Multi-hop Wireless Network Emulation on StarBED
نویسندگان
چکیده
In this paper, we present an architecture to emulate multihop wireless networks on StarBED, a wired-network testbed at Hokuriku Research Center of NICT, Japan. The architecture uses a distributed approach, and it can effectively emulate in real time the properties of WLAN contention-based media access mechanism.

A multi-hop PSO based localization algorithm for wireless sensor networks
A sensor network consists of a large number of sensor nodes that are distributed in a large geographic environment to collect data. Localization is one of the key issues in wireless sensor network researches because it is important to determine the location of an event. On the other side, finding the location of a wireless sensor node by the Global Positioning System (GPS) is not appropriate du...
متن کاملA Hidden Node Aware Network Allocation Vector Management System for Multi-hop Wireless Ad hoc Networks
Many performance evaluations for IEEE 802.11distributed coordination function (DCF) have been previouslyreported in the literature. Some of them have clearly indicatedthat 802.11 MAC protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. Although RTS/CTS transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...
متن کاملWLAN Emulation on StarBED
In this paper we present the Wireless LAN (WLAN) emulator that we design to run on StarBED, the large scale network experiment environment of the Hokuriku Research Centre in Ishikawa, Japan. As WLANs start to spread on an ever wider scale, the need to investigate application deployment on WLANs has become stringent. We develop an emulation environment since it allows using in experiments the re...
متن کاملAn emulation infrastructure for multi-hop wireless communication networks
In this paper, a novel approach for wireless network emulation is proposed. The emulation infrastructure is built on a virtualized Linux kernel (User Mode Linux) which allows for highly realistic emulations. The virtualized kernel is extended with software based wireless cards which are plugged in a generic physical layer emulator. The emulator proposed in this paper tries to reduce the gap bet...
متن کاملThe Feedback Based Mechanism for Video Streaming Over Multipath Ad Hoc Networks
Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...
