초록
The IEEE 802.15.4 LR-WPAN specifies low cost, low energy, low rate transmission of 20-250kbps and mostly within 10 meters of diameter. Its specification of PHY and MAC layers can be used as the lower layers of ZigBee technology [4]. As many applications for short range, wireless networking environment have been developed, the need for voice transmission over the IEEE 802.15.4 LR-WPAN has been also increased. This paper studies the possibility and effectiveness of voice transmission over the IEEE 802.15.4 LR-WPAN by intensive simulations using ns-2 simulator [6], and shows several use cases as its applications by their implementations. ©2008 IEEE.
