Energy-constrained modulation optimization
- IEEE Transactions on Wireless Communications
, 2005
"... Abstract — We consider wireless systems where the nodes operate on batteries so that energy consumption must be minimized while satisfying given throughput and delay requirements. In this context, we analyze the best modulation strategy to minimize the total energy consumption required to send a giv ..."

Energy-Constrained Applications
, 2006
"... Existing sensor network architectures are based on the assumption that data will be polled. Therefore, they are not adequate for long-term battery-powered use in applications that must sense or react to events that occur at unpredictable times. In response, and motivated by a structural autonomous c ..."

crack monitoring (ACM) application from civil engineering that requires bursts of high resolution sampling in response to aperiodic vibrations in buildings and bridges, we have designed, implemented, and evaluated lucid dreaming, a hardware/software technique to dramatically decrease sensor node power
Adaptive Protocols for Information Dissemination in Wireless Sensor Networks
, 1999
"... In this paper, we present a family of adaptive protocols, called SPIN (Sensor Protocols for Information via Negotiation) , that eciently disseminates information among sensors in an energy-constrained wireless sensor network. Nodes running a SPIN communication protocol name their data using high-lev ..."

Protocols for self-organization of a wireless sensor network
- IEEE Personal Communications
, 2000
"... We present a suite of algorithms for self-organization of wireless sensor networks, in which there is a scalably large number of mainly static nodes with highly constrained energy resources. The protocols further support slow mobility by a subset of the nodes, energy-efficient routing, and formation ..."

Distributed optimization in an energy-constrained network
- in Proceedings of the IEEE International Conference on Acoustics, Speech and Signal Processing
"... We consider a distributed optimization problem where n nodes, Sl, l ∈ {1,..., n}, wish to minimize a common strongly convex func-tion f(x), x = [x1,..., xn]T, and suppose that node Sl only has control of variable xl. The nodes locally update their respective vari-ables and periodically exchange thei ..."

required for nodes to obtain an -minimizer of f(x) in the mean square sense. In an earlier work, we considered analog communication schemes and proved that the communication energy must grow at the rate of Ω(−1) to obtain an -minimizer of a convex quadratic function. In this paper, we consider digital
Upper Bounds on the Lifetime of Sensor Networks
, 2001
"... In this paper, we ask a fundamental question concerning the limits of energy e#ciency of sensor networks - What is the upper bound on the lifetime of a sensor network that collects data from a specified region using a certain number of energy-constrained nodes? The answer to this question is valuabl ..."
