Abstract—Secure data transmission is the major issue in Wireless Multimedia Sensor Networks (WMSNs). One of the most well-known strategies that are essential in solving the privacy and security issues is access control and authentication. These techniques can stop malicious nodes from joining the network. However, because to the complexity of their encryption, they place an unsustainable computational burden on the energy-constrained sensor nodes. To ensure an efficient data access, this paper proposes a simple and effective authentication and access control mechanism called as Hierarchical Authentication Assisted Clustered Routing (HA2CR). Initially, HA2CR clusters the entire network into different clusters and then applies authentication at two stages; one is between Base Station and Cluster Head and another is between Cluster head and Cluster Member. The Second level authentication is a mutual authentication and allows both clustered and cluster member to check the authenticity of each of them. Simulation experiments with different scenarios show the performance effectiveness of HA2CR in the adversary identification and qualitative data delivery at base station. The average Malicious Detection Rate (MDR) and Packet Loss Rate (PLR) of proposed access control mechanisms observed as 92.4200%, and 6.1666 respectively. From the results the effectiveness of proposed method had proven in terms of larger MDR and lower PLR.
