Decentralized
energy efficient propagation protocol [DEEP]: DEEP is used for
identifying a head and the
members. The algorithm works as follows
1. Initialize: when network is
created one of the node in the network will be made as cluster head. The
cluster head sends a signal known as cluster head declaration signal to all the
nodes which are in the range ’ . This is used for identifying the members of
the cluster. The cluster head sends cluster head exploration to all the nodes
which are in the range dr1 and dr2. This is done to identify a new cluster
head.
2. Repeat : even though many
nodes receive the cluster head exploration only one node fro which the equation
ERC1 < ER < ERC2 can become the candidate of the cluster head.
‘ER’ is the energy of cluster
head exploration and
‘ERC!’=Pout – ηwd 1
‘ERC2’=Pout–ηwd 2
η, w, n are dependent on environment factors.
The new candidate sends cluster
head declaration for all the nodes in the range dr. if a node receives multiple
cluster head declaration which ever signal is having higher energy will be
chosen as cluster head. The other candidates will be eliminated.
3. Conclusion: if there are not
enough members in a cluster member exploration/search signal will be generated
atleast if a node does not receive any signal member exploration or search
signal will be generated.
