Analysis of CSMA/CA mechanism of IEEE 802.15. 6 under non-saturation regime
IEEE Transactions on parallel and Distributed Systems, 2015•ieeexplore.ieee.org
We have developed an analytical model for a non-saturated IEEE 802.15. 6 wireless body
area network (WBAN) operating under an error-prone channel. The most suitable vehicle for
improving network performance was found to be the choice of access phase lengths based
on traffic loads for different user priorities (UPs). It was also found that the deployment of
exclusive access phase (EAP) is not necessary in a typical WBAN; in fact, short exclusive
and random access phases (EAP and RAP, respectively) lead to inefficient use of available …

The most suitable vehicle for improving network performance was found to be the choice of access phase lengths based on traffic loads for different user priorities (UPs). It was also found that the deployment of exclusive access phase (EAP) is not necessary in a typical WBAN; in fact, short exclusive and random access phases (EAP and RAP, respectively) lead to inefficient use of available bandwidth. We have also found that four user priorities (out of the eight available) typically suffice to achieve even the most stringent requirements for WBAN performance.
