With recent advances in wireless networking, Wireless Body Area Networks (WBANs) became practically feasible. Body Area Networks are defined by the IEEE 802.15.6 standard. However, IEEE 802.15.4 MAC can also be used for WBANs as it is cheap and simple. This paper presents a study about the standards IEEE 802.15.4 and IEEE 802.15.6. In this paper, both IEEE 802.15.4 and IEEE 802.15.6 are explain...

Wireless sensor networks are often located in areas where access to them is difficult or dangerous. Today, in wireless sensor networks, cluster-based routing protocols by dividing sensor nodes into distinct clusters and selecting local head-clusters to combine and send information of each cluster to the base station and balanced energy consumption by network nodes, get the best performance ...

Wireless Body Sensor Networks (WBSNs) involve a convergence of biosensors, wireless communication and networks technologies. WBSN enables real-time healthcare services to users. Wireless sensors can be used to monitor patients’ physical conditions and transfer real time vital signs to the emergency center or individual doctors. Wireless networks are subject to more packet loss and congestion. T...
