Exam 3: Wireless Sensor Network Applications and Challenges

In __________sensor network systems, we must balance the information contribution of individual sensors against the cost of communicating with them

__________are nodes that aid in passing traffic from one cluster to another

Following are application areas of wireless sensor networks A: health care B: industrial process control C: military battlefield awareness D: security and surveillance

The challenges in sensor network databases A: limited storage on nodes and high communication costs imply that older data has to be discarded B: sensor tasking interacts in numerous ways with the sensor database system

Each sensor in a sensor network takes___________ measurements of physical phenomena such as heat, sound, light ,pressure or motion

The size of wireless sensor system is limited mostly by A: the cost of maintaining communication links B: the cost of sensor hardware

Wireless Sensor Networks are networks that consists of sensors which are A: distributed in an ad hoc manner. B: These sensors work with each other to sense some physical phenomenon and then the information gathered is processed to get relevant results. C: Wireless sensor networks consists of protocols and algorithms with self-organizing capabilities.

The challenge in sensor network databases is/ are
