The general context of the present memory is about the cross-layer optimization of wire- less sensors networks based on ultra wide band technology UWB. The proposed solutions en- sure the share and the efficient allocation of spectral and temporal resources, the optimization of the energy consumption and the support of multi-constraints quality of services QoS. The most challenging issue is providing a tradeoff between the resource efficiency and the multi- constrained QoS support. For this purpose, we proposed a new Wireless Hospital Sensor Net- work (WHSN) three-tiered architecture in order to support large-scale deployment and to im- prove the network performance. Then we designed a channel allocation scheme (UWBCAS,) and a prioritized m...
