What is a leach protocol?
LEACH is a hierarchical routing protocol used in wireless sensor networks to expand the network lifetime. In the LEACH protocol, sensors arrange themselves in a cluster, and a single node of these nodes performs a cluster head. LEACH is capable of adapting, self-organizing, and clustering protocol.
What is Leach protocol in WSN?
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 two phases in Leach protocol?
With similar to LEACH protocol, LEACH-C has two phases: setup phase and steady state phase. In setup phase, Base Station selects the Cluster Head (CH) with the help of average node energy, location and energy level to base station.
What are the advantages and disadvantages of LEACH protocol?
LEACH is a MAC protocol, it contains many advantages like it does not need any control information, it saves energy, it is completely distributed and also contain many disadvantages like if cluster head dies then cluster become useless, clusters are divided randomly etc.
Which is the first clustering protocol?
Out of these, clustering algorithms have gained more importance, in increasing the life time of the WSN, because of their approach in cluster head selection and data aggregation. LEACH (distributed) is the first clustering routing protocol which is proven to be better compared to other such algorithms.
Where is LEACH protocol used?
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 base station in WSN?
The base stations are one or more components of the WSN with much more computational, energy and communication resources. They act as a gateway between sensor nodes and the end user as they typically forward data from the WSN on to a server.
What are the advantages and disadvantages of Leach protocol?
What is the main limitation of Leach protocol?
One of the biggest disadvantage of LEACH is that when due to any reason Cluster head dies, the cluster will become useless because the data gathered by the cluster nodes would never reach its destination i.e. Base Station. 3. Clusters are divided randomly, which results in uneven distribution of Clusters.
What is Leach Fullform?
In which protocol clusters are formed?
Central aggregation: based on a cluster-based network architecture formed through a clustering protocol [7]. The network is divided into clusters and in each cluster a leader node (cluster head) is elected to manage all nodes in the cluster and aggregate collected data.
