IP and Ad Hoc Networking

A 3-Day Short Course

IP protocols form the basis for networking multimedia applications across local, metropolitan, and wide-area networks as well as over the Internet. The use of mobile computers is growing at a phenomenal rate. Cellular wireless service providers and equipment manufacturers have been expanding their systems to provide multimedia packet switching services. The telecommunications revolution involves extensive use of IP-based mobile wireless access for the transport of data flows and multimedia streams. Infrastructure-based solutions provide users wireless access to base stations or to access points that provide connection to the Internet and other networks, while ad hoc mobile wireless nets are established to support communications when no fixed backbone network is available. Wireless networking implementations based on 802.11 MAC and physical layer standards are widespread. Such wireless local area networks will be interconnected through the autonomous synthesis of backbone mesh networks, including the use of WiMax/LTE based networked mesh systems.

Complete Details

The availability of cheap, low-power, and miniature embedded processors, radios, sensors, and actuators—often integrated on a single chip—is leading to the development of wireless sensor networks. Such systems use wireless communications and computing for interacting with the physical world in applications such as security and surveillance, smart classroom, monitoring of natural habitats and eco-systems, and medical monitoring. New developments in the architecture, management, and control of high-capacity survivable mobile ad hoc wireless networks that autonomously self-configure to enhance the effectiveness of sensor-oriented detection and tracking processes are of critical importance to the construction of next-generation military networks that enable the effective operation of unmanned-vehicle-aided network-centric combat C4ISR systems, as well as the operation of disaster-relief and security systems.

This course describes the existing and newly evolving networking fundamentals of TCP/IP-based protocols and related algorithms used for efficiently transporting traffic among stationary and mobile end users across wireline and wireless media. Integrating communications, switching, networking, traffic, service, computer engineering, and management principles, the course provides participants with the fundamentals of Internet-Protocol (IP)-based computer communications networks and their technologies, architectures, planning, management, evaluation, and design. Elements essential to the implementation and control of cost-effective, reliable, and responsive IP computer communication networks and the evolving integrated wireline/wireless and UAV-aided Internets (“Internet in the sky”) are thoroughly discussed. Approaches and techniques for efficient activation of energy resource limited sensor outfitted platforms and for networking the data messages and streams produced by such entities are also presented.

The course is self-contained and basic networking principles are explained simply without assuming prior networking experience or mathematical background. The course is divided into two parts. Part I presents the fundamentals of IP networking. In this three-day second part, advanced IP networking methods and networking techniques and protocols for mobile ad hoc wireless networks, including sensor networks, are systematically described and evaluated.

This course is designed for communications, computer, telecommunications, and system engineers; network managers; administrators; programmers; system analysts; project leaders; and scientists seeking to understand:

  • Principles of TCP/IP-based communications networking, control, and management
  • Up-to-date performance evaluations and design considerations for IP communications networks
  • Interface standards, traffic management, switch operation, routing mechanisms; congestion, flow control, and scheduling mechanisms for the provision of Internet services for the integrated support of multimedia applications
  • IP networking over local, metropolitan, and wide-area networks
  • Provision of quality of service (QoS) for multimedia support to flows transported over IP networks
  • End-to-end performance issues involving TCP
  • Mobile cellular wireless networks
  • Wireless local area networks (WLANs); interconnected WLANs using a mesh backbone; WiMax/LTE
  • Wireless sensor networks
  • Ad hoc wireless networks; ad hoc routing protocols; unmanned vehicle (UAV and UGV)-aided self-configuring multi-tiered mobile wireless networks for network-centric C4ISR combat and disaster-relief/security systems, and for networked sensor systems; UAV-aided Mobile Backbone Networks (UAV-MBNs)

Key networking concepts, applications, traffic models, traffic management procedures, design, and performance evaluations for test cases are demonstrated using the PC-based IRI PLANYST™ computer network simulation and analysis program, and the new IRI UV-MBNP simulator for QoS-oriented mobile ad hoc wireless networks and C4ISR systems.
