Abstract
In this paper, we evaluate the energy consumption of different routing protocols in a Delay Tolerant Network (DTN). Seven groups with three stationary sensor nodes for each group sense the temperature, humidity and wind speed and send these data to a stationary destination node that collects them for statistical and data analysis purposes. The opportunistic contacts will exchange the sensed data to different relay nodes that are pedestrians and cyclist equipped with smart devices moving in Tirana city roads, until the destination node is reached. For simulations we use the Opportunistic Network Environment (ONE) simulator. Nodes in this DTN are energy constrained and play an important role in the success of delivering messages. When the energy of a node is low chance to deliver messages across the network. In this work, we evaluate and compare the performance of different routing protocols in order to find the energy-efficient routing protocol to be used for message transmission for our DTN application. We evaluate the nodes average remaining energy, the number of dead nodes, delivery probability and overhead ratio for different routing protocols.
