Wireless body area sensor networks give them services by continuous, remote and non-invasive monitoring. This network system should monitor various physiological parameters of a person for a long period of time. Wireless body area sensor network requires energy efficient communication protocols to minimize the energy consumption and hence for increasing the life time of whole system. This paper explain the effects of adding a relay network in conjunction with the sensor network for reducing power consumption of sensor nodes when transmitting data to the base station.
