Examination of Energy Efficiency for MAC Protocol in Wireless Body Area Networks

Wireless body area networks are widely used for applications such as health care system, where wireless sensors (nodes) monitor the parameter(s) of interest. Sensors play a critical role in many sensor network applications. Mac layer operates on non-beacon and beacon enabled mode. The IEEE 802.15.4 standard provide two modes of connections: beacon enabled mode and non-offer transmission determinism. The non-beacon enabled mode does not suggest any assurance on traffic determinism. In this network an unslotted CSMA/CA channel access method is used beacon mode.
