Ad Hoc Routing Under Randomised Propagation Models
Hugo Miranda · 2010
The deployment of mobile ad hoc networks is dicult in a re- search environment and therefore the performance of protocols for these networks has been mostly evaluated on simulators. A simulator must replicate realistic conditions and one of the most dicult a spects is the radio signal propagation model. The literature shows that many perfor- mance evaluations were conducted using propagation models that are not realistic for the expected application scenarios. This paper shows that the non-determinism present in some radio propagation models induce randomness which may compromise the performance of many protocols. To demonstrate the problem, this paper compares and discusses the per- formance of some routing protocols under dierent propagat ion models.
