Performance Analysis of IEEE 802.11 and Sensor Medium Access Control (SMAC) Protocols for Wireless Sensor Network with Considering the Effects of Hidden Nodes Problem

Abstract

Wireless sensor networks (WSNs) are one of the most important wireless networks. Its wide applications range such as military applications, industrial applications, agricultural applications, industrial applications, and other various applications make it the focus of attention for many researchers. Two MAC layer protocols were studied in this paper, considers the effects of hidden node problems. Nodes are disseminated randomly in different spaces with different numbers. Residual Energy, Good-put, Throughput, Packet delivery ratio (PDR), First and last node dead on the network, and Average Delay are the performance metrics used in this paper. Two protocols were chosen for this study are Sensor Medium Access Control (SMAC) protocol and IEEE 802.11 protocol. Different scenarios were implemented in this study. The goal of this study is to analyse with a graphical view what is the best number of nodes to be disseminated on a specific field space depending on the required performance metric. The protocols are constructed and examined using Network Simulator version 2 (NS2). Results show that the best energy conservation belongs to the SMAC protocol while low delay time and high PDR have belonged to IEEE 802.11 protocol.
