摘要: This paper deals with the positioning performance of 3-Way ranging protocol (3-WR) in a wireless body area network (WBAN). The purpose is to propose new cooperative algorithm improve number estimated positions conditional permutation on-body anchors. To do so, we first evaluate and analyze success rate under realistic mobility scenario using two scheduling strategies: Broadcast single node localization (P2P-B) aggregated broadcast (A\&B)) medium access control (MAC) layer based on time division multiple (TDMA). 3-WR estimates distance between nodes placed transmission three packets. impulse radio ultra wideband (IR-UWB). However, these transactions can be lost through WBAN channel leading into ``bad service.'' We consider physical IR-UWB different channels: (1) an empirical theoretical model CM3 path loss (Anechoic chamber), (2) simulated calculated by ray-tracing PyLayers simulator, (3) experimental obtained measurements. Our results show that affects decreases as function sensitivity threshold at receiver. solved long short term analysis for choice virtual anchors increase performance.
