Objectives: The Application specific protocols in the Wireless Sensor Networks (WSN) are developed to achieve specific goals such as delay, energy utilization and throughput. Methods: In real time scenario, the sensor node generates valuable data and it needs to be communicated to the sink reliably without any loss of information. In this paper the transport layer issue, end to end reliable data transmission has been evaluated by implementing the Reliable Routing Medium Access Control (ReRMAC) protocol. The ReRMAC uses functionality of network layer and MAC layer for achieving the reliability as well as minimizing the energy utilization. Findings: In order to recognize the congestion, the queue size of each node in the network is estimated and compared with a queue threshold value. If the node is identified as congested one, then the node does not take part in the current data transmission. Moreover, the nodes in the network are reconfigured by reschedules the routes to destination. It ensures the link quality for error free data transmission. The performance of the proposed ReRMAC is compared with the existing stated ones and it improves the link reliability and energy efficiency in an optimum manner. Improvement: This work can be further addressed by optimization issues while integrating more than one layer at the same time.
