Proceedings ArticleDOI
Steady and fair rate allocation for rechargeable sensors in perpetual sensor networks
TL;DR: This paper proposes a centralized algorithm and an asynchronous distributed algorithm that can compute the optimal lexicographically maximum data collection rate for each node, such that no node will ever run out of energy.
Journal ArticleDOI
Perpetual and fair data collection for environmental energy harvesting sensor networks
TL;DR: This paper seeks to compute the lexicographically maximum data collection rate and routing paths for each node such that no node will ever run out of energy, and proposes a centralized algorithm and two distributed algorithms.
Proceedings ArticleDOI
Trap Coverage: Allowing Coverage Holes of Bounded Diameter in Wireless Sensor Networks
TL;DR: This paper derives reliable, explicit estimates for the density needed to achieve trap coverage with a given diameter when sensors are deployed randomly, and shows by simulation that the analytical predictions of density are quite accurate even for small networks.
Proceedings ArticleDOI
Maximizing the Contact Opportunity for Vehicular Internet Access
TL;DR: This paper presents a new metric, called Contact Opportunity, as a characterization of a roadside WiFi network, and presents an efficient deployment method that maximizes the worst case contact opportunity under a budget constraint.
Proceedings ArticleDOI
Alpha Coverage: Bounding the Interconnection Gap for Vehicular Internet Access
TL;DR: A new notion of intermittent coverage for mobile users, called a-coverage, which provides worst-case guarantees on the interconnection gap while using significantly fewer APs than needed for full coverage is introduced.
