Key components of a WBAN
A WBAN network structure consists of several tiers of interconnecting net-
works. The work presented in this topic pays attention to the communication
between sensor nodes and an immediate parent node of the sensor nodes, which
can either be a central coordinator or a gateway router. This communication is
named as sensor tier communication hereafter. Typically, short-range wireless
