INET MANET Simulator

INET MANET Simulator

Introduction of INET MANET Simulator

               In our daily life, we are connecting with technology at every second in our life. This technology makes our life more beautiful and useful to learn modern technology and also it makes good bond by communication and sharing the information. So, this is mandatory to know our modern technology and how it works. “In this article, we will discuss the INET MANET Simulator and protocols of that simulator and also gain knowledge about AODV, DYMO, DSDV, and GPSR also.”

               INET Simulator is useful for getting feedback from the user to the network and here we implement INET programming in OMNeT++ platform this is an open-source platform and suitable for both wired and wireless networks. Then this kind of INET simulator is mainly useful for validating a new protocol and designing a new protocol or used when we built a new scenario. INET MANET is the extended technique of the INET Simulator.


               MANET are also known as the connection of multiple mobile wireless nodes for an ad-hoc network. The network topology of MANET is a chance to change an overall process time and it gives the nature of mobile phones to the nodes in the network. MANET routing protocols are mainly built for mobile networks and are also useful for the lack of security infrastructure of the stationary nodes. 

               The above content insists on what is MANET and then we will discuss INET MANET and its entire details. We are having several projects based on MANET and we have new project ideas also.

INET MANET Simulator

  • It is extended from INET Simulators 
  • INET MANET is a part of the INET 3. x branch and it has some additional protocols and modules when compare with the INET simulator.
  • Now a day, INET is extended up to INET MANET 4. x branch and it is useful to ad-hoc networks also.
  • For every simulator or any other network, protocols are important without protocol the simulator does not work properly. Then we will discuss routing protocols that are used in INET MANET Simulator and their goal.

Goals of routing protocols for INET MANET Simulator:

INET MANET Simulator is developed by using OMNeT++ (Object Modular Network Testbed in C++) and the MANET (Mobile Ad-hoc Network Protocol) routing protocols are mainly used for the mobile communication. Here, we consider some simulation examples for MANET routing protocol operators given below,

  • Proactive (DSDV)
  • Reactive (AODV)
  • The location-based routing protocol (GPSR) DYMO

There are some simulation models and represent the INET MANET Simulator. Then we need to know each of these simulation application in depth. First, we will discuss DSDV it is a proactive routing protocol. Let us see further details of DSDV.

Working of DSDV 

            We also know DSDV is the proactive MANET routing protocol and it is also known as Table driven protocol and it ensures the network routing information is up to date and maintains that kind of information.

  • Here, the Routing entry follows some set of parameters there are,
  • Destination IP address
  • Sequence number
  • Total hop count
  • Next hop count.
  • Each node in DSDV finds the best and optimal solution for reaching the destination because it maintains a Routing table.
  • For considering routing table it represents all the possible destination entries if it is indirect to the neighbor’s or directly to the neighbors. 

How to update routing information in DSDV

DSDV gives always the best route for the nodes because it frequently updates the routing information. There are two ways for updating a routing protocol there are,

  • If any changes in the routing table it gets a small update for Nodes broadcast.
  • Update infrequently in the routing table for Nodes broadcast.

If nodes are getting updated their routing table it reaches a better route. A better route can be found out using two ways,

  • High Sequence number
  • If the sequence number is the same it has a lower hop count.

DSDV takes less time for sensing the data, routing entries are updated frequently and messages can be sent any time because the routing process maintains continuously. So, DSDV said to the proactive routing protocol. This is a brief explanation about DSDV then considering another simulation example that is AODV.

Outline of AODV (Reactive) Protocol 

In AODV packets are sent frequently to the router and the router maintains the packet details based on their demand of the network. So, AODV is called an ad reactive INET MANET protocol or on-demand routing protocol. When the next-hop node reaches the destination until the router maintains the routing table in AODV and if the time out for routing process then cannot send the packets.

Process of AODV Protocol 

  • RREQ multicast message is used in AODV for finding the best route to reach their destination. If initially, one node needs to send the packet. Then the router did not know the destination. Using the RREQ message the best path will find out.
  • The neighborhood node maintains the record it contains sending source for the message and which node is forward the packets is monitored until the destination of the message.
  • Finally, the destination node gives a reply with the RREP multicast method and sends it back to the source.
    • RERR: Route Error
    • RREQ: Route request
    • RREP: Route Reply

  These are some message type that is used in the AODV routing process and explanation of the main process in AODV. Then we will see about multicast message mechanisms, how the message arrives and what are the steps followed in these mechanisms.

Multicast message mechanisms

               Here routers are considered as an intermediate node that node has an RREP message. When the message is found that node will consider as a destination and its merge with the route is already exists. If the RREP message arrives at the source node then the best routes are created and start to communicate between source nodes to the destination nodes.

  • In case, if any break in the link is found in the route, message forwarding is not possible.
  • In this critical situation, a multicast message that is RREP is useful to detect the break and solve that problem for communication.

In general, AODV has less route maintenance and new routes can be found if any break in the link. So, AODV is said to be a reactive MANET routing protocol. Then we go to the interesting topic that is GPRS. It is a widely used technology in recent times for detecting and tracking the location.

Define GPSR

GPSR is defined as a location-based routing protocol it takes input in the form of geographical data and regarding finding the routes. Nodes in GPSR must contain the geographic coordinates and addresses of a neighbor node if the node is in a specific range of communication.

  • Context of routes: local information of the node, position of nodes, and communication range.
  • Packet Transmission: In the transmission phase overhead parts are deleted for reducing the beacon timer.
  • Table Entry: If the link is failure that node deleted automatically and nodes are attached location and forward packet details
  • Beacons: Using beacons each node are advertised their periodic location and at the same time the level of receiving beacons is increased the node assumes itself it is out of range and that node will be deleted from the table entry

Protocol Operation Modes

               In this mode, packets are getting routed using locations and coordinates of the particular location. And the destination of receiving nodes is based on the IP addresses of the packets. This protocol operates based on two modes. There are,

  • Packet mode: In this mode, neighborhood nodes are created by it using a planar graph based on the number of vertices (communication links) and edges represent nodes and location of their nodes.
  • Greedy mode change: This node is geographically closed to the destination node that node consider as a neighbor node for packets transmission

This GPRS is useful to find the location of neighborhood nodes. Now a day, this technology is mostly used to detect a device and more than track systems. Then we will discuss DYMO.

Define DYMO

               For the extension of the INET MANET simulator, it is useful to learn to activate new routes at the MAC layer and it also has a promiscuous mode.

  • Sniffer RREP packets: It consists of an ARP-type table to match the neighbor’s MAC address to the corresponding IP address.
  • RREP: This kind of RREP packet do not forward with the original IP address it is possible to achieve read and listen to all RREP packets

And these are some simulation applications used in INET MANET Simulator. Finally, we will see about some simulation parameters for INET MANET in the OMNeT++ environment.
