Body area wireless sensor networks (BANs) are a key component to the ubiquitous healthcare revolution and perhaps one of its most challenging elements from a communications standpoint. The unique characteristics of the wireless channel, coupled with the need for extreme energy efficiency in many healthcare applications, require novel solutions in medium access control protocols. We present the main...
We consider a body area network (BAN) setting in which sensor nodes send data to a common hub regularly on a TDMA basis, as defined by the emerging IEEE 802.15.6 BAN standard. Our previous work has established the benefits of variable TDMA scheduling in this setting, where the order of communication with nodes in each TDMA round is determined on the fly by the hub, based on the actual outcomes (success...
This work outlines challenges and requirements of designing a Medium Access Control (MAC) protocol for Body Area Networks, where sensor nodes send their measurement data to a central gateway device (also known as sink or hub) regularly on TDMA basis. While a number of protocols has already been proposed specifically for BAN's, they fail to account for unique characteristics of wireless channel around...
We consider a typical body area network (BAN) setting in which sensor nodes send data to a common hub regularly on a TDMA basis, as defined by the emerging IEEE 802.15.6 BAN standard. We explore variable TDMA scheduling techniques that allow the order of transmissions within each TDMA round to be decided on the fly, rather than be fixed in advance. Our approach is related to opportunistic scheduling...
