INVESTIGATING SECURITY MECHANISMS IN WIRELESSSENSOR NETWORK
Keywords:
Wireless Sensor Network, Security, Network attacks, Key-Pre Distribution, SPREADAbstract
Wireless sensor nodes are gaining huge popularity in many domains. This data acquisition system has tremendous significance in defense, traffic management and many more areas. Ensuring the security of both the collected data and the process of data collection is vital for the success of WSNs (Wireless Sensor Networks).Security is achieved when one is able to address all possible kinds of threat to the device and the technology standards including the software approach and cryptographic approach. Cryptographic means alone are not sufficient to mitigate attacks ,the use of statistics, data analysis and techniques from economics like game theory, ant colony optimization techniques could help .The communication of a wireless sensor network can be eavesdropped quite easily due to its properties, thereby requiring security mechanism here as well. Then stochastic routing is also designed to reduce the probability of successful prediction by a malicious node which is also a serious kind of security flaw. SPREAD used in MANETs, could be considered in case of WSNs too. We aim to discuss and survey some existing security measures like SPREAD, random key pre distribution mechanisms, Actuation environments and stochastic routing protocols for security. We conclude in a note suggesting, a mix of societal norms, new laws, and technological responses as being necessary to address security in WSN full fledge swing.
