1. State whether the following statement is true or false.
Statement: Coverage in WSN is defined as the area-of-interest that is covered satisfactorily.

a. True
b. False

Answer: a
Explanation: In Wireless Sensor Networks (WSN), “coverage” refers to how well an area-of-interest is monitored or sensed by sensors. If the area is sufficiently monitored, it is considered satisfactorily covered.

---

2. If transmission range >= 2 * sensing range,

a. Coverage implies connectivity
b. Coverage implies greater coverage
c. Both (a) and (b)
d. None of these

Answer: a
Explanation: When the transmission range is at least twice the sensing range, any area covered by sensors will also maintain network connectivity, meaning sensors can communicate with each other effectively.

---

3. Forest fire monitoring in WSN is an example of which type of reporting?

a. Event driven
b. On-demand
c. Scattered
d. None of these

Answer: a
Explanation: In forest fire monitoring, sensors send data when a fire-related event is detected, which is a classic example of event-driven reporting.

---

4. State whether the following statement is true or false.
Statement: Objective of coverage in WSN is to use minimum number of sensors and maximize network lifetime.

a. True
b. False

Answer: a
Explanation: One key goal of WSN design is to optimize resource use by deploying the fewest sensors necessary while maximizing the overall lifespan of the network.

---

5. What is the full form of AUV in the context of mobile wireless sensor networks?

a. Aerial and Underwater Vehicle
b. Ambient and Underprivileged Vehicle
c. Autonomous Underwater Vehicle
d. None of these

Answer: c
Explanation: AUV stands for Autonomous Underwater Vehicle, which is commonly used in underwater sensing applications in mobile wireless sensor networks.

---

6. In mobile wireless sensor networks, the sensor nodes are capable of __________ and measuring the condition of their surrounding environments.

a. collaborating with one another
b. destroying one another
c. Both (a) and (b)
d. None of these

Answer: a
Explanation: Sensor nodes in mobile WSNs collaborate with each other to collect, share, and report environmental data effectively.

---

7. State whether the following statement is true or false.
Statement: In mobile sensor networks, the sensor nodes come in close proximity of sink and deliver the data.

a. True
b. False

Answer: a
Explanation: In many mobile sensor networks, mobile nodes collect data and deliver it to the sink node by moving closer, optimizing energy use and reducing transmission delays.

---

8. Which of the following is/are a challenge/challenges in Human-centric Sensing?

a. Energy of devices
b. Participant selection
c. Both (a) and (b)
d. None of these

Answer: c
Explanation: Human-centric sensing involves human participation, so challenges include selecting suitable participants and managing the energy constraints of personal devices.

---

9. Which of the following is/are a feature/features of UAV networks?

a. Mesh or star networks
b. Multi-tasking
c. Large coverage area
d. All of these

Answer: d

---

10. State whether the following statement is true or false.
Statement: Frequently change in network topology is a benefit of UAV networks.

a. False
b. True

Answer: a
Explanation: Frequent topology changes in UAV networks are typically a challenge, not a benefit, as they can cause connectivity and coordination issues.

---

11. Which of the following is NOT a feature of multi-UAV system?

a. Low failures
b. High scalability
c. Low survivability
d. High cost

Answer: c
Explanation: Multi-UAV systems are designed to be robust and survive failures. Therefore, “Low survivability” is not a feature—it’s actually a drawback.

12. State whether the following statement is true or false.
Statement: M2M communications are free of any human intervention.

a. True
b. False

Answer: a
Explanation: Machine-to-Machine (M2M) communications are designed to operate autonomously without human involvement.
