In wireless sensor networks the energy efficiency can be improved with path constrained sink mobility. But collecting data from the nodes deployed randomly by the mobile sink as limited communication time due to constant speed of the mobile sink in the path constrained approach. This affects the amount of data collected and the energy consumption of the network. To overcome this issue, a novel data collection scheme called MASP is proposed. MASP is implemented as a two phase communication protocol base on zone partition. The authors' results are validated and simulated using OMNET++.
