Security Attacks and Prevention in Wireless Sensor Networks in NS2

Security of deployed wireless sensor networks (WSNs) has become a crucial task as the deployment of WSN'S grows. This paper proposes a novel way and develops a mechanism to prevent wormhole attacks by an algorithm to manage a large number of nodes using node ID. Also, the proposal creates a load balancing feature for monitoring a hierarchical system for nodes and extra packet header on each node to make sure it is not compromised. Even though an attack is inevitable on a live node network using a simulator, this paper has shown how the network nodes can be rerouted to avoid the attacked nodes.
