Introduction
WS N-monitor physical or environmental
conditions.
Energy plays important role in WS N. Aim of routing protocols in WS N
Examples of routing protocols -
LEACH,PEGASIS etc. LEACH-cluster based routing protocol in
WS N.

LEACH protocol Hierarchical routing protocol.
Protocol is divided into rounds, each round
consists of two phases
Setup phase
1.Advertisement phase
2.Cluster setup phase
Steady state phase
1.Schedule creation.
2.Data transmission.

LEACH(continued«.)
Disadvantages of LEACH
Random CH selection(don¶t consider the
energy consumption metric) It can¶t cover large area.
CHs are not uniformly distributed.

Improvement on leach protocol
1.E-LEACH protocol RE of node as metric for CH selection.
2.TL-LEACH protocol Another CH is used as relay station between for
CH and BS.
3.M-LEACH protocol
Select optimal path between CH and BSthrough other CH¶s.
4.LEACH ±C protocol

V-LEACH
In V-LEACH ,the
cluster contains
Cluster head
Vice-cluster head
Cluster nodes
VICE-CH

V-LEACH(Continued«..)
Advantages over LEACH Protocol
Even CH dies the cluster will work with
vice-CH.
The over all network life time also is more.

Conclusion
By simulation result we can say that
V-LEACH generates less number of messages
than LEACH. The network remaining energy is more
compared to LEACH.
