N2 - This paper present a Data Dissemination strategy based on Time Validity (DDTV) to deal with time-sensitive contents in opportunistic networks. Time sensitivity refers to the constraint that the content must be delivered to the destinations within a given time frame called time validity. A content delivery fails when the time constraint cannot be satisfied. Thus, DDTV exploits user's mobility and historical travel records to obtain the delivery probability of contents to its destination within the designated time. Then, the expected delivery probability obtained at each time interval is used to select the most suitable content carrier that can satisfy the contents time validity. To further increase the content delivery probability, a successor is selected to continue the delivery of the contents. Simulations show that DDTV has a remarkable improvement when dealing with time-sensitive contents on delivery rate and delivery efficiency with lesser transmission overhead when compared to other existing methods.
