Lei Zhang: Underwater Acoustic Sensor Networks Protocol Design

Underwater Acoustic Sensor Networks Protocol Design


The limited bandwidth and power resources as well as the 3-D topology in underwater acoustic sensor networks have made the geographic routing a favorite choice. While most of the detour strategies in the existing geographic routing do not work well for underwater sensor networks, the spanning tree routing detour strategy can efficiently find a detour for a packet when greedy forwarding fails. In this research, we propose novel spanning trees, namely Traffic-Aware Routing Tree (TART) and Energy-Aware Routing Tree (EART), which are constructed completely in a bottom-up fashion with the traffic load and residual energy level in mind.Simulation results show that those spanning trees have very few conflicting hulls, result in much higher path throughput and residual energy level when compared against other spanning trees, leading to a better routing performance in a 3-D underwater acoustic sensor network.

Since its debut in 1990, Robert Jordan's Wheel of Time series has captivated millions of readers around the world. Over the course of fifteen books and millions of words, Jordan created a rich and detailed world. Yet only a fraction of Jordan's imaginings ended up on the page, with the rest going into his personal files. The Wheel of Time Companion finally reveals a wealth of previously-unreleased information about the world of the Wheel of Time, as well as expanding on many known details. It is unmissable reading for fans of this bestselling series. French Underwater Acoustic Sensor Networks Protocol Design free epub mathematician and philosopher. Kids will love this funny and very An Afghan woman's life expectancy is just 44 years, and her life cycle often begins and ends in disappointment: being born a girl and finally, having a daughter of her own. For some, disguising themselves as boys is the only way to get ahead. Nordberg follows women such as Azita Rafaat, a parliamentarian who once lived as a Bacha Posh, the mother of seven-year-old Mehran, who she is raising as a Bacha Posh as well, but for different reasons than in the past. There's Zahra, a teenage student living as a boy who is about to display signs of womanhood as she enters puberty. And Skukria, a hospital nurse who remained in a Bacha Posh disguise until she was twenty, and who now has three children of her own. Exploring the historical roots of this tradition, The Underground Girls of Kabul is a fascinating and moving investigation.
