Crowdsourcing emergency data in non-operational cellular networks
(2017)
In overloaded or partially broken (i.e., non-operational) cellular networks, it is imperative to enable communication within the crowd to allow the management of emergency and crisis situations. To this end, a variety of ...
Distributed in-memory processing of All K Nearest Neighbor queries
(Institute of Electrical and Electronics Engineers Inc., 2016)
A wide spectrum of Internet-scale mobile applications, ranging from social networking, gaming and entertainment to emergency response and crisis management, all require efficient and scalable All k Nearest Neighbor (AkNN) ...
Minimum-hot-spot query trees for wireless sensor networks
(2010)
We propose a distributed algorithm to construct a balanced communication tree that serves in gathering data from the network nodes to a sink. Our algorithm constructs a near-optimally balanced communication tree with minimum ...
A local search mechanism for peer-to-peer networks
(2002)
One important problem in peer-to-peer (P2P) networks is searching and retrieving the correct information. However, existing searching mechanisms in pure peer-to-peer networks are inefficient due to the decentralized nature ...
Demo: Indoor geolocation on multi-sensor smartphones
(2013)
In this demo, we present an efficient hybrid indoor positioning solution that uses multi-sensory location-oriented observations, including WiFi, accelerometer, gyroscope and digital compass data, that are widely available ...
Towards planet-scale localization on smartphones with a partial radiomap
(2012)
The majority of smartphone localization systems use Assisted-GPS for fine-grained localization in outdoor spaces or WiFi-based RSS (Received Signal Strength) technologies for coarse-grain positioning in indoor and outdoor ...
FSort: External sorting on flash-based sensor devices
(2009)
In long-term deployments of Wireless Sensor Networks, it is often more efficient to store sensor readings locally at each device and transmit those readings to the user only when requested (i.e., in response to a user ...
In-network data acquisition and replication in mobile sensor networks
(2011)
This paper assumes a set of n mobile sensors that move in the Euclidean plane as a swarm. Our objectives are to explore a given geographic region by detecting and aggregating spatiooral events of interest and to store these ...
Optimized query routing trees for wireless sensor networks
(2011)
In order to process continuous queries over Wireless Sensor Networks (WSNs), sensors are typically organized in a Query Routing Tree (denoted as T) that provides each sensor with a path over which query results can be ...
pFusion: A P2P architecture for internet-scale content-based search and retrieval
(2007)
The emerging Peer-to-Peer (P2P) model has become a very powerful and attractive paradigm for developing Internet-scale systems for sharing resources, including files and documents. The distributed nature of these systems, ...
