Abstract This study proposes Delay/Disruption Tolerant Networking (DTN) routing strategies
for disaster information delivery under the existence of obstacles that are based on the …

In the past decade, unmanned aerial vehicles (UAVs) have become a major research topic
in robotics, despite their existence since 1915. UAVs can perform various activities efficiently …

Reliable and timely delivery of data to mobile targets is a challenging problem in mobile ad-
hoc networks, because of the opportunistic and unpredictable nature of the problem. Finding …

In opportunistic network with node clusters, it is usually necessary to set up ferry nodes to
connect each cluster to achieve the overall connectivity of the network, and the movement …

Routing in delay-tolerant networks exploits node mobility to distribute messages among inter-
contact of mobile nodes in intermittently connected environments. However, only depending …

Efficient and precise relief activities in disaster affected areas are required immediately after
disasters. In order to deal with disaster situations, delay/disruption-tolerant network is a good …

By introducing the state of the art sensing technologies to the home, monitoring the daily
activities of elders living alone or with husband/wife only, will be common soon to support …

At the beginning of the thesis, this chapter introduces the research about delay tolerant
networks (DTNs) and unmanned aerial vehicles (UAVs). The framework of this chapter is …
