What is Leach in wireless sensor network?
Low-energy adaptive clustering hierarchy (“LEACH”) is a TDMA-based MAC protocol which is integrated with clustering and a simple routing protocol in wireless sensor networks (WSNs).
What are the applications of wireless sensor networks?
WSN is deployed in numerous fields such as animal tracking, precision agriculture, environmental monitoring, security and surveillance, smart buildings, health care and so on.
Which protocol is used for WSN in home networking?
Most of the applications of WSN uses route discovery base routing protocols e.g. AODV, DSR & OLSR. The performance of these protocols is compared in different scenarios on the basis of throughput, delay and congestion.
Which is the most popularly used wireless technology used by wireless sensor networks?
ZigBee operates at 2.45 GHz, which gives a shorter range than sub-1GHz, but because of the mesh the coverage can be good and reliable with redundant paths, as long as there are enough nodes in the network. An advantage is that 2.45 GHz is a world-wide license free frequency.
What is Leach protocol?
Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is a TDMA based MAC protocol. The principal aim of this protocol is to improve the lifespan of wireless sensor networks by lowering the energy consumption required to create and maintain Cluster Heads.
What is Pegasis protocol?
PEGASIS – Power Efficient Gathering in Sensor Information Systems is one such hierarchical routing protocol which follows a chain based approach and a greedy algorithm. The sensor nodes organize themselves to form a chain. If any node dies in between then the chain is reconstructed to bypass the dead node.
What is sensor network applications?
Wireless Sensor Network has been widely used in many areas especially for surveillance and monitoring in agriculture and habitat monitoring. Environment monitoring has become an important field of control and protection, providing real-time system and control communication with the physical world.
WHAT IS sensor and its applications?
The sensor is an electronic device that measures physical attributes such as temperature, pressure, distance, speed, torque, acceleration, etc., from equipment, appliances, machines and any other systems. Applications classify sensors, Property sensed, Technology used and Systems where they are deployed.
What is the best routing protocol for sensor networks?
6.3. Hierarchical Routing Protocols
- LEACH (Low Energy Adaptive Clustering Hierarchy)
- PEGASIS (Power-Efficient Gathering in Sensor Information Systems)
- TEEN (Threshold Sensitive Energy Efficient Sensor Network Protocol)
- DirQ (Directed Query Dissemination)
What are routing strategies in wireless sensor networks?
Routing protocols for wireless sensor networks can be classified as data-centric, hierarchical or location-based [7]. In these three categories, source, shortest path, and hierarchical-geographical strategies play an important role to develop all of the routing protocols.
Which type of technology is used in wireless networks?
IEEE 802.11: WiFi WiFi uses radio waves (RF) to allow two devices to communicate with one another. The technology is most commonly used to connect Internet routers to devices like computers, tablets and phones; however, it can be used to connect together any two hardware components.
Which technology is installed by wireless man?
Many companies deploy wireless MANs using wireless LAN standards, such as 802.11 and Wi-Fi.
