1 AODV https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

2 ZigBee - Network layer 1 The routing protocol used by the network layer is AODV https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

3 IEEE 802.11s - Routing protocols 1 802.11s defines a default mandatory routing protocol (Hybrid Wireless Mesh Protocol, or HWMP), yet allows vendors to operate using alternate protocols. HWMP is inspired by a combination of Ad Hoc On- demand Distance Vector|AODV (RFC 3561) and tree-based routing. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

4 Mesh networking - Examples 1 Zigbee digital radios are incorporated into some consumer appliances, including battery-powered appliances. Zigbee radios spontaneously organize a mesh network, using AODV routing; transmission and reception are synchronized. This means the radios can be off much of the time, and thus conserve power. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

5 Ad hoc On-Demand Distance Vector Routing 1 'Ad hoc On-Demand Distance Vector (AODV) Routing' is a routing protocol for mobile ad hoc networks (MANETs) and other wireless ad hoc networks. It is jointly developed in Nokia Research Center, University of California, Santa Barbara and University of Cincinnati by C. Perkins, E. Belding-Royer and Samir Das|S. Das. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

6 Ad hoc On-Demand Distance Vector Routing 1 AODV is the routing protocol used in ZigBee. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

7 Ad hoc On-Demand Distance Vector Routing - Workings 1 Other AODV nodes forward this message, and record the node that they heard it from, creating an explosion of temporary routes back to the needy node https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

8 Ad hoc On-Demand Distance Vector Routing - Workings 1 The advantage of AODV is that it creates no extra traffic for communication along existing links. Also, distance vector routing is simple, and doesn't require much memory or calculation. However AODV requires more time to establish a connection, and the initial communication to establish a route is heavier than some other approaches. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

9 Ad hoc On-Demand Distance Vector Routing - Technical description 1 The major difference between AODV and other on-demand routing protocols is that it uses a destination sequence number (DestSeqNum) to determine an up-to-date path to the destination https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

10 Ad hoc On-Demand Distance Vector Routing - Technical description 1 This helps in storing an active path at the intermediate node as AODV does not employ source routing of data packets https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

11 Ad hoc On-Demand Distance Vector Routing - Advantages and disadvantages 1 Another disadvantage of AODV is unnecessary bandwidth consumption due to periodic beaconing. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

12 Érik Comas - Formula One 1 Senna jumped from his own car, ran over to Comas, shut down his engine and held Comas' head in a stable position until the doctors could arrive.[http://br.youtube.com/watch?v=OaOD VWmbfMI YouTube.com] When Senna died at Imola in 1994, Comas was so shocked he decided to not participate in the restart of the race, mainly because of what happened at Spa two years earlier. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

13 Dynamic Source Routing 1 'Dynamic Source Routing' ('DSR') is a routing Communications protocol|protocol for wireless mesh networks. It is similar to AODV in that it forms a route on-demand when a transmitting computer requests one. However, it uses source routing instead of relying on the routing table at each intermediate device. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

14 Ns (simulator) - Design 1 The large majority of its users focuses on wireless simulations which involve models for Wi-Fi, WiMAX, or LTE for layers 1 and 2 and routing protocols such as OLSR and AODV. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

15 Babel (protocol) 1 Babel is based on the ideas in Destination- Sequenced Distance Vector routing (DSDV), Ad Hoc On-Demand Distance Vector Routing (AODV), and Cisco's Enhanced Interior Gateway Routing Protocol (EIGRP), but it uses a variant of Expected Transmission Count (ETX) link cost estimation rather than a simple hop-count metric. It employs several techniques to ensure the absence of routing pathologies, such as routing loops. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

16 Optimized Link State Routing Protocol - Other approaches 1 In bandwidth- and power-starved environments, it is interesting to keep the network silent when there is no traffic to be routed. Reactive routing protocols do not maintain routes, but build them on demand. As link-state protocols require database synchronisation, such protocols typically use the distance vector approach, as in AODV and DSDV, or more Ad Hoc approaches that do not necessarily build optimal paths, such as Dynamic Source Routing. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

17 Routing in delay-tolerant networking 1 In these challenging environments, popular ad hoc routing protocols such as Ad hoc On-demand Distance Vector|AODVC https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

18 Guernsey (clothing) - Use in the British Armed Forces 1 The guernsey was first widely used in the rating uniform of the 19th century United Kingdom|British Royal Navy.The History of Rating Uniforms[http://www.royal- navy.mod.uk/server/show/nav.3772] accessed 6 May 2008Traditional Guernsey knitwear and genuine Alderney sweaters from the Channel Islands[http://www.channeljumper.com/?gclid=CJ WNtM2TkpMCFQSKMAodvlxoYQ] accessed 6 May 2008 It is said that guernseys were worn at the Battle of Trafalgar, (although these were probably made from woolen cloth, rather than knitted) https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

19 Delay-tolerant networking - Routing 1 In these challenging environments, popular ad hoc routing protocols such as Ad hoc On-demand Distance Vector|AODV and Dynamic Source Routing|DSR fail to establish routes https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html

20 Hazy-Sighted Link State Routing Protocol - Why a link-state protocol? 1 The inventors of HSLS claim that routing protocols fall into three basically different schemes: proactive (such as OLSR), reactive (such as AODV), and algorithms that accept sub-optimal routings https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html
