Abstract
Delay-Tolerant Networks are wireless networks with no existing infrastructure, where disconnections between nodes may occur frequently due to node mobility and power outages. In order to achieve data delivery, store-and-forward protocols are used in DTN. Thus routing protocols based on epidemic message dissemination has been proposed, such as Epidemic routing. Thus the nodes in such networks are required more buffer space to carry the data until the communication opportunity arrives. When the buffer gets full it needs to discard some of the messages from it based upon the drop policies implemented. As the nodes are mobile, mobility models play an important role to measure the performance of any protocol. In this paper the performance of Epidemic Router is analyzed with different drop policies by varying the mobility models through the simulation.
