Delay tolerant networks (DTNs) are a special type of wireless mobile networks which may lack continuous network connectivity. Multicast is an important routing function that supports the distribution of data to a group of users, a service needed for many potential DTNs applications. While multicasting in the Internet and mobile ad hoc networks has been studied extensively, efficient multicasting in...
The core functionality of a wireless sensor network (WSN) is to detect deviations in expected normal behavior and report it to the sink. In this paper, we propose TRACK - a novel sink mobility model exploiting the connected dominating set (CDS) property of a network graph. TRACK, to the best of our knowledge, is the first contemporary sink mobility model to exploit the CDS property for WSN lifetime...
Geometric routing in mobile ad-hoc networks (MANETs) is comprised of two forwarding modes: greedy forwarding and face forwarding. It is known that face forwarding is inefficient and fails frequently in practical situations. A previous work, NEAR [2], avoids switching to face forwarding by predicting local minima and not forwarding messages to them. However, NEAR predicts excessive local minima, which...
We propose to use node mobility to enhance routing capability in a mobile network. A dual-control planes model is presented, which includes the traditional S(stationary)-plane for message routing among stationary nodes using connection-based message routing. In addition, we introduce a new control plane, M(mobile)-plane, for trajectory control of mobile nodes. A message routing consists of a sequence...
