Service discovery is an essential step in deploying many wireless network applications. The design of service discovery protocols is particularly challenging for mobile wireless networks because of their dynamic and unstructured nature. Most of the previously proposed protocols are based on the assumption that there exists an end-to-end connection from the query source node to the destination node,...
Routing in delay tolerant networks (DTNs) in which most of the nodes are mobile and intermittently connected is a challenging problem because of unpredictable node movements and lack of knowledge of future node connections. To ensure reliability against failures and increase the success rate of delivery, erasure coding technique is used to route messages in DTNs. In this paper, we study how the cost...
Intermittently connected mobile networks, also called delay tolerant networks (DTNs), are wireless networks in which at any given time instance, the probability of having a complete path from a source to destination is low. Several routing algorithms have been proposed for such networks based on control flooding in which there is a fixed number of copies for each message. Although a DTN is delay tolerant...
