A message ferrying approach for data delivery in sparse mobile ad hoc networks

摘要: Mobile Ad Hoc Networks (MANETs) provide rapidly deployable and self-configuring network capacity required in many critical applications, e.g., battlefields, disaster relief wide area sensing. In this paper we study the problem of efficient data delivery sparse MANETs where partitions can last for a significant period. Previous approaches rely on use either long range communication which leads to rapid draining nodes' limited batteries, or existing node mobility results low rates large delays. paper, describe Message Ferrying (MF) approach address problem. MF is mobility-assisted utilizes set special mobile nodes called message ferries (or short) service deployment area. The main idea behind introduce non-randomness movement exploit such help deliver data. We two variations MF, depending whether initiate proactive movement. design exploits improve performance reduce energy consumption nodes. evaluate via extensive ns simulations confirm both under variety conditions.
