In this paper, we propose an innovative adaptive secure image delivery approach, to achieve effective and efficient image encryption based oil ail optimal transmission rate in terms of energy efficiency in wireless sensor networks (WSN). Our contribution is three folds-First, the proposed component based selective encryption scheme achieves high image Security, while incurring little encryption overhead; furthermore, the proposed adaptive encryption scheme achieve the best security effort Within delay bound finally, the proposed transmission rate optimization improves energy efficiency, and feeds back effective path capacity parameters for adaptive encryption. Simulation results show a significant gain in both energy efficiency and security based oil the proposed approach for image secure transmissions in WSN.
