2.5 Proposed Architectures for SDN in WSN The novel idea of exploiting OpenFlow technology to address reliability issues in sensor networks was presented by (Arif Mahmud and Rahim Rahmani, 2011) at the IEEE International Conference on Computer Science and Network Technology while the first architectural proposal was presented by (Luo et al., 2012) in the form of Software Defined Wireless Sensor Network (SD-WSN). Up until now, very limited research work is carried out in this area. Some of the…

31. Which addressing mode is requirement of reference memory calculated for operands? a. Indexed Mode b. Immediate Mode c. Indirect Mode d. Register Mode ANSWER: d. Register Mode 32. What kind of addressing resemble in terms of 8 low - order bits of memory address? a. Two- page Addressing b. Zero - page addressing c. Indexed Addressing d. None of the above ANSWER: b. Zero - page Addressing 33. How is the actual address of base-register designed? a. By addition of index register…

The desert offers an opportunity to leave old identities behind and start over. The new California Garden of Eden can be seen in Gary Reger’s The Deserts of Los Angeles: Two Topologies, Mary Austin’s Land of Little Rain, and Joel Sternfeld’s After a Flash Flood, Rancho Mirage, CA. California’s original Garden of Eden has been consumed due to the interference of man, however the original Garden traces can be found within the desert…

lectures. During his lectures he has presented amazing work at over 100 different times at over 60 institutions in nine different countries. He also published 40 articles and has been the editor of the NAM Newsletter and a columnist with the journal Topology Atlas. His website The Complete Abridged Scott Williams won the best of the web award. In 2004, Science spectrum magazine and career communications Group Inc. had awarded Scott W. Williams as one of the most important Blacks in research…

values of sensors of each robot individually and processing those values is impractical. So, these sensors can all be connected using Zigbee modules and a network can be formed of such sensors. These modules can be then connected in a star or tree topology where each module is connected to the central Coordinator module. The coordinator is connected to a main system where the values of all the sensors are input and processing is done. Then, according to the task of the robot, different control…

the information on the extranet, authentication protocols are used, such as a user name and password that allows an individual user to access the information. Network topology refers to the structure of the network that describes how the communication links and hardware devices are set up. Three different types of network topology include the star network, the bus network, and the mesh network. In a star network all of the network devices connect to each other through one single device called a…

emphasizes the relationship between the reader and the space and time of the work. To specify, when the readers come across the comics, the changes of space and time of the narrative arranged by the author can be realized. Moreover, in terms of the topology of space and time, different narratives can interact with and comments for each other. For instance, when the character telling a story to someone else in one narrative, there occurs another narrative. And the comic can show the two…

which Ethernet operates by. The original 802.3 standard is 10mbps. Commonly, Ethernet networks transmit data in packets, as previously stated. A packet can be a minimum size of 72 bytes or a maximum of 1518 bytes. The most common topology for Ethernet is the star topology, which will be explained later in this report. c. 802.5 – Token Ring Originally, token ring operated at a speed of…

communication link. An example of its use is in the pressure measuring systems. The advancement in technology lead to the need of more efficient topologies. The developers started making cost-effective protocols for these designs. For example a Star topology finds its use in easily scaling the number of lights in a room or a router in a house can use the Mesh topology to overcome shadowing and ensure uniform signal strength throughout the house. The major area of concern is the security of these…

Dynamic Topology VANET have high mobile topology [8]. The communication joins between nodes changes quickly. Correspondence between two nodes stays for less time. For instance if two vehicles moving far from each other with a velocity of 25m/sec and if the transmission reach is around 250m, then the connection will last for just 5 seconds ( 250m/50ms-1). So this how very dynamic topology is present in VANET. 1.1.2 Continuous Disengaged Network VANETs are prone to transmission errors [8],…
