It is of utmost importance to conserve battery energy to the maximum possible extent in WBAN nodes while collecting and transferring medical data. The IEEE 802.15.6 WBAN standard does not specify any method to conserve energy. This paper focuses on a method to conserve energy in IEEE 802.15.6 WBAN nodes when using CSMA/CA, while simultaneously restricting data delivery delay to the required value...
Emergency nodes, i.e, nodes with priority 7 as per 802.15.6 standard play a very important role in facilitating the immediate transfer of information during life threatening situations. These nodes should relay critical information with utmost reliability and in the shortest possible time. IEEE 802.15.6 provides the necessary functionality to these nodes by adapting the contention window sizes as...
It is of utmost importance in a wireless body area network (WBAN) to improve the lifetimes of devices, while restricting latencies within allowable limits. These two demands are often conflicting, and a method to ensure fairly good values for these parameters with a view to satisfying the requirements of the WBAN application would be highly desirable. We consider CSMA/CA option of the medium access...
Lifetimes and latencies of devices in wireless body area networks (WBANs) that monitor the health conditions of patients largely determine their utility under such a setup. It is seen that the medium access control (MAC) used in the WBAN can play a significant role in the network lifetime and the quality of service (QoS) it can provide. IEEE 802.15.6 standard for WBAN includes different MAC options:...
Wireless body area network collects information from medical devices that monitor the physiological parameters of a human body. Energy constraints of medical devices and bounded latencies of medical applications are the chief QoS requirements of WBANs. With the standardization of the WBAN network, viz. 802.15.6 standard, mechanisms for medium access have been specified which can be skillfully manipulated...
Wireless Body Area Networks (WBANs) can use different types of medium accesses namely CSMA, scheduled, polling, or a combination of these techniques. These access methods are specified in IEEE 802.15.6 standard for WBAN. Most of the studies done so far on medium access methods in WBAN have been related to CSMA and scheduled access. Polling is also specified in the standard as a medium access method...
