Because leader role is energy greedy consuming, PEGASIS ensure that at each transmission round a new node is selected as leader in order to distribute energy load.
i] consecutive transmission rounds rather than one transmission round as in PEGASIS.
PEGASIS and obstacle avoiding algorithm is integrated and a new agent object is created called MyAgent.
The proposed methodology EECP over rides existing methodology by using PEGASIS for avoiding nodes death and STEM for nominal power consumption.
It is observe that LEACH-IMP technique has better number of packets received as the number of sensor nodes increases when compared to the PEGASIS
In contrast, LEACH and PEGASIS
perform poorly when the sink is inside the sensor field.
And the future we use PEGASIS
algorithm in wireless sensor network.
When a is infinite, the topology derived by EEPB is the same as PEGASIS
The leaf nodes of the data gathering are the non-LCL nodes in each grid block, which either directly forward their data to the LCL (GBE-Cluster-DG tree) like in a LEACH cluster or by forming a chain of nodes involving the LCL (GBE-Chain-DG tree) as in PEGASIS
 that is a chain based routing protocol for wireless sensor networks, a chain is formed among the sensor nodes so that each node receives from a previous neighbor and transmits to a next neighbor.
The main idea of PEGASIS
is for each node to only communicate with their close neighbors and take turns to be a leader for data transmission.
forms a single chain of sensor nodes and the same chain is used for all the rounds of data communication.
