There exists a number of MAC protocols targeted for mobile scenarios. These include MMAC, MS-MAC and AM-MAC. These MAC protocols have in common that they seem to be evaluated only in simulation. This might indicate that these MAC are either too complex to use or they are not needed, at least for data collection, the major task of sensor networks. In this paper, the authors show that extending a traditional data collection protocol with lightweight, carefully selected mechanisms is sufficient to provide reliable data collection at low energy cost for mobile sensor networks where both sinks and sources move.
