In recent years WSN has become evident in
research areas. Wsn is a collection of several small nodes which can sense,
accumulate and disseminate data for multiple applications. The sensor nodes
have a limited transmission range, processing and capacity abilities and their
vitality assets are additionally constrained. Routing protocols are in charge
of keeping up the routes in the network and need to guarantee reliable multi
hop communication in these constraints. In hierarchical architecture, nodes
with higher energy can be utilized to handle and transmit the data while nodes
with lower energy can be utilized to carry out the sensing in the closeness of
the objective. This implies that cluster creation and assignment of special
tasks to cluster heads can enormously add to generally framework versatility,
lifetime, and efficiency of energy. Lower vitality utilization, by carrying out
data aggregation and fusion the main goal is to diminish the number of
transmitted messages to the BS which can be done by hierarchical routing. In
this kind of routing there are mainly two-layer routing, one is utilized to
choose the cluster heads and the latter is utilized for routing. In this paper
we present a survey on these protocols as well as their merits and demerits. - Seemore at:
