Estimation of target position from multi-frame binary data provided by a wireless sensor network (WSN) can be done by optimizing a complex multimodal likelihood function. Deterministic quasi Newton-Raphson (QNR) schemes with line search are typically used for optimization in maximum likelihood estimation. However, these methods often find a local minimum,(More)
A Mobile Ad hoc Network (MANET) is a kind of wireless ad-hoc network, and is a self configuring network of mobile routers connected by wireless links. Self configurability and easy deployment feature of the MANET resulted in numerous applications in this modern era. Efficient routing protocols will make MANETs reliable. Various research communities are(More)
Available resources limit the performance and lifetime of a wireless sensor network. In order to increase network lifetime in the face of depleting resources, networks that can be reconfigured to meet specified performance criteria are of interest. For a target localization scenario using binary sensor data, we present an approach in which network(More)
— This paper proposes belief propagation based combined decoding scheme for low-density parity-check (LDPC)-coded orthogonal frequency-division multiplexing (OFDM) system with a peak-to-average power ratio (PAPR) reduction using the partial transmit sequence (PTS), which does not transmit PTS side information about the phase factors. I. INTRODUCTION It is(More)
The aim of present study was to evaluate effect of lyophilized extract of Tridax procumbens Linn. in rodent models of inflammatory and neuropathic pain. The antiallodynic and antihyperalgesic activity of Tridax procumbens was assessed in Chronic Constriction Injury of Sciatic Nerve in rats (CCI) and Scald pain model in rats (burning pain) respectively at(More)
This paper describes a localized performance-guided reconfiguration (PGR) algorithm for reconfiguring a distributed sensor network in a target localization scenario using binary sensor data. PGR works by activating redundant sensors available to replace failed sensors based on the improvement in target localization performance offered. Localized application(More)
