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

Provided by: International Journal of Computer Applications Topic: Networking Format: PDF
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.
