INSTITUTE “ Synchronization in Low Duty Cycle UWB Systems Using Iterative
Iterative message passing algorithms (MPAs) on graphs, which are generalized from the well-known turbo decoding algorithm, have been studied intensively in recent years because they can provide near optimal performance and significant complexity reduction. The goal of the first part of this work is to apply message passing techniques to the pseudo random code acquisition problems. To do that, g...
متن کاملClocks , Power and Synchronization in Duty - Cycled Wireless Sensor Nodes
Recent advances in CMOS VLSI ICs and micro-electromechanical technology have led to development of small, low-cost, and low-power multifunctional sensors. Wireless sensor networks (WSNs) are large-scale networks of such sensors, dedicated to observing and monitoring various aspects of the physical world. Some intrinsic properties of WSNs including limited resource of energy, storage, computatio...
متن کاملfault location in power distribution networks using matching algorithm
چکیده رساله/پایان نامه : تاکنون روشهای متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روشها در شبکه توزیع به دلایلی همچون وجود انشعابهای متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تکفاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...
Power Saving in Wireless Ad hoc Networks Without Synchronization
Power saving strategies generally attempt to maximize the time that nodes spend in a low power consumption sleep state. Such strategies often require the sender to notify the receiver about pending traffic using some form of traffic announcement. Although asynchronous traffic announcement mechanisms are particularly suitable for the ad hoc environment, they also provide relatively limited power...
متن کاملPoster Abstract: Duty-Cycle Distribution in Low-Power Collection
We characterize the interplay between collection and lowpower operation by studying the joint impact of the offered load and the Low Power Listening sleep time setting on the duty-cycle distribution in a large-scale sensor network testbed. Collection services must be able to work on top of a low-power MAC. The Collection Tree Protocol (CTP) [1] has been shown to perform very well on top of Box-...
