—The widespread availability of mobile wireless devices offers growing opportunities for the formation of temporary networks with only intermittent connectivity. These intermittently-connected networks (ICNs) typically lack stable end-to-end paths. In order to improve the delivery rates of the networks, new store-carry-and-forward protocols have been(More)
Embedded sensors in mobile devices such as cars and smart phones present new opportunities to collect location-specific data about an environment. This data can be used to enable new real-time location-based applications. A major challenge is efficiently collecting, storing and sharing the data. This paper proposes Locus, a location-based data overlay for(More)
Many wireless sensor network protocols are employing gossip-based message dissemination, where nodes probabilistically forward messages, to reduce message overhead. We are concerned with emerging systems in stationary sensor networks that are multiple-source with each message targeted at every recipient, such as query and code propagation. Default(More)
A global-scale low cost outdoor Internet access infrastructure is finally attainable. Emerging projects are leveraging the proliferation of private Wi-Fi networks to build a global-scale ubiquitous access infrastructure from autonomous, independently owned Internet connections at homes and other private properties. To ensure the trace ability and(More)
—Protocols for opportunistic networks have until this point focused primarily on overcoming the partitioning of those networks. However, emerging studies show that opportunistic networks also exhibit considerable clustering. Neither current store-carry-forward protocols nor path-based protocols are equipped to effectively handle both of these network(More)
A new model for developing cellular-like networks is emerging in the market in which end users own and install part of the infrastructure and share it with other customers. The network grows "organically" as more end users join and contribute to its expansion. To drastically reduce the cost of these customer-installed networks, self-managed service designs(More)
