N2 - The one among well-known protocols for the data gathering in wireless sensor network is the Power Efficient-Gathering in Sensor Information System (PEGASIS) [1]. In the PEGASIS, the base station (BS) is far away from sensor network. All the sensor nodes form a single chain using greedy algorithm. The leader node is randomly selected among the sensor nodes and transmits aggregated data to the BS. In order to gather data, the leader node sends a small token to the end nodes along the chain, and then non-leader nodes on the chain send the sensing data along the chain toward the leader node from the end nodes. In the PEGASIS, non-leader node's transmission distance decreased. However, still the leader node's transmission distance has not decreased since the BS is far away from the network field. Therefore, the leader node consumes more energy for data transmission than non-leader nodes. If the leader node's energy exhaustion has arisen, the leader node's data transmission is unreliable. As well as, the sensor nodes have to form a re-chaining for the next round. In order to resolve this problem in this paper, we proposed energy based re-transmission of the leader node's neighbor nodes in the PEGASIS. Through our approach, we have proved more high reliable transmission on the same simulation condition. Also, our approach decreases the number of re-chaining during the whole round.
