摘要: In this paper, we highlight the extent of effects topological specificities on deployed solutions, which can be useful to refine already proposed models as well carry out protocol tuning or adjustments. We present, an intensive experimental study wireless Link Quality Indicator (LQI). Using Moteiv's Tmote Sky sensors, multiHopLQI algorithm TinyOS in various network configurations: homogeneous and heterogeneous; straight-line grid topologies with transmission power levels distances. Initially, LQI time-varying try understand relationship between level, distance link quality present how some random disturbances due external (physical changes) internal phenomena (node movement,power variation) may affect dynamics network. Later, address impacts side position level important nodes like Base Station such based algorithms.
