abstract="Routing a message in networks that are dynamic in nature with time varying partially connected topology has been a challenge. The heterogeneity of the types of contacts available in such a network also adds to complexity. In this paper we present an approach to transfer messages in disruption/delay tolerant network when there is only intermittent connectivity between the nodes. Most of the existing approaches exploit either the opportunistic contacts and transfer messages using the probabilities of delivering a message or use periodic contacts. In addition to opportunistic contacts, we also have scheduled carriers that are available periodically. Scheduled carriers guarantee delivery of the messages to the base station, however, it may have an added delay. If a message can tolerate the delay through the scheduled carrier, it waits else it may be forwarded to an opportunistic contact. We define a utility function for a node to decide whether to forward the message to an opportunistic contact or to a scheduled contact.",
