This bachelor’s thesis called "Verification of MANET routing protocol potentials in OPNET modeler enviroment" is focused on MANET network. The first part is introducing routing protocols that are most used in OM. The second part of that work is strictly aimed to DSR routing protocol, its parametrs and configuration in OM. There is also discribed DSR process model. The most important part of that thesis is extension of data unit of DSR protocol and use that unit for transmision of information that are stored inside of its structure. As the extended unit was chosen Route Request packet that include new variable. The simulations are proving succesfull traffic of extension packet between nods with ability to store/read from RREQ extended struct...
