  Abstract

The Internet of Things (IoT) encompasses a wide various of heterogeneous devices that leverage their capabilities in environmental sensing, data processing, and wireless communication. Among these, wireless sensors are one of the most widely used technologies in such networks. However, Wireless Sensor Networks (WSNs) face significant challenges in Medium Access Control (MAC), particularly in power management and network lifetime. To address these issues and enhance network efficiency and reliability, we propose a MAC approach for WSNs based on routing data. This approach, termed TDMA-CADH (TDMA Cross-Layer Approach Aware Delay/Throughput in Heterogeneous WSN), employs a cross-layer strategy to optimize resource utilization by minimizing transmission delay, maximizing channel throughput, and ensuring energy efficiency and extended network lifetime. The primary goal of this work is to design an effective MAC approach for WSNs that adhere to energy consumption and network lifetime constraints while reducing delay and improving channel throughput. To evaluate the performance of TDMA-CADH, we conducted simulations using the Network Simulator (NS-3) and compared it with existing approaches, including Random Leaves Ordering (RAND-LO), Depth Leaves Ordering (DEPTH-LO), Depth Remaining Leaves Ordering (DEPTH-RELO), and our initial version, Close Remaining Leaves Ordering (CLOSE-RELO). By including CLOSE-RELO in the comparison, we aimed to assess the advancements achieved in our new approach. The results demonstrate that TDMA-CADH significantly improves channel throughput and reduces transmission delay while maintaining energy efficiency and network lifetime. These findings suggest that our proposed method can effectively enhance the performance of Wireless Sensor Networks in IoT applications.
