TDMA-CADH Cross-Layer Approach for IoT Performance Aspects

A network in which the items use a variety of different technologies is known as the Internet of Things (IoT). Wireless sensors networks are the most common objects in the IoT. It has numerous low-power sensors that detect environmental conditions, perform data processing. These sensors work together to perform complex tasks via wireless communication. In this context, we have proposed TDMA CADH (TDMA Cross-layer Approach Aware Delay in Heterogeneous WSN) approach based on routing information. The goal is to ensure the constraint of energy consumption and therefore, network lifetime. The main concept is to minimize delays and optimize distribution channel. In order to validate the improvements made by our approach, we carried out a simulation using a network simulator NS3 (Network Simulator NS3), in which the performances of our proposal are evaluated and compared with the already existing approaches, namely, Rand-LO (Random Leaves Ordering), Depth-LO (Depth Leaves Ordering) and Depth-ReLO (Depth Remaining Leaves Ordering).
