Node cooperation is considered in this paper in the existence of two relaying protocols i.e. "Amplify and Forward (AF)" also called "Store and Forward (SF)" and the second relaying protocol is "Decode and Forward". The two stated protocols are different from each other and perform different operations on received data before retransmitting to next hop. Also the selection of each protocol is varying in accordance to the distance of a sensor node from the destination node (RF source). It is suggested in this literature that a relay node close to the source node will employ Decode and Forward and if it is close to the destination node, then Amplify and forward will be employed.
