Mobile Adhoc Networks (Manet)
Users can design, model and simulate wireless networks using Wireless Node for Single MANET, Wireless Node and Bridge
Node for Multiple MANET.
A drag & drop GUI enables users to quickly create the network and set properties with a simple right click &
MANET Protocol Capabilities
Network Layer protocols:
DSR - Dynamic Source Routing implemented as per RFC4728
AODV - Adhoc on Demand Distance Vector Routing as per RFC 3561
ZRP - Zone Routing Protocol as per Section 10 of RFC 2026
OLSR - Optimized Link State Routing as per RFC 3626
MAC Layer protocols:
- IEEE802.11e– Quality of Service
- Rate Adaptation – Minstrel, Generic
- CSMA/CA - protocol with RTS / CTS exchange
- BSS Type - Mesh
PHY Layer protocols:
- WLAN - IEEE802.11a / IEEE 802.11 b IEEE 802.11 g / IEEE 802.11 n / IEEE 802.11 ac / IEEE 802.11p as defined in IEEE 802.11 WLAN Page
- CSMA/CA protocol with RTS / CTS exchange. Infrastructure BSS and DCF mode
SNR / BER / PER Calculation
SNR is calculated by using the formula below
The bit error rate (BER) is the number of bit errors divided by the total number of transferred bits during a studied
time interval. The BER calculation is calculated using as SNR – BER tables for different modulation schemes. s
Rx Power Calculation
Received power is calculated by using the formula below

Source Code: Protocol Source C code with DLL interfacing for simulation in the loop debugging.
- File Transfer Protocol (FTP)
- Database Application
- Voice Traffic
- Video Traffic
- Custom Model: Users can develop custom application model based on Packet size and inter-arrival time available
in the following probability distributions
- Peer to Peer
- Application encryption using AES and DES algorithms
Network Metrics, Link metrics Application metrics, Protocol Specific metrics for each protocol, and Forwarding
Metrics include throughputs, Delays, Data & control packet information and protocol specific Results
Graphical plots over time for link and application throughputs and TCP congestion window
Detailed Packet Trace (All Components)
Detailed Event Trace (All Components)
- All protocols have detailed packet level trace generated in a tab ordered .txt, .xlsx format.
- Packet trace contains the details of packet like packet number, source, destination, arrival time, payload, overheads
- All protocols have detailed event level trace generated in a tab ordered .txt, .xlsx format.
- Event trace contains the details of event like Event Time, Event Type, Device Type, Application ID etc.
Dynamic Metrics: Dynamic metrics allows users to monitor the value of a parameter over simulation time.
Command Line Interface – CLI
- CLI mode of running for more concise and powerful means of control
- Facilitates use of automated scripts for running batch simulations
- Model network configurations using XML based configuration files
- Animates packet flow over wired and wireless links, as well as node movement
- Color variation for data, control and error packets
- Animation settings via play, pause and time-slide
- 25+ info fields now available with packet animator.
- Wide range of animation options including plots, battery level, graphs, tables and more.
- Visualization with inbuilt graphs for link and application throughput.
- Graph controls with Colouring, XY Axis settings, Grid Settings, Zoom and more.
Simple MANET network in NetSim:
Multiple MANET (with Bridge Node)
Bridge Node acts as a bridge/interface/gateway between multiple MANETs.
Packets from MANET-1 are routed to MANET-2 (and vice versa) via the Bridge Node
R & D Areas and Projects in NetSim:
- IDS (Intrusion Detection System)
- Sinkhole attack
- Secure AODV
Interfacing with Wireshark and MATLAB
