SPINS: Security Protocols for Sensor Networks

by Adrian Perrig, Robert Szewczyk, Victor Wen, David Culler, J. D. Tygar , 2001
"... As sensor networks edge closer towards wide-spread deployment, security issues become a central concern. So far, the main research focus has been on making sensor networks feasible and useful, and less emphasis was placed on security. We design a suite of security building blocks that are optimized ..."

Energy-Efficient, Collision-Free Medium Access Control for Wireless Sensor Networks

by Venkatesh Rajendran, Katia Obraczka, J.J. Garcia-Luna-Aceves , 2003
"... The traffic-adaptive medium access protocol (TRAMA) is introduced for energy-efficient collision-free channel access in wireless sensor networks. TRAMA reduces energy consumption by ensuring that unicast and broadcast transmissions incur no collisions, and by allowing nodes to assume a low-power, ..."

Negotiation-based Protocols for Disseminating Information in Wireless Sensor Networks

by Joanna Kulik, Wendi Heinzelman - Wireless Networks , 2002
"... Abstract. In this paper, we present a family of adaptive protocols, called SPIN (Sensor Protocols for Information via Negotiation), that efficiently disseminate information among sensors in an energy-constrained wireless sensor network. Nodes running a SPIN communication protocol name their data usi ..."

Benchmarking for Wireless Sensor Networks

by Jono Vanhie-van Gerwen, Stefan Bouckaert, Ingrid Moerman, Piet Demeester
"... (WSN) protocols steadily increases, the evaluation methods have largely remained the same. Although experimentally-supported research is gaining popularity, protocol evalua-tion and comparison remains difficult due to a lack of performance analysis methodologies. This work introduces a wireless-benc ..."

DRUG: An Energy-Efficient Data-Centric Routing Protocol for Wireless Sensor Networks

by B. P. S. Sahoo, Deepak Puthal
"... Abstract—In general, sensor nodes are deployed in left unat-tended area. In such situation feeding energy to the batteries or replacing the batteries is difficult or even sometimes impossible too. Therefore, prolonging the network lifetime is an important optimization goal in this aspect. In this pa ..."
Abstract - Add to MetaCart
. In this paper, we propose a new Energy-efficient Datacentric RoUtinG protocol called DRUG. In this paper, we propose an adaptive Data centric approach to find an optimal routing path from source to sink when the sensor nodes are deployed randomly deployed in a restricted service area with single sink.

Duty-Cycle-Aware Broadcast in Wireless Sensor Networks

by Feng Wang, Jiangchuan Liu
"... Abstract—Broadcast is one of the most fundamental services in wireless sensor networks (WSNs). It facilitates sensor nodes to propagate messages across the whole network, serving a wide range of higher-level operations and thus being critical to the overall network design. A distinct feature of WSNs ..."

Unified Broadcast in Sensor Networks

by Morten Tranberg Hansen, Raja Jurdak, Branislav Kusy - In IPSN ’11: Proceedings of the 10th International Conference on Information Processing in Sensor Networks , 2011
"... Complex sensor network applications include multiple servicessuchascollection, dissemination, timesynchronization, and failure detection protocols. Many of these protocols require local state maintenance through periodic broadcasts which leads to high control overhead. Recent attempts to consolidate ..."
