Reliability Evaluation of Wireless Sensor Networks Using EERN Algorithm

Wireless sensor network senses the environment where the human access is limited. Sensor nodes will collect the information and pass it to the sink node. When passing the information, malicious node or compromised node will corrupt it and forward it to the sink node. In the receiver side, a corrupted message will create a problem. The proper information will not be conveyed to the sink node. The presence of compromised node will generate incorrect report and it affects the event detection. In this paper, we proposed an EERN algorithm to provide reliability for the entire wireless sensor network against compromised node. To provide reliability and to save time, we introduced vigilant node and aggregator node. Aggregator node will detect the suspicious node. Vigilant node will identify the suspicious node as malicious, compromised or faulty node.
