Performance Analysis of IEEE 802.15.4 and TDMA Protocols in Wireless Sensor Network with Considering the Effects of Hidden Node Problem

Abstract

Wireless sensor networks (WSNs) offer a wide range of applications, including agricultural, industrial, military, and a variety of different applications, providing it a suitable option for researchers and students to research. The implications of the hidden node problem are investigated in this work on two different MAC protocols with different field distances and node densities. This research determines the optimal number of nodes to disseminate in a certain field distance based on the desired performance metrics. Throughput, Goodput, PDR, Average Delay, Residual Energy, and the first and last node dead time in the network are the six performance measures evaluated. In this work, the IEEE 802.15.4 protocol in non-beacon mode and TDMA are used. For this investigation, eight different scenarios were proposed and implemented. The proposed scenarios are built using NS2. The findings show that TDMA provides the optimum energy conservation as well as a long delay time and a high PDR. A graphical view of the results was made to make it easier for result analyses. This paper provides what is the best MAC protocol to be used with specific field distance and specific performance metrics.
