A Survey on Data Dissemination to Mobile Sink Groups in Wireless Sensor Networks

In past few years, the domain of data dissemination in wireless sensor networks has been the area of interest to be researched. Whenever there is context of mobile sink groups, the data delivery relates to a complex mechanism because mobile groups have a feature to move in a collective manner. On the basis of previous work, generally the mechanism of flooding is adopted to disseminate the data on the basis of the predictive location. But, as it is known that the mobility issue in wireless sensor networks tends the mobile sink groups to a new location. On the name of prediction, we can only get an instance of their location. Eventually, it leads to a negative impact on the data flooding to the desired nodes, which harms reach ability and energy efficiency. This paper presents a survey of data dissemination schemes of various approaches along with the comparison among them to configure out the differences.
