Data collection and transmission are crucial tasks in current marine surveillance systems. Each node samples in a specific area and transmits its sensing data back to the land by satellites. In this paper, we propose a methodology of a vessel-based ocean monitoring delay tolerant networking (VOM-DTN) which is a cost saving DTN utilizing the existing vessels' daily working voyages to transmit ocean...
Most disruption-tolerant networking protocols focus on mere contact and intercontact characteristics to make forwarding decisions. We propose to relax such a simplistic approach and include multi-hop opportunities by annexing a node's vicinity to its network vision. We investigate how the vicinity of a node evolves through time and whether such knowledge is useful when routing data. By analyzing a...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
