Development and Verification of Simulation Model Based on Real MANET Experiments for Transport Layer Protocols (UDP and TCP)
There is a lack of appropriate guidelines for realistic user traces, mobility models, routing protocols, considerations of real-life challenges etc. for general-purpose Mobile Ad-hoc NETworks (MANET). Therefore it is difficult to reproduce any typical scenario in reality apart from simulation. In this paper, four laptops are used in an open field environment in four scenarios to evaluate the performances of ICMP Ping and TCP based streaming video applications using real OLSR implementation in an IEEE 802.11g wireless network. Corresponding simulations are developed in ns-2 by tuning wireless signal propagation model parameters and by setting the real experiment parameter values. Difficulties faced to regenerate real-life scenarios have been discussed and the gaps between reality and simulation are identified.
