  Power and energy consumption is a fundamental issue in Body Sensor Networks
(BSNs) since nodes must operate properly and autonomously for a certain period
of time without battery replacement or change. This is due to the fact that the
sensors in BSNs are either implanted in the body or are in very near position
to the body. Thus, the duration of replacing the batteries should be of utmost
importance. Most of the existing researches suggested the development of a more
improved battery cells or developing an energy aware routing protocol to tackle
the energy consumption in WBSN. But this is not the case as most energy
consumption in WBSN occur as a result of mobility in routing and sensor node
placement. Therefore, improving the battery cells might not solve the energy
consumption in WBSN.
