Abstract
Efficient and precise relief activities in disaster affected areas are required immediately after disasters. In order to deal with disaster situations, delay/disruption-tolerant network is a good way to deliver messages to destination by use of multihop forwarding by mobile nodes. Hence, a method called MRD [6], Message Relay Decision has been proposed to reduce the number of transmissions. However, it can not cope with the existence of obstacles and this will degrades message delivery rate. This paper proposes a new routing protocol, MRDAI (MRD with Area Increase) which increases message relay area to avoid negative effect of obstacle. The evaluation results confirm that the MRDAI achieves higher performance under the existence of obstacle.
