  2. Wireless Mesh Networks:a survey Bylan F. Akyildiz, Xudong Wang, Welin WangComputer Network, 2005 by Jeong - Ganghee Advanced Operating System – Spring 2012

  3. Advanced Operating System – Spring 2012 • A WMN is dynamically self-organized & self-configured. • The GW/bridge functionalities in mesh routers enable the integration of WMNs with various existing wireless networks. • Deploying a WMN is not too difficult. Introduction

  4. Advanced Operating System – Spring 2012 • WMNs consist of two types of nodes:mesh routers & mesh clients. • The architecture of WMNs can be classified into three main groups: • Infrastructure/Backbone • Client WMNs • Hybrid WMNs Network architecture

  5. Advanced Operating System – Spring 2012 • Infrastructure/Backbone Network architecture

  6. Advanced Operating System – Spring 2012 • Client WMNs • One type of radios on devices. • End-user applications Network architecture

  7. Advanced Operating System – Spring 2012 • Hybrid WMNs Network architecture

  8. Advanced Operating System – Spring 2012 • Multi-hop, Multi-link • Extend the coverage • To boost reliability. • Reducing the number of re-transmissions • Mobility dependence on the type of mesh nodes. Characteristic

  13. Advanced Operating System – Spring 2012 Network elements in imcs

  14. Advanced Operating System – Spring 2012 • VANET between ships • Ship2ship wireless communications. • IEEE 802.11s wireless mesh network. [WMN] • Considering high mobility of marine vessels, more stable and robust R.P. is preferred. • The ship location information • High-precision GPS receiver • Shipborne navigation instrument VANET between Ships

  15. Advanced Operating System – Spring 2012 • IEEE 802.11s mesh networkis compatible to those devices that are based on IEEE 802.11. • Wi-Fi interface (the dual-mode phone with both cellular & Wi-Fi interfaces, laptop computers with Wi-Fi interface) as Mesh Clients. • A high-precision GPS receiver terminal equipped with ECDIS* sends the navigation information to other ships through the Mesh network to make the navigation information available to the entire fleet. Mobile User Devices

  16. Advanced Operating System – Spring 2012 • Electronic Chart Display andInformation System • ECDIS provides continuous position and navigational safety information. • The system generates audible and/or visual alarms when the vessel is in proximity to navigational hazards. Mobile User Devices

  19. Advanced Operating System – Spring 2012 • Shipborne cellular gateway (C-GW) • Between VANET and the cellular mobile network. • Shipborne satellite gateway (S-GW) • Between VANET and the satellite mobile network. • needs to accomplish the conversions of the communication protocols & data formats. Shipborne Gateways

  20. Advanced Operating System – Spring 2012 Illustrative diagram of integrated maritime communication system Satellite Terminal - Figure 2.

  21. Advanced Operating System – Spring 2012 • Between VANET and the satellite MN. • For transferring data. • Inmarsat Fleet-Broadband*satellite terminal • To ensure sufficient link capacity. • Fleet-Broadband • Fleet-broadband is the first maritime communications service to provide cost-effective broadband data and voice, simultaneously, through a compact antenna on a global basis. Satellite Terminal

  22. Advanced Operating System – Spring 2012 • Using the latest generation Inmarsat satellite • Fleet-Broadband service can provide broadband voice & data services with data rate up to 432 kbps for the global maritime users. • The interface of voice comm.can beTelephone line (RJ11/45). • The data services can be supported by a variety of methods such as Ethernet, ISDN for connection with PC or PDAs. Satellite Terminal (cont.)

  23. Advanced Operating System – Spring 2012 • When aided by a Wi-Fi interface, • A satellite terminal can act as an 802.11s mesh client, and communicate directly with other Mesh Clients with Wi-Fi interface. • In addition, satellite terminal with streaming multimedia capability can support VoIP communications seamlessly across 802.11s Mesh network. Satellite Terminal (cont.)
