This protocol is classified into rounds; every round composed of two phases;
Set-up Phase
(1) Advertisement Phase
(2) Cluster Set-up Phase
Steady Phase
(1) Schedule Creation
(2) Data Transmission
A. Setup Phase: Every node selects independent of other nodes if it will become a CH or not. This selection takes into consideration when the node behaved as a CH for the last time. In the advertisement phase, the CHs inform their neighboring node with an advertisement packet that they become CHs. Non-CH nodes take the advertisement packet with the strongest obtained signal strength. In the next cluster setup phase, the member nodes inform the CH that they become a member of that cluster with "join packet" has their IDs utilizing CSMA. After the cluster-setup sub-phase, the CH knows the no. of member nodes and their IDs. Depending on all messages obtained within the cluster, the CH produces a TDMA schedule, take a CSMA code in a random way, and forward the TDMA table to cluster members. After that steady-state phase starts.
B. Steady-state phase: Data transmission starts; Nodes forward their data during their assigned TDMA slot to the CH. This transmission utilizes a minimum amount of energy (selected depending on the obtained strength of the CH advertisement). The radio of every non-CH node can be turned off until the nodes assigned TDMA …show more content…
It builds the residual energy of node as the significant metric which selects whether the nodes turn into CH or not after the first round. Similar to LEACH protocol, E-LEACH is classified into rounds, in the first round, each node has the same possibility to turn into CH, that mean nodes are chosen as CHs in a random way, in the next rounds, the residual energy of every node is different after one round communication and taken into consideration for choosing the CHs. That mean nodes have more energy will become a CHs instead of nodes with less
