摘要：Energy efficiency and its optimization are of paramount importance in data transmission in Wireless Sensor Networks. The lifetime of the deployed sensor node should be maximized with even distribution of the energy across the network so that the data transmitted is not lost .The MS helps in enhancing the lifetime of the network by reducing the energy spent in long distance transmission. The introduction of RN helps in storage and data transmission from CH to MS. In the proposed protocol I-EADC_RN, the field is divided into two regions Sensing region[A] and Storage region[B]. The nodes deployed within the storage region are called RN. The nodes deployed in the sensing region participate in CH selection based on average energy computed from the neighboring nodes. The RN store the collected data and transmit it to the MS when the MS comes near to them. The objective of the proposed algorithm is to maximize the effective lifetime of the network with the help of RN and MS, reduce energy hole problem with efficient distribution of energy among the network with the help of efficient competition radius assignment and by efficient mean of data transmission with the help of relay node selection based on energy spent in transmission and reception and the minimization of data loss with the help of data storage in the RN.
