensor network security, security requirements, attacks and security. The obstacles of sensor networks are fixed storage space and memory, drawback of power, unreliable and unattended operation. Security requirements are availability, self management, time synchronization, secure localization and authentication.
