The requirement to handle mobility adds another dimension to sensor network protocols, in addition to conservation of energy and computation resources. Accordingly we propose to design a mobility aware MAC protocol for providing energy efficiency and stability for MWSNs. Initially a link status history is maintained while the MoX-MAC nodes send their data to static nodes. From this the link quality issue is addressed. If the link quality is poorer the MoX-MAC will drop or ignore the packet. Next in case of energy consumption the nodes enter into the periodic sleep-awake duty cycle. If the link quality is less than the threshold value, the corresponding communication is blocked.
