A message ferrying approach for data delivery in sparse mobile ad hoc networks
TL;DR: This paper describes a mobility-assisted approach which utilizes a set of special mobile nodes called message ferries to provide communication service for nodes in the deployment area and evaluates the performance of MF via extensive ns simulations which confirm it is efficient in both data delivery and energy consumption under a variety of network conditions.
Proceedings ArticleDOI
Controlling the mobility of multiple data transport ferries in a delay-tolerant network
TL;DR: This paper considers the message ferrying (MF) scheme which exploits controlled mobility to transport data in delay-tolerant networks, where end-to-end paths may not exist between nodes, and examines the use of multiple ferries in such networks.
Proceedings ArticleDOI
Message ferrying: proactive routing in highly-partitioned wireless ad hoc networks
Wenrui Zhao,Mostafa H. Ammar +1 more
TL;DR: The basic design of the Message Ferrying or MF scheme is proposed and a general framework to classify variations of MF systems is developed and studied to study ferry route design problem in stationary node case which is shown to be NP-hard and provide an efficient algorithm to compute ferry route.
Proceedings ArticleDOI
Capacity Enhancement using Throwboxes in DTNs
TL;DR: This work proposes algorithms to deploy stationary throwboxes in the network that simultaneously consider routing as well as placement, and presents placement algorithms that use more limited knowledge about the network structure.
Proceedings ArticleDOI
Multicasting in delay tolerant networks: semantic models and routing algorithms
TL;DR: New semantic models for DTN multicast are proposed and several multicast routing algorithms with different routing strategies are developed, and a framework to evaluate these algorithms in DTNs is presented.
