ALOHA-Like Neighbor Discovery in Low-Duty-Cycle Wireless Sensor Networks

by unknown authors
"... Abstract—Neighbor discovery is an essential step for the self-organization of wireless sensor networks. Many algorithms have been proposed for efficient neighbor discovery. However, most of those algorithms need nodes to keep active during the process of neighbor discovery, which might be difficult ..."

1 Understanding the Flooding in Low-Duty-Cycle Wireless Sensor Networks

by Zhenjiang Li, Mo Li, Junliang Liu, Shaojie Tang
"... Abstract—In low-duty-cycle networks, sensors stay dormant most of time to save their energy and wake up based on their needs. Such a technique, while prolonging the network lifetime, sets excessive challenges for efficient flooding within the network. Tailored for obtaining short delay in low-duty-c ..."

ASYMPTOTIC CONNECTIVITY OF LOW DUTY-CYCLED WIRELESS SENSOR NETWORKS

by unknown authors
"... In this paper we study the asymptotic connectivity of a low duty-cycled wireless sensor network, where all sensors are randomly duty-cycled such that they are on/active at any time with a fixed probability. A wireless network is often said to be asymptotically connected if there exists a path from e ..."

L²: Lazy Forwarding in Low Duty Cycle Wireless Sensor Networks

by Zhichao Cao, Yuan He, Yunhao Liu
"... Energy-constrained wireless sensor networks are duty-cycled, relaying on multi-hop forwarding to collect data packets. A forwarding scheme generally involves three design elements: media access, link estimation, and routing strategy. Most existing studies, however, focus only on a subset of those t ..."
