An Efficient Monitoring Scheme for Malicious Node Detection in Wireless Sensor Networks

Security plays an major role in the ability to deploy and access trustworthy information from a wireless sensor network. Local monitoring schemes have proved to be effective mechanisms for security in Wireless sensor networks. Designing an efficient scheme integrated with good monitoring capability and also secure against various kinds of attacks is the need of the hour. Better performance is achieved at the cost of security concerns as a result an adversary might be able to determine which nodes to attack, so as to control or compromise a part or whole of the sensor network. Hence, we need to insert some security constraints into the monitoring schemes. This work analyses the performance of self monitoring scheme based on algorithmic approach and a more reliable approach which is efficient in terms of various network performance parameters compared to self monitoring scheme and secure employing location monitoring is proposed.
