SwanMesh: A Multicast Enabled Dual-Radio Wireless Mesh Network for Emergency and Disaster Recovery Services

Abstract

<p class="MsoNormal" style="text-align: left; margin: 0cm 0cm 0pt; layout-grid-mode: char;" align="left"><span class="text"><span style="font-family: ";Verdana";,";sans-serif";; mso-bidi-font-family: Arial;"><span style="font-size: x-small;">In this paper we present the design and implementation of our multicast enabled dual-radio wireless mesh network for emergency communications. We have developed a novel implementation of a Multicast extension to the AODV (MAODV) protocol in Linux Kernel 2.6 user space to support multicast operation of our SwanMesh testbed. This paper presents the architecture of our SwanMesh testbed. Furthermore, we present unicast communication throughput test results. We observed that SwanMesh can efficiently deliver data services such as broadband internet in emergency situations using its unicast functionality although there were noticeable throughput drops after each hop. Therefore the SwanMesh multicast operation may be suitable for delivery of real time applications in emergency communication, such as audio and video teleconferencing. We also performed validation tests to ensure correct multicast functionality of our MAODV implementation. The possible application of WMN in emergency is discussed.</span></span></span><span style="mso-bidi-font-family: Arial;"></span></p&gt

Power management in solar-powered long range WiFi test-bed

“…drop-and-play, which is of particular importance in emergency response situations. An example of such networks is SwanMesh, as a wireless mesh network for emergency and disaster recovery services [9]. As a research project, SwanMesh is enabling both unicast and multicast emergency communication.…”

A handheld mobile device for wireless mesh networks in healthcare

“…To implement multicast operation in our SwanMesh we have designed and implemented a new multicast extension to popular AODV, named Swan-MAODV here, routing protocol in latest Linux Kernel 2.6 user space [4]. To use multicast operation of ARM architecture based handheld mobile devices in healthcare, we cross compiled and implemented our Swan-MAODV on these mobile devices.…”

“…Previous research has seen the successful development of a wireless mesh networking infrastructure for healthcare data transmissions [4][5]. In this paper, we take one step further to develop a mobile device which can act as a mesh node which joins and leaves the network automatically.…”

Urban Delay-Tolerant Multicast Using Uncontrolled Mobile Relay

“…This opportunistic multicast routing can be implemented in delay-tolerant applications which do not require instant network communication and when full network coverage is physically not feasible or economically unjustified [4]. This type of communication is of particular significance in post-disaster scenarios, when stationary fixed well-connected wireless networks are unavailable and emergency alerts need to be disseminated to designated devices or interested users [5][6][7]. They can also be used, e.g., to update the settings of large groups of nodes in remote locations with identical configurations [8].…”
