Dear Ankur Bang,

maybe some of my figures can help - see:

• The Figures in Chapter 17.1; Pages from 917 to 933

Internet of Things - Technical Basics and Protocols

• The Figures 1, 2 and 7 in: "Protocol structure of 6LoWPAN devices"

Best regards and much success

I am aware of open-source tools and implementations concerning your points (1. infrastructure, 4. Discovery, 5. Data Protocols). Indeed, Contiki-OS (http://www.contiki-os.org/) has a full network stack supporting your point 1. It has also discovery mDNS/DNS-SD mechanisms implemented along with CoAP and MQTT Data protocols. Other IoT OSs such as RIOT and OpenWSN provide similar functionalities.

From my experience, I would recommend you go with NetSim (https://www.tetcos.com). Of the listed protocols it covers 

6LoWPAN, IPv4 / IPv6, LPWAN 802.15.4, COAP, RPL, Wi-Fi along with many other nice features for IOT R & D.

Hi,

I would recommend TETCOS NetSim. It is used widely in Thailand for R & D on IOT

Dear sir

you can check these simulations:

The best choice for IoT simulation would be Netsim by tetcos. But even Netsim doesn't have all the base base models for the list you have given.

Can consider Netsim and MATLAB, Contiki based Cooja Simulator.

Cisco Packet Tracer is one of the interesting tools for IoT simulation work. Had experience using packet tracer for various IoT project.

I would also recommend NetSim for network level simulation and MATLAB for link level simulation
