17 Questions
What is the objective of Barrier Coverage?
Covering a region with at least one sensor
In K-barrier coverage, how many sensors are required to cover a region?
At least K sensors
What are crossings in terms of coverage maintenance?
Points where sensors meet
What is the key observation made about area coverage in the text?
An area is completely covered if there are at least two disks that intersect and all crossings are covered
What is the relationship between coverage and connectivity in a sensor network, according to the text?
If the communication range is at least twice the sensing range, then coverage implies connectivity
How is a crossing defined to be covered?
If it is within the boundary of a sensor's coverage disk
What is the name of the distributed, localized algorithm proposed in the text for achieving optimal geographical density control?
Optimal Geographical Density Control
What does Strong Coverage imply in the context of Internet of Things?
Covering a region with multiple overlapping sensors
What are the two main types of point coverage discussed in the text?
Random and deterministic
What is the key difference between random and deterministic point coverage, as described in the text?
Random point coverage distributes sensors randomly, while deterministic point coverage does so in a deterministic manner
What is the key condition for a sensor network to be considered connected, according to the text?
Any active node must be able to communicate with any other active node
What is the primary concern when deploying static sensors for area coverage?
Determining the optimal sensor placement and density
If the transmission range of a sensor is twice its sensing range, what can be inferred?
Coverage implies connectivity
What is the primary goal of the coverage problem in wireless sensor networks?
Determining how well the sensing field is monitored or tracked
In the case of mobile sensors, what is the focus of the coverage problem?
Planning the trajectory of the mobile sensors
What is the relationship between sensing range ($r_s$) and transmission range ($r_t$) for most sensors?
$r_t \geq 2r_s$
What is the primary distinction between the coverage problem for static and mobile sensors?
The deployment strategy
