Abstract In this paper, we use the Opportunistic Network Environment environment to simulate a data collection application using a Delay Tolerant Network (DTN). A group of sensor nodes sense data from the environment and send these data to a destination node that collects them for statistical and data analysis purposes. Pedestrians and cyclist equipped with smart devices moving in Tirana city roads, will relay the sensed data via opportunistic contacts. Different simulations are done to identify among five routing protocols the most suitable for our DTN application. Keywords Delay Tolerant Networks · Simulation · Energy consumption
1 Introduction Nowdays a very big number of mobile nodes such as personal devices, smart-phones and tablets are used for communication and computing purposes. These mobile devices can form a Mobile Ad-hoc Network. In scenarios where the mobility of nodes and their distance is very high, network partitioning and islands can be created and end to end connectivity is very difficult to be maintained. To solve these problems, Delay Tolerant Networks (DTNs) can be used. DTNs are occasionally connected networks, characterized by the absence of a continuous path between the source and destination (Fall 2003). DTNs enable communication in sparse areas where end-to-end connectivity does not exists by using store-carry-and-forward approach. In a DTN, a node stores the message that it wants to send and carry it until it encounters another node and forwards a copy of the message. The node that received the message will do the same thing until the destination node is encountered or the message time to live (TTL) is expired. This process is called message switching. Waiting for a link to establish may take a long time and this will cause delay and effect also to the asymmetric data rate. * Evjola Spaho [email protected] 1

DTNs are first designed for the Interplanetary communication where opportunistic contacts and store-carry-andforward approach are used. However DTN communication architectures can be used also in applications for remote regions and developing areas (Demmer and Fall 2007; Pentland et al. 2004; Guo et al. 2011). Different copies of the same message will be routed independently in the network. This approach will improve the data delivery and reduce the average delay. The drawback of this approach is waste of network bandwidth and nodes storage. There are different research works with focus on routing in DTNs. In Demmer and Fall (2007), Uchida et al.
