ASRQ: Automatic Segment Repeat Request for IEEE 802.15.4-Based WBAN

Abstract– In the first place, wireless body area network (WBAN), In addition, Mobile Computing high data reliability and long operating time are important requirements. Mobile Computing retransmission process of the default Automatic Repeat reQuest (ARQ) mechanism in IEEE 802.15.4 is a suitable method to ensure the mobile computing data reliability of WBAN communications wireless body area network , In fact, frame loss can occur frequently. In the final analysis, Mobile Computing retransmitting the entire DATA frame is energy inefficient due to the fact that the most of payload data In order to, lost frames are only partially corrupted.In this case, proposes the automatic segment repeat request scheme for the IEEE 802.15.4-based WBANs.In Brief, the size of the retransmitted frames, which improves frame reception rate and decreases the amount of transmitted traffic, In effect, Mobile Computing Wireless body area network, energy consumption Mobile Computing . As the result, experiments using a real IEEE 802.15.4-based WBAN test bed In other words, the proposed method provides higher transmission reliability and lower power consumption than the default IEEE 802.15.4 ARQ mechanism.
