A robust proactive routing protocol for intermittently connected opportunistic networks

Intermittently connected opportunistic networks experience frequent disconnections and shorter contact durations. Therefore routing of packets towards their destinations needs to be handled from various points of view. Predictability and connectedness are two information that mobile nodes, which participate in an opportunistic content distribution, determine using their past contacts. Epidemic or probabilistic protocols do not fully utilize these information to route packets towards their destinations. In this paper we present our experimental design, implementation and the performance evaluation of a new, robust routing protocol which utilizes the predictability and connectedness properties to maintain efficient routing information. Simulation based comparative studies show that the proposed routing protocol outperforms existing Epidemic and probabilistic protocols in delivering packets.
