QoS Mapping in TDMA Tree Based Clustered WSN between Accuracy, Density and Bandwidth

Recently, there have been many efforts to develop wireless sensor networks (WSN), but no one can deny the fact that QoS support is still one of the least explored areas in this domain. In this paper, we present QoS support in WSN while highlighting the QoS mapping issue, a complex process in which QoS parameters are translated from level to level and we present a case study of a TDMA tree-based clustered WSN, where accuracy and density on the user level are mapped to bandwidth on the network level.
