Towards Designing a Routing Protocol for Opportunistic Networks
Abstract
Intermittently connected opportunistic networks experience frequent disconnections and shorter contact durations. Therefore routing of messages towards their destinations needs to be handled from various points of view. Predictability and connectedness are two features which can be determined by participating mobile nodes of an opportunistic content distribution network using their past contacts. Epidemic or probabilistic routing protocols such as PRoPHET do not fully utilize these features to route messages towards their destinations. In this paper we describe the design, implementation, experiment set up and the performance validation of a new, adaptive routing protocol which utilizes the predictability and connectedness features to route messages efficiently. Simulation based comparative studies show that the proposed routing protocol outperforms existing Epidemic and Probabilistic routing protocols in delivering messages.
