POWER-SAVING TDMA MAC FOR WIRELESS BODY AREA NETWORKS

摘要

A time division multiple access (TDMA) media access control (MAC) protocol is provided for wireless body area networks (BANs). In particular, in some embodiments the described network devices utilize a reservation-based power saving polling (RESP) MAC protocol for communication. The RESP MAC can be configured to provide methods for emergency event handling of both bursty data and streaming data.
