Abstract: In this paper the feasibility of contention-based medium access control (MAC) protocols using impulse radio technology for medical ICT scenarios is shown. The particular scenario refers to a hospital waiting room in which people enter wearing a number of sensors for continuous monitoring of health status. The evaluation of the feasibility is founded on the implementation of slotted Aloha (S-Aloha) and preamble sense multiple access (PSMA) MAC protocols, the physical layer characteristics and the non-coherent receiver scheme for impulse radio ultra wideband (IR-UWB) in the network simulator Opnet. Simulated throughput and delay performance under Poisson traffic assumption are compared with analytical results for validation purposes. The simulation of the medical scenario, not easily tractable by analysis, accounts for important characteristics like capture effect and different bit rates of the sensors that monitor various vital functions. The results show that the used MAC protocols a re scalable within the scenario constraints and PSMA exhibits a better delay performance than S-Aloha. (More)
