“…In concordance with [ 24 ], the work in [ 16 ] shows also that UWB characteristics should be taken into account in the MAC layer for channel access, scheduling, and error control wherein the low duty cycle and low power transmission reduce the probability of collisions between pulses and interference.…”

“…UWB [ 16 , 17 ]—with coding efficiency of 97.94%, data rate up to 250 Mbps, and nominal range of 10 meters in addition to its immunity to multipath propagation and precise positioning capabilities—has the potential to enable low power consumption, high data-rate of short range wireless communication and seems to be a promising candidate for the physical layer standard of WMSN. UWB spreads the information over a large bandwidth, about 20% of the center frequency or more than 500 MHz.…”

“…Instead of adopting a single routing path for data delivery, using multiple independent paths simultaneously to split the traffic will allow to achieve higher aggregated bandwidth [54]. In the meantime radio technologies with potentially higher bandwidth, such as the ultra-wideband (UWB), can also be used in WMSNs [77,78].…”

“…η ακρίβεια (µερικών εκατοστών), πολύ χαµηλή κατανάλωση ισχύος (ισχύς εκποµπής κάτω από τα 0 dBm, ήτοι ∼37 µW), εκτεταµένη εµβέλεια και ευρωστία έναντι της παρεµβολής και της κινητικότητας[KGTP07b],[KGTP09c].Στην υπερευρυζωνική τεχνολογία εκπέµπονται αδιαµόρφωτοι παλµοί πολύ µικρής διάρκειας (<1ns) οι οποίοι επιφέρουν ένα πολύ µεγάλο εύρος Ϲώνης σήµατος µε στιγµιαία ϕασµατική κάλυψη που ξεπερνάει τα 500 MHz[Com02]. Το πρότυπο IEEE 802.15.4a καθορίζει δυο προαιρετικές εκδόσεις σηµατοδοσίας : α) το Impulse-Radio (IR) UWB και ϐ) το chirp spread spe-ctrum -CSS.…”
