Investigation of Data Dissemination using Publish Subscribe Approach In Opportunistic Network

Opportunistic Network is a kind of communication technology that operates on rapid changes network topology. The main challenge in Opportunistic Network is to identify the best path to deliver a message to the target destination. This is due to no definite paths exist between source and destination....
