A wireless body area network aims to provide real-time and ubiquitous body monitoring to perform autonomous early prediction

diagnostic

and tracking the response of the body to treatments

becoming a hotspot of research and application. As the importance of WBAN in daily life has become increasingly prominent. The standard IEEE 802.15.6 was published in 2012

which was specifically designed for WBAN. This article focuses on the resource allocation problem in and between WBAN

considering the heterogennity of WBAN and sensor node

analyzing the research status and the insufficient of resource allocation. Finally

several key issues of resource allocation problem in and between WBAN are discussed and future directions are pointed out.
