What is LEACH protocol?

What is LEACH protocol?

LEACH: the low energy adaptive clustering hierarchy 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.

How many phases does LEACH protocol have?

two phases
Protocols LEACH is designed to minimize the energy consumption by distributing the nodes randomly with two phases: setup phase and steady state phase.

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.

Is a 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.

Which is the first clustering protocol?

LEACH (distributed) is the first clustering routing protocol which is proven to be better compared to other such algorithms.

What is spin in WSN?

In WSN, Sensor Protocols for Information via Negotiation (SPIN) is a data centric routing protocol which forwards data to neighbor nodes but it does not ensures the reliable data delivery.

What are the limitations of WSN?

Following are the drawbacks or disadvantages of WSN: ➨As it is wireless in nature, it is prone to hacking by hackers. ➨It can not be used for high speed communication as it is designed for low speed applications. ➨It is expensive to build such network and hence can not be affordable by all.

What is Hybrid routing?

Hybrid Routing Protocol (HRP) is a network routing protocol that combines Distance Vector Routing Protocol (DVRP) and Link State Routing Protocol (LSRP) features. HRP is used to determine optimal network destination routes and report network topology data modifications.

Which protocol is used in clustering based WSN?

The hierarchical routing protocol divides nodes into different clusters, each of which consists of cluster head and cluster members. The cluster members gather information and form a simple many-to-one communication which does not need redundant routing information, and data are fused at the cluster head.

Why choose K-means clustering?

The K-means clustering algorithm is used to find groups which have not been explicitly labeled in the data. This can be used to confirm business assumptions about what types of groups exist or to identify unknown groups in complex data sets.
