Fitzek b a b s t r a c tThis paper investigates the problem of efficient data dissemination in Mobile Ad hoc NETwork(MANETs). A testbed is presented; which provides a realistic degree of mobility inexperiments. The testbed consists of ten autonomous robots with mobile phones mountedon them. The mobile phones form an IEEE 802.11g ad hoc netw ...دانلود مقاله Performance Evaluation of Network Coding in IEEE 802.11 Wireless Ad Hoc Networks - انتشار 2014
Ad Hoc Networks Volume 16, May 2014, Pages 131–141 Kyu-Hwan Lee, Sunghyun Cho, Jae-Hyun Kim AbstractWe evaluate the practical network coding (NC) gain in a wireless ad hoc networks.First, we introduce how network coding can be applied to IEEE 802.11ad hoc networks. Next, we find obstructive factors by which the NC gainmay decrease as compared with the theoretical NC gain. Finally, throughthe performance evaluation, we analyze why a performance difference occursbetween practical and ...دانلود مقاله Error Correction Codes in Wireless Sensor Network: An Energy Aware approach انتشار 2010

World Academy of Science, Engineering and TechnologyVol:4 2010-01-26 Mohammad Rakibul Islam Abstract—Link reliability and transmitted power are two importantdesign constraints in wireless network design. Error control coding(ECC) is a classic approach used to increase link reliability andto lower the required transmitted power. It provides coding gain,resulting in transmitter energy savings at the cost of added decoderpower consumption. But the choice of ECC is very critical in thec ...دانلود مقاله Network Information Flow
IEEE TRANSACTIONS ON INFORMATION THEORY, VOL. 46, NO. 4, JULY 2000 Rudolf Ahlswede, Ning Cai, Shuo-Yen Robert Li, Senior Member, IEEE, andRaymond W. Yeung, Senior Member, IEEE Abstract—We introduce a new class of problems called networkinformation flow which is inspired by computer network applications.Consider a point-to-point communication network on whicha number of information sources are to be mulitcast to certain setsof destinations. We assume that the information sources are mutuall ...دانلود مقاله A multipath routing protocol for wireless sensor network for mine security monitoring - انتشار 2010
Mining Science and Technology (China) Volume 20, Issue 1, January 2010, Pages 148–151 XIAO Shuo1,2,*, WEI Xueye2, WANG Yu2 Abstract: Underground mining is a hazardous industrial activity. In order to provide a safe working environment for miners, aWireless Sensor Network (WSN) technology has been used for security monitoring. It can provide a wide range of surveillancewith a relatively low cost. In this study, an Energy-Based Multipath Routing (EBMR) protocol is proposed, wh ...رایانش ابری در شبکه های اجتماعی- social network - شامل 41 صفحه فایل ورد
