ABSTRACT
Abstract:
An intermittently connected network (ICN) is defined as a mobile network that uses cooperation between nodes to facilitate communication. This cooperation consists of nodes carrying messages from other nodes to help deliver them to their destinations. An ICN does not require an infrastructure and routing information is not retained by the nodes. While this may be a useful environment for message dissemination, it creates routing challenges. In particular, providing satisfactory delivery performance while keeping the overhead low is difficult with no network infrastructure or routing information. In this presentation, message fragmentation is used to improve the delivery rate in an ICN. The cumulative distribution function (CDF) of the message delivery probability is derived and used to evaluate the performance with fragmentation. In addition, this CDF is used to improve the message delivery rate.
