Improving UWSNs security and data reliability using a cluster controlled mobility scheme

This paper proposes a new Self-Healing scheme based on Cluster Controlled Mobility (SH-CCM) for UWSNs. The proposed SH-CCM scheme uses the idea of mobility within a cluster of sick sensors beside the idea of the hybrid cooperation between both reactive and proactive peers and these sick sensors. This increases the chance of finding health neighbours and as a result it enhances both data security and reliability. The proposed SH-CCM scheme will help the sick sensor to self-heal and restore its backward secrecy faster and better than the schemes without mobility. A set of simulation results are carried out to demonstrate the effectiveness of the proposed SH-CCM scheme in the presence of a powerful, realistic adversary (ADV). The performance is measured in terms of compromising probability, probability of Bse (Backward Secrecy) to be compromised, and the data reliability. The obtained results ensure that the proposed scheme has a better performance over the conventional schemes without controlled mobility.
