In a typical wireless body area network data packet loss is high due to the movement of sensor nodes attached to the body limbs. To address this problem we propose a novel position-aware MAC protocol (PA-MAC) in the wireless body area network which considers the nodes' relative positions to the coordinator when the subject is moving. We modify the 802.15.4 MAC protocol so that sending nodes only transmit the packets when they are in their best relative position to the coordinator to mitigate the effects of path loss and shadowing in areas around the body where they have the least signal strength. The experimental evaluation shows that the proposed method increases the delivery ratio for sample rates below 20p/s as compared to the MAC 802.15.4.
