Abstract
Low data rate location/tracking UWB sensors have both location/tracking and communication capabilities, calling for novel routing and MAC strategies, in order to efficiently manage ranging and data transfer. In this paper, a particular configuration is adopted for routing and MAC, that are strongly correlated, because both are tied to the ranging module. Hence, a cross-layer design approach appears as the most appropriate. The routing algorithm, the e-GPSR, is a novel energy-awareversion of a geographic reactive multi-hop protocol, namely the Greedy Perimeter Stateless Routing (GPSR). The MAC scheme is a modified hybrid slotted-aloha time-hopping code division multiple access. Performance of the e-GPSR are evaluated as a function of design parameters of MAC and ranging module. Optimal values are provided for different degrees of network's mobility such that MAC and ranging are optimally designed to provide best performance of routing. © 2008 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
