Q321.
What is the best path from N1 to N3 in dynamic source routing?

a.

N1 – N4 – N2 – N3

b.

N1 – N4 – N5 – N4 – N1 – N2 – N3

c.

N1 – N4 – N5 – N3

d.

N1 – N2 – N3

Discuss
Answer: (d).N1 – N2 – N3 Explanation:Dynamic source routing initiates by broadcasting a packet to nodes N2 and N4. N2 broadcasts request packets to N3 and N5. N3 identifies itself as the target. N5 forwards the packets to N4 and N3. The nodes which received the request packet for a second time discard the request packets. N3 identifies two routes N1-N2-N3 and N1-N4-N5-N3. N3 returns the path N1-N2-N3 in reverse order since it is the shorter route.
Q322.
Which among the following options should replace the labels ‘A’, ‘B’, and ‘C’?

a.

Cross layer controller, Interface to network, Interface to node

b.

Cross layer controller, Interface to node, Interface to network

c.

Interface to node, Cross layer controller, Interface to network

d.

Interface to network, Cross layer controller, Interface to node

Discuss
Answer: (c).Interface to node, Cross layer controller, Interface to network Explanation:Cross layer implementation on node level is desired to alter the threshold on individual wireless connections, to dynamically limit resources available at the MAC layer, and to improve the error performance of encoding schemes. Cross-layer implementation on the network level is desired to improve the quality of service and effective usage of resources.
Q323.
What type of optimisation technique is represented in the following diagram?

a.

Fuzzy Logic

b.

Hidden Markov Model

c.

Case Based Reasoning

d.

Evolutionary Algorithm

Discuss
Answer: (a).Fuzzy Logic Explanation:Fuzzy Logic is a many valued logic in which the value assigned to variable ranges between completely true to completely false. It is applied for frequently changing parameters or inaccurate parameters. It utilizes concepts such as enrolment capacities, semantic factors, and a central base.
Q324.
Which among the following statements holds true about the give graph?

a.

The energy required per bit increases exponentially with exponential increase in bits per Hertz

b.

The energy required per bit increases linearly with exponential increase in bits per Hertz

c.

The energy required per bit increases linearly with linear increase in bits per Hertz

d.

The energy required per bit increases exponentially with linear increase in bits per Hertz

Discuss
Answer: (d).The energy required per bit increases exponentially with linear increase in bits per Hertz Explanation:The graph shows that the energy required per bit increases linearly with exponential increase in bits per Hertz. The cost of energy varying from one to two bits per Hertz is equal to the variation from six to sever bits per Hertz. Bits per Hertz can be a valid measure for spectrum efficiency provided perfectly stable channel and power are available.
Q325.
Which among the given conditions is represented in the following diagram?

a.

Hyperbola one receiver and source in the same plane and the second receiver in another plane

b.

Hyperbola with two receivers and source in the same plane

c.

Hyperbola with two receivers in the same plane and source in another plane

d.

Hyperbola with each receiver in one plane and a source in another plane

Discuss
Answer: (c).Hyperbola with two receivers in the same plane and source in another plane Explanation:The time difference of arrival approach involves computing the time difference between the reception of a signal at one location and the reception of the same signal at a different location. The hyperboloid curve of time difference of arrival approach is drawn by considering the speed of propagation and difference between the arrival times of the same signal at two receivers. When the receivers and the source are present in the same plane, the hyperbola appears V-shaped with an axis of symmetry through the two receivers.
