Abstract: MWSNs need an efficient handling of mobility in all layers with respect to the sensor network protocol stack. 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.
