An Efficient Data Dissemination Protocol for Content-based Communication in Disconnected MANETs
Opportunistic Networking is a kind of communication in which hosts that compose the network must store, carry and forward a message and must keep as much messages as possible to increase the chance of sharing them to other hosts. In this type of network, nodes are updating continuously their cache according to their interest Thus deleting a message in a cache when its deadline is reached reduces the possibility1 of carrying and sending it to others host. According to some realistic scenarios a best may be interested in content that has just been discarded from a cache. Moreover, cache management in the same area of communication is important for it increases the delivery rate of a message. The actual paper presents a protocol that supports communication in sparse and disconnected Network and addresses the problems mentioned above by designing a content notification scheme and a forwarding decision algorithm based on the expiring time of message in disconnected Mobile adhoc network scenario. Experiments and simulations show that these two approaches of data dissemination we propose improve the content delivery rate and enable fast dissemination of messages.
