Abstract
Wireless Delay Tolerant Networks (DTNs) are designed for intermittently connected wireless nodes to communicate with each other. In a DTN, messages are copied, stored and forwarded to other nodes when connection is established between nodes. Various routing protocols are designed to improve message delivery probability in networks but a very few of them consider energy constraint of nodes. In this paper we propose an Energy Aware Epidemic (EAEpidemic) routing protocol for DTNs. We extensively simulated our proposal and have shown that our proposed protocol performs better than the original Epidemic routing protocol in terms of energy consumption, message delivery probability and overhead ratio.
