Refining Bogus Data in Wireless Sensor Network Using Non Repudiation and Enrouting Filter Mechanism

Wireless sensor network is usually composed of a large number of sensor nodes which are interconnected through wireless links to perform distributed sensing tasks. When a sensor node generates report after being triggered by a special event, it will send the report to a data collection unit (also known as sink) through an established routing path. Wireless sensor networks are usually deployed at unattended or hostile environments. Therefore, they are very vulnerable to various security attacks and also suffer from injecting bogus or false data attack and send the bogus data to the sink to cause upper-level error decision, as well as energy wasted in en-route nodes.
