Generally, various traffic requirements in wireless sensor network are mostly dependent on specific application types, that is, eventdriven, continuous, and query-driven types. In these applications, real-time delivery is one of the important research challenges. However, due to harsh networking environment around a node, many researchers usually take different approach from conventional networks. In order to discuss and analyze the advantage or disadvantage of these approaches, some comprehensive survey literatures were published; however they are either out of date or compiled for communication protocols on single layer. Based on this deficiency, in this paper, we present the up-to-date research approaches and discuss the important features related to real-time communications in wireless sensor networks. As for grouping, we categorize the approaches into hard, soft, and firm real-time model. Furthermore, in all these categories, research has been focused on MAC and scheduling and routing according to research area or objective in second level. Finally, the article also suggests potential directions for future research in the field.

“…Thus they introduce a fault-tolerant real-time routing protocol FT-SPEED. In FTSPEED [5], void announces scheme is centered to keep the packets making the void through one path to the routing path. To send the packet around two sides of the void to ensure that packet to be delivered instead of just being dropped, FT-SPEED presents the void bypass scheme.…”

Wireless sensor network (WSN) [1] is based on distributed event-based system that is different from the traditional communication network. The main goal of the network is to deliver a data packet with the highest efficiency and quality of service. In WSN, Quality of service (QoS) [2] is an important performance indicator, therefore the QoS routing protocols are designed to provide more efficiency and quality of service. Here they concentrate on SPEED [3] protocol (Stateless Protocol for End to End Delay) is a QoS based protocol and which provides efficiency, softness-real time communication, desired delivery speed and a low overhead over the network. MMSPEED [4] is another multi-path multi SPEED protocol, which provides more efficiency and minimal control overhead over the network. This paper represents SPEED protocol and a comparative study on several versions of SPEED protocols.

“…To be general, due to the highly dynamic link and route characteristics the idea of per-flow reservation appears to be non-scalable in a WSN, hence SPEED might not be scalable well for large WSNs. FT-SPEED [28], as an extension of SPEED, is proposed to handle the void problem caused by high sensor failure probability in WSN. In FT-SPEED, a void announce scheme is designed to prevent the packets reaching the void through other routing path.…”

Recent advances in wireless sensor networks have led to rapid development of real-time applications. Many routing protocols have been specifically designed for these applications where real-time guarantee is an essential design issue. In this paper, the state of the art in real-time routing protocols for WSNs is surveyed, along with the highlights of the advantages and performance issues of each routing protocol and algorithm. In addition, the paper concludes with classification of recent real-time routing protocols and discusses open research issues.
