Simulation based evaluation of DDH-MAC protocol for Cognitive Radio Networks

Abstract

Cognitive Radio (CR) has emerged as an intelligent technology to deal with spectrum scarcity. This research aims to simulate our already published research paper “DDH-MAC: A novel Dynamic De-Centralized Hybrid MAC protocol for Cognitive Radio Networks”. We have assessed the efficiency of the protocol by using a network simulation tool, OPNET 14.5 modeler. The simulation results were then compared with CREAM-MAC and F2-MAC protocols, and a comparative analysis have been evaluated and discussed. We show that the DDH-MAC protocol provides efficiency in time and energy which are the core objective features of CR Ad-hoc networks. Moreover, we also found that the delay of DDH-MAC could be reduced to much extent by increasing the DSSS data rate in physical characteristics.
