Abstract: Wireless sensor networks (WSN) have generated tremendous interest among researchers these years because of their potential usage in a wide variety of applications. Sensor nodes are inexpensive portable devices with limited processing power and energy resources. Sensor nodes can be used to collect information from the environment, locally process this data and transmit the sensed data back to the user. In the case of Two-Hop Acknowledgement (2H-ACK), two nodes are involves to make the copy of same data packets until first node receive the acknowledgement to increase the reliability of network, but still this technique have a problem of data packet loss. This thesis proposes a new reliability model in order to insure reliable data deliveries with the name of Three Hop-Reliability Model (3H-RM), in which every sender node of each group of three layers will maintain the copy of same successful transferred data packets without creating extra burden on the networks. The new model is designed that aims at providing 100% reliability when possible as well as minimizing overhead and network delay.
