Contemporary development in wireless sensor networks has haltered the expeditious advances in real-time applications. Numerous routing protocols were proposed for these applications however design issue is real-time guarantee. In this paper, the futuristic in WSN routing protocols is surveyed whilst emphasizing on merits and performance issues. The paper provides a classification of real-time routing protocols and highlights another major issue in this direction, i.e. reliability along with other research issues.
