Effective buffer management and scheduling of bundles in delay tolerant networks with finite buffers
摘要：
Delay tolerant networks (DTNs) are a class of emerging networks that experience frequent and long-duration partitions. These networks have a variety of applications in situations such as crisis environments and deep-space communication. In this paper, the problem of routing in DTNs is studied. While routing in the Internet and mobile ad hoc networks has been studied extensively, due to the unique characteristic of frequent partitioning in DTNs, traditional ad hoc routing protocols such as AODV a 阅读全文
