Abstract

In DTN networks the existence of a simultaneous path between a source and a destination is not assumed. This type of networks completely breaks the main assumptions on which MANET routing protocols are built. Routing in DTN networks is usually based on some form of controlled flooding. But often this results in very high resource consumption and network congestion. In this paper we propose a fuzzy-based routing protocol for DTN networks, called Adaptive Priority Routing Protocol (APRP). It uses three local parameters (forward transmission count, buffer size and remaining life time) from each message as inputs to fuzzy system to prioritize which message is to be transmitted next from the buffer. There is no need to know a priori information about network. Simulation results are used to draw conclusions regarding to the proposed routing algorithm and compared it with well known routing protocols: Epidemic, PRoPHET, Spray and Wait routing protocols. Conducted experiments showed that our proposed algorithm exhibits superior performance with respect to the well known routing protocols in terms overall average hop count, delivery of messages, average message delay and average buffer occupancy time.
