摘要：The field of wireless sensor networks has received widespread acceptance because of the easedeployment of nodes, no prior installation of infrastructure before deployment and low cost of operation. This hascaused research in WSN to diversify and not only focus on energy conservation but to also look at ways to enhance thedata performance of the network. QoS parameters such as reliability, loss, latency and bandwidth are now at the centerstage of research. This paper focused on reliability in wireless sensor networks. A survey is performed on existingMAC protocols that provide reliability and they shall be classified according to the nature of the reliability theyprovide. There are protocols that provide node to node reliability and those that provide end to end reliability. We shallthen analyze challenges associated with these existing mechanisms then propose future research directions.
