1000 simulation samples are collected from OPNET
simulation to train the classifier, where half of the samples are collected under CSMA/CA protocol while the rest half are under TDMA protocol.
LEACH-SM is evaluated using Zigbee nodes in OPNET
Network Simulator , which is a well-known discrete event simulator.
The data throughput of 65 Mbps base and 600 Mbps maximum is selected for OPNET
Qing and Cong  explain that the OPNET
modeler provides different levels of modeling, depending on the requirements of the simulation.
In order to analyze the performance of the proposed protocol, we implement the protocol simulation on OPNET
In the simulation, the delay, and packet loss of each subqueue (using built-in statistic functions in OPNET
) are measured.
the throughput is defined as the total number of successfully transmitted data packets per simulation time.
Optimized network engineering tool (OPNET
) modeler academic edition version 17.5 was used for the simulations.
There are several established tools for the simulation of wireless networks protocols, including ns-2 , OPNeT
Modeler  and GloMoSim .
