Wireless sensor networks are widely utilized in military areas, constructing smart cities and disaster management to monitor environmental conditions like temperature, pressure, etc. They transmit the aggregated data and deliver them to the base station via intermediate nodes with less cost. But, the major challenges in this networks are security and energy efficiency. In case of vulnerable attacks to the network, it may cause loss of data packets. Moreover, if the routes are not chosen properly then the lifetime and efficiency of the network may get affected. To address these issues, a Highly Secure and Optimal Route Selection (HSORS) protocol is proposed in this paper. The HSORS protocol comprises four stages: (i) cluster formation, (ii) encryption, (iii) malicious node detection, and (iv) optimal route selection. At the first stage, the cluster is formed and the data is aggregated from the respective cluster. In the second phase, the aggregated data is encrypted for data confidentiality. At the third stage, the malicious nodes are blocked on the basis of trust mechanism and at the final stage, the most optimal route is selected by the Shark Smell Optimization algorithm. The proposed HSORS protocol is tested in the MATLAB platform then the results are compared with the existing schemes. Based on the experiments carried out, it is confirmed that the proposed HSORS protocol has superior results as compared to the existing schemes in terms of security, energy consumption (0.45 J), Packet Delivery Ratio (65%), detection ratio (85%), throughput (98%), and packet drop ratio (5%).
