Intrution Resilience Using Self-Healing Mechanism In Mobile Unattended Wsns

Roshil K Das, J.Arun

Wireless Sensor Networks (WSNs), by their distributed nature, limited sensor resources, and lack of tamper resistance the networks are affected to a large area of attacks. The security measures become ineffective, if a sensor is corrupted and thereby the adversary learns all secrets. Trusted third party or access to a source of high-quality cryptographic randomness is required to recover secrecy, once a sensor is compromised with an adversary. But in the case of an Unattended Wireless Sensor Networks (UWSNs) the operation is not similar to Wireless Networks; here the sink visits the network periodically. The sensors in this network move according to some mobility models, that is why it is named as intrusion resilience in Mobile Unattended Wireless Sensor Networks. The advantage of this network is, it is independent from security (e.g., sensors move to improve area coverage). By leveraging sensor mobility it also introduces a cooperative protocol and it allows compromised sensors to recover secure state after compromise
