Computation hierarchy for in-network processing
by Ram Kumar, Vlasios Tsiatsis — 2003 — In WSNA ’03
…In this paper, we explore the network level architecture of distributed sensor systems that perform in-network processing. We propose a system with heterogeneous nodes that organizes into a hierarchal structure dictated by the computational capabilities. The presence of high-performance nodes amongs…

On Communication Security in Wireless Ad-Hoc Sensor Networks
by Sasha Slijepcevic, Miodrag Potkonjak, Vlasios Tsiatsis, Scott Zimbeck, Mani B. Srivastava — 2002 — In 11th IEEE Int. Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises
…Networks of wireless microsensors for monitoring physical environments have emerged as an important new application area for wireless technology. Key attributes of these new types of networked systems are the severely constrained computational and energy resources, and an ad hoc operational environm…

Optimizing Sensor Networks in the Energy-Latency-Density Design Space
by Curt Schurgers, Vlasios Tsiatsis, Student Member, Student Member, Saurabh Ganeriwal, Mani Srivastava, Senior Member — 2002 — IEEE Transactions on Mobile Computing
…In wireless sensor networks, energy efficiency is crucial to achieving satisfactory network lifetime. To reduce the energy consumption significantly, a node should turn off its radio most of the time, except when it has to participate in data forwarding. We propose a new technique, called Sparse T…

Estimating clock uncertainty for efficient duty-cycling in sensor networks
by Saurabh Ganeriwal, Deepak Ganesan, Hohyun Sim, Vlasios Tsiatsis, Mani B. Srivastava — 2005 — in Sensor Networks,” in Proc. of ACM SenSys
…Radio duty cycling has received significant attention in sensor networking literature, particularly in the form of protocols for medium access control and topology management. While many protocols have claimed to achieve significant duty-cycling benefits in theory and simulation, these benefits have…

Topology Management for Sensor Networks:
by Exploiting Latency And, Curt Schurgers, Vlasios Tsiatsis, Saurabh Ganeriwal, Mani Srivastava — 2002
…In wireless sensor networks, energy efficiency is crucial to achieve satisfactory network lifetime. In order to reduce the energy consumption of a node significantly, its radio needs to be turned off. Yet, some nodes have to participate in multi-hop packet forwarding. We tackle this issue by exploit…

STEM: Topology Management for Energy Efficient
by Curt Schurgers Vlasios, Curt Schurgers, Vlasios Tsiatsis, Mani B. Srivastava — 2002 — in IEEE Aerospace Conference
…In wireless sensor networks, where energy efficiency is the key design challenge, the energy consumption is typically dominated by the node's communication subsystem. It can only be reduced significantly by transitioning the embedded radio to a sleep state, at which point the node essentially retrac…
