OMNET++ is a component based modern open source discrete event simulator architecture. We ensure OMNET++ framework to represent specific application area to create various simulation model. We offer M.TECH thesis in OMNET++ which create framework to support mobile and wireless simulation. We provide MIXIM and simulation framework under OMNET++ to simulate wireless and mobile networks. We ensure support all M.TECH students do their academic projects with OMNET++ simulation under network domain.
We provide MIXIM simulator with environment global parameter such as size, 2D and 3D. We use object to model environment with object house and object wall. We adopt object manager to decide interfering objects in simulation. We deploy connection manager which manage dynamic connection among various objects. We establish signal quality based on interference and mobility by using connection manager.
Modules in MIXIM:
We evaluated more than 80+ projects in MIXIM framework. We use node modules to design application, network, MAC and physical layer based application. We group MAC & physical layer as single Nic module. We consider node with multiple Nic module in Bluetooth, 802.11 radios and GSM.
We consider mobility module to provide responsible for movement object within simulation environment. We propose battery module to model energy reservation node. We model communication, mobility related energy consumption and processing by battery module. We practice utility model for statistical data collection and inter modular data parsing. We identify location & energy level by utility module.
Elements associated with wireless & mobile networks:
- Mobile users are attached to network by base station.
- We use cell to cover geographical region.
- We handle cell connection to wide area network by mobile switching center.
- Air interface ensure physical & link layer protocol among mobile & base station.
- We use base station as access point which is an analogous standard of 802.11 AP.
Routing in mobile networks:
We implement routing in mobile network from science direct papers which advertise permanent address of mobile nodes by routing table exchange. By routing table we indicate location of each mobile node.
We categories routing in end system network as:
Nodes get foreign address of mobile send directly to mobile nodes.
Communication from corresponding to mobile nodes by home agent & then it will forward to remote.
Handoff in mobile network:
We use handoff to create route by new base station which does not have interruption. Handoff occurred due to discontinue of connectivity, load balance and less battery.
Protocol in mobile network:
We refer mobile IP as RFC 3220 and contain features as foreign agents, care of addresses, home agents, encapsulation and foreign agent registration. We use agent discover, registration with home agent and indirect routing of datagram components are used in mobile IP. Home network contain home location register & database with network contain permanent cell phone profile information and current location. We determine visited network contain visitor location register (VLR) database ensure entry for each user currently in network.
