Energy Efficient Coverage and Sensor Localization for Scheduling
Sujata Dhumal, Bharathi Shetty · 2019
Wireless Sensor Network (WSN) is the collection of already deployed motes which sense the physical phenomena and pass the sensed information to the sink node. Sink node stores information and send that information to users according to the user needs. Wireless Sensor Network (WSN) have self directed, tiny, low powered devices called sensors. Major issue in wireless network is coverage of area. It checks how the sensing area is monitored by motes. Strategy for coverage needs simultaneous activation of multiple sensor nodes as every location get covered by at least n sensors. Therefore scheduling technique alternatively activate the sensor nodes to reduce energy consumption. Due to battery limitation, utilization of energy is an extensive challenge in sensor network. Only few nodes may determine the network-lifetime in existing approach. The main role of sensor is sending and receiving the whole traffic so their “energy efficient coverage ” is biggest challenge in sensor network. Sensor localization is used to find the x, y coordinates of unknown nodes so that scheduling will get easy to cover the area using that particular nodes location. Scheduling is main concept in which sequence of nodes is important which increases the energy efficiency and network lifetime.
