The need for remote monitoring system keeps increasing every day especially in healthcare system. There are three categories of people who are greatly benefitting from this healthcareremote monitoring; these are old people who are unable to go for medical checkups every time, the chronic disease patients whose condition is critical and need to be monitored closely and adequately, the third category are the athletes whom body movements and physiological body functions require a close monitoring for optimum performances and analysis. The reliability ofthe transmitted data has played a great role in the fulldeployment of this technology, especially in healthcare monitoring applications. The reliability is treated in terms of power consumption, end-to-end delay, efficient packet routing, and total throughput of the packet delivery ratio. In this paper, we havereviewed the state-of-the-art reliability approaches and categorizedthem into node-to-node, node-to-sink, and node-to-gateway. Likewise, we have theoretically proposed a reliable routing technique between the sensor nodes and gateway deviceswhich guarantee a successful packet delivery even if the coordinator fails. This research is a guideline for the researchers and industries to work on the suggested current issues and shift the paradigm of packet transmissions in WBAN from only intra-sensor to sensor-gateway.
