A Clustering Based Approach to Provide Security to Wireless Sensor Network

In past few years the wireless sensor network has been able to attract a lot of research related to ubiquitous computing and networking such as communication, network formation, enhancing battery life, security, etc. Amongst these, this paper's focus is on one of the key concern to any data centric network i.e. security. Security plays a vital role when it comes to wireless sensor network. A malicious node can affect the network in various forms eventually disrupting the working of entire network. The paper proposes a cluster based approach to prevent a malicious node from entering a wireless sensor network. The simulation of the proposed security system helped in understanding how clustering can be useful in securing the sensor network from malicious node as early as deployment of cluster heads.
