Protokol media access control (MAC) berperan menjamin keberhasilan transmisi data antar sensor nirkabel dan konsumsi daya pada Wireless Body Area Network (WBAN). Penelitian ini membandingkan unjuk kerja dua buah protocol MAC, yaitu T-MAC dan ZigbeeMAC pada sistem WBAN, pada laju kedatangan paket (λ) yang berbeda. Hasil simulasi menunjukan bahwa pada jaringan dengan λ rendah tingkat keberhasilan pengiriman paket antara protocol T-MAC dan ZigbeeMAC mencapai rata-rata 90% dari throughput maksimal walaupun pada kondisi tersebut kinerja ZigbeeMAC memiliki nilai lebih baik dibanding T-MAC. Pada laju kedatangan paket tinggi, throughput pada T-MAC memiliki perbedaan yang signifikan terhadap ZigbeeMAC. Pada keadaan terburuk troughput T-MAC adalah 88% dari throughput maksimal sedangkan Zigbee menurun hingga 43% dari throughput maksimal. Kosumsi daya pada ZigbeeMAC cenderung konstan untuk setiap laju kedatangan paket sedangkan pada T-MAC meningkat sejalan dengan pertambahan laju kedatangan paket.

Wireless body area network is a promising technology that brings healthcare to a new level of personalization. The applications of wireless body area network are not limited to healthcare monitoring applications but vastly used in entertainment applications. The applications are emerging at a fast pace and attract the attention of researchers. IEEE 802.15.6 provides a communication standard which specifies the physical layer and media access control layer operations for wireless body area networks. A fixed superframe structure is used for handling of heterogeneous traffics of wireless body area networks through pre-defined user priorities. This leads to inefficient use of superframe time duration because of fixed time phases for different types of data traffic. In this article, a novel group-based classification of traffic is introduced to avoid contention and inefficient use of superframe duration. A group-based media access control is developed to adjust the superframe duration according to high priority traffic whereas the rest of the traffic is controlled using node-based buffering. The experimental results showed that the proposed media access control outperformed adaptive beaconing medium access control and priority media access control, in terms of stability period, delay, throughput, transmission loss, and residual energy.

The IEEE 802.15.6 standard emerged as the most suitable standard that fits the special requirements of wireless body area networks. It provides flexibility to designers by recommending the use of several medium access control layer techniques, but does not specify how to combine some or all these recommended techniques to form the most efficient wireless body area network medium access control for a specific scenario. Our goal here is to design a wireless body area network medium access control that provides an optimal combination of these basic techniques that are available in the standard, by taking into consideration the variability and heterogeneity of the sensors. The performance of the proposed techniques is evaluated using some of the standard performance measures such as throughput, delay, and energy consumption.
