Abstract:
In Wireless Sensor Network (WSN) is a standalone network capable of autonomous operation where nodes communicate with each other without the need of any existing infrastructure. They are self configuring, autonomous, quickly deployable and operate without infrastructure. Mobile ad hoc networks consist of nodes that cooperate to provide connectivity and are free to move and organize randomly. These nodes are often vulnerable to failure thus making wireless network open to threats and attacks. Communication in WSN relies on mutual trust between the participating nodes but the features of Wireless Sensor Network (WSN) make this hard. Nodes sometimes fail to transmit and start dropping packets during the transmission. Such nodes are responsible for untrustworthy routing. A trust based scheme can be used to track these untrustworthy nodes and isolate them from routing, thus provide trustworthiness. The proposed system is very simple to implement and manipulates future behaviour via dynamic computation of previous data forwards and has records of historical behaviours. Unlike other systems’ default trust assumptions, our system initialises trust with forwarding ratios. We proposed a trust based malicious detection algorithm to efficiently measure the performance of networks and handle those attacks accurately and separately. Local monitoring algorithm was used to detect the multiple attacks. After detecting these attacks and attacker nodes are eliminated. The simulation results s
