Revisiting the Transmission Range Model in Mobile Networks Based on IEEE 802.11a/g

Do the people correctly simulate mobile networks like MANETs and DTNs? Is the simulation result of mobile networks reliable? In this paper, the authors start from these questions and point out the critical defect on the widely used transmission range model which is on the basis of mobile network simulations. As an alternative, they propose a realistic transmission range model considering the mobility and channel estimation error, and confirm that the simulation results can be completely different from what they have believed so far. They claim that the network protocols known best in mobile networks should be revisited with the proposed model.
