A two-tier data dissemination model for large-scale wireless sensor networks
TLDR
This paper describes TTDD, a Two-Tier Data Dissemination approach that provides scalable and efficient data delivery to multiple mobile sinks and evaluates TTDD performance through both analysis and extensive simulation experiments. Expand
Statistical en-route filtering of injected false data in sensor networks
TLDR
The results show that SEF can be implemented efficiently in sensor nodes as small as Mica2, and can drop up to 70% of bogus reports injected by a compromised node within five hops, and reduce energy consumption by 65% or more in many cases. Expand
PEAS: a robust energy conserving protocol for long-lived sensor networks
TLDR
A robust energy-conserving protocol that can build long-lived, resilient sensor networks using a very large number of small sensors with short battery lifetime, PEAS can extend a sensor network's functioning time in linear proportion to the deployed sensor population. Expand
TTDD: Two-Tier Data Dissemination in Large-Scale Wireless Sensor Networks
TLDR
TTDD is described, a Two-Tier Data Dissemination approach that provides scalable and efficient data delivery to multiple, mobile sinks that handles sink mobility effectively with performance comparable with that of stationary sinks. Expand
GRAdient Broadcast: A Robust Data Delivery Protocol for Large Scale Sensor Networks
TLDR
The analysis shows quantitatively the advantage of interleaved mesh over multiple parallel paths and shows that GRAB can successfully deliver over 90% of packets with relatively low energy cost, even under the adverse conditions of 30% node failures compounded with 15% link message losses. Expand
Security in mobile ad hoc networks: challenges and solutions
TLDR
The security issues related to this problem are identified, the challenges to security design are discussed, and the state-of-the-art security proposals that protect the MANET link- and network-layer operations of delivering packets over the multihop wireless channel are reviewed. Expand
Statistical en-route filtering of injected false data in sensor networks
TLDR
Analysis and simulations show that SEF is able to drop 80/spl sim/90% injected false reports by a compromised node within 10 forwarding hops, and reduce energy consumption by 50% or more in many cases. Expand
A scalable solution to minimum cost forwarding in large sensor networks
TLDR
This work presents a novel backoff-based cost field setup algorithm that finds the optimal costs of all nodes to the sink with one single message overhead at each node in a large sensor network. Expand
PEAS: a robust energy conserving protocol for long-lived sensor networks
TLDR
This paper presents the design of PEAS, a simple protocol that can build a long-lived sensor network and maintain robust operations using large quantities of economical, short- lived sensor nodes. Expand
Toward resilient security in wireless sensor networks
TLDR
This paper proposes a novel location-based approach in which the secret keys are bound to geographic locations, and each node stores a few keys based on its own location, thus limiting the damages caused by a collection of compromised nodes. Expand
