To support seamless communications for roaming users over heterogeneous wireless networks, mobile ad-hoc networks (MANETs) are receiving a special interest in the research community due to its infrastructure-less nature. MANETs can help to achieve a seamless service for users roaming over areas with no coverage from other wireless networks. As a result, MANETs are a key access network component of...
We study a mobile wireless network where groups or clusters of nodes are intermittently connected via mobile "carriers'' (the carriers provide connectivity over time among different clusters of nodes). Over such networks (an instantiation of a delay tolerant network), it is well-known that traditional routing algorithms perform very poorly. In this paper, we propose a two-level Back- Pressure...
Internet Relay Chat (IRC) is a critical application in military networks for maintaining situational awareness and conducting battle management at all echelons. But these networks are often subject to frequent disconnections, limited bandwidth, and long delays, especially when using satellite services and field radios. Such conditions are inhospitable to TCP, and thus the standard IRC protocol, which...
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...
