Flooding and forwarding based on efficient routing protocol

Abstract

Delay tolerant network (DTN) is an approach that allows the transmission of data in a difficult situation where refined infrastructures are unavailable and the end-to-end path does not exist at the moment of transmission of data. The DTN efficiently improves network communications where the network connectivity is irregular or prone to disruptions. For transmission, DTN uses different kinds of routing protocols but still, they may lack some aspects such as buffer size, delivery rate, and number of message copy. In this paper, we represent an efficient routing protocol that is based on flooding and forwarding techniques along with the delivery predictability of nodes for transmission of messages. The main idea of the proposed model is to accelerate the dissemination of message in the early phase by employing spray and wait, and then to restrict dissemination in the later phase by using delivery predictability. We evaluated the performance of our protocol by simulation through the Opportunistic Network Environment (ONE) simulation tool. Obtained results show that ERP maintains a balance and offers a better way for the transmission of messages.
