Mobile Ad Hoc Networks (MANETs) and Wireless Sensor Network (WSN) technologies have been using for many aspects of our day living. The rapid increase in the number of these devices in communicating-actuating networks creates the Internet of Things (IoT) concept that appears in a number of unconventional applications. To achieve this connectivity, the IoT needs a communication model such as the TCP/IP communication model. In addition to the complexity of the IoT, where multiple heterogeneous devices, located in various contexts, could exchange information with each other, the design of interoperable, efficient, and scalable security mechanisms is much difficult. This paper, proposes a solution, which could be considered as a step forward for a centralized management of all security mechanisms into a single layer. The Security Layer aims to confirm the identity of the sender/receiver to help to block connections to potentially vulnerable services. Furthermore, this centralization would leave other IoT's communication reference model layers to perform their specified functions without paying attention to any security problems. The experimental results conducted using Network Simulator (NS2) simulator and the results were evaluated using different measures, packet dropped, packet delivery ratio (PDR), normalized routing load (NRL), throughput and end-to-end delay. These results showed that the proposed solution performed better than the normal communication model.
