A Survey of Buffer Management Strategies in Delay Tolerant Networks

When configuring a delay tolerant network (DTN), there are many aspects that need to be taken into consideration for an effective and efficient network. One aspect is a buffer management strategy. Buffer strategies are used to determine which packets need to be forwarded or dropped. This paper will focus on the variety of buffer management strategies available, providing a comprehensive survey and analysis. They have all been taken into consideration, evaluated, and then classified into different categories based on their features.
