Alessandro Leonardi Wireless s Generations (1/3) Generation 1G 2G 2.5G 3G 4/5G Time 1980s 1990s Late1990s 2000s (2010 full deployment) 2010s Signal Type Analog Digital Digital Digital Digital Access Multiple Access FDMA/FDD TDMA/FDD CDMA/FDD EDGE, GPRS CDMA, W-CDMA, TD-SCDMA MC-CDMA, OFDM Frequency spectrum MHz MHz MHz (PCS) MHZ (varies from diff. countries) Higher frequency bands 2-8GHz Bandwidth 5-20MHz >=100MHz Antenna FEC Optimized Antenna, multiband adapter Convolutional rate, 1/2, 1/3; Smarter Antenna, Multi-band and wideband support Concatenated coding scheme 1

An ad hoc network is a wireless LAN, in which some devices are part of the network only for the duration of a communication session or while in some close proximity to the rest of the network. A mobile ad hoc network (MANET) is an autonomous system of mobile routers (and associated hosts) connected by wireless links forming an arbitrary graph. Routers are free to move randomly and organize themselves arbitrarily; network topology may change rapidly and unpredictably. It may operate in a stand-alone fashion, or may be connected to the Internet. An ad hoc network can be regarded as a spontaneous network : a network that automatically emerges when nodes gather together. 3

4 Ad Hoc s Advantages " Ease of deployment " Speed of configuration (self-organization) " Decreased dependence on the infrastructure Dipartimento di Ingegneria Informatica e delle Telecomunicazioni Applications of Ad Hoc s " Interactive applications Mobile phones and PDAs Wearable devices Outdoor Internet access Location-aware services " Cooperative applications Vehicular services Meeting and classrooms Gaming " Emergency services Infrastructure replacing Rescue data collection " Environmental monitoring Sensor networks " Military environments Tactical Operations Battlefield 4

5 Examples of Ad Hoc s 1. Personal Area s (PANs) 2. Body Area s (BANs) 3. Sensor s Personal Area s (PANs) Created when a group of people come together for some collaborative activity (e.g. exchange things and relay information). Limited extent in space and time. Nodes connected using various wireless technology (e.g., IEEE family). Authentication and trust based on first-person interaction, no administrative services. Hosts not preconfigured. Data rates: 1-10 Mbps. 5

6 Body Area s (BANs) Wireless communication between various components (earphones, microphones, sensors) attached to human body. Possible Applications: transmission of body parameters (blood pressure, pulse rate, body temperature); music entertainment. Features: transmission without interferences; licence free; low transmission power; cheap, tiny and light-weight hardware. Data rates up to 250 Kbps. Sensor s Self-configurable networks made of numerous sensors linked by a wireless medium, which perform distributed sensing tasks. Features: Frequency: variable range Bandwidth: kb/s Transmission power: ~ 1mW Access: many proposals (Aloha and CSMA-based) Sensors are very numerous. Sensors are simple and have scarse power and memory resources. Addressing done by data and area. 6

7 Characteristics and Requirements Autonomous and spontaneous nature of nodes Distributed Algorithms to support reliability, consistency and security of exchanged and stored information Time-varying network topology (no pre-existing infrastructure or central administration) Scalable routing and mobility management techniques to face network dynamics Fluctuating link capacity and network resources Enhanced functionalities to improve link layer performance, QoS network support and end-to-end efficiency Low-power devices Energy conserving techniques at all layers Possible Variations (1/3) Fully Symmetric Environment nodes have identical capabilities and responsibilities Asymmetric Capabilities transmission ranges and radios may differ battery life at different nodes may differ processing capacities may differ Asymmetric Responsibilities some nodes may act as leaders of nearby nodes (e.g., cluster head) 7

8 Possible Variations (2/3) Nodes may co-exist (and co-operate) with an infrastructure-based network Traffic characteristics may differ w.r.t. bit rate time constraints reliability requirements unicast / multicast / geocast Possible Variations (3/3) Mobility patterns may differ people sitting at an airport lounge taxi cabs kids playing military squads PAN environments Mobility characteristics speed predictability direction of movement pattern of movement 8

9 Challenges Broadcast nature of the wireless medium Limited wireless transmission range Hidden terminal problem Exposed terminal problem Capture problem Intruding terminal problem Packet losses due to transmission errors Mobility-induced route changes Mobility-induced packet losses Battery constraints Potentially frequent network partitions Ease of snooping on wireless transmissions Multihopping Data routes may traverse multiple links to reach a destination. It increases overall network capacity since the spatial domain could be reused for concurrent but physically separate sessions. It conserves transmit energy resources reduces interference. r 1 r r 3 4 r 4 9
