Abstract

Most studies for mobile ad hoc network (MANET) assume fixed communication range/sensing range (CR/SR) without consideration of signal-to-interference ratio (SIR). In this Letter, we study the impact of SIR with different CR/SR settings by computer simulation. A model with the worst-case scenario, where we allow as many pair of sender/receiver nodes as possible in the simulated area, is developed in this study. Results show that transmission rules based on fixed CR/SR only may not be adequate for use in MANET due to low SIR.
