“…It uses metadata to establish multi‐path routing while reducing the energy consumption and a cost function that evaluates the consumption of the transmission links which trades off the relationship of energy and delay. To support multiple flows, a protocol called AdamRTP is proposed such that it is able to make easier the process of transmitting real‐time multimedia over WSNs by splitting the multimedia source stream into smaller independent flows using an multiple description coding (MDC)‐aware encoder, then sending each segment to the destination using joint/disjoint path(s). Dynamic adaptation techniques, such as changing the number of flows and rate adaptation are also used therein.…”

“…For this comparison, we adapt two different applications with (2,2)‐firm and (2,4)‐firm streams. Also, a comparison in evaluation is performed by introducing SPEED, our previous work and POWER‐SPEED . The reason to select SPEED is simply by employing geographic routing concept and many citations in this research area.…”

“…As research in multimedia sensor networks is currently going on, it is commonly recognized that applicationspecific requirements such as real-time delivery should be defined as well as supported by the networks. With corresponding to the needs above, numerous approaches [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] have been proposed to employ validated previous related works in wireless sensor networks. However, because a sensor node has several rigid constraints such as error-prone wireless communication and low computing power, we need significant changes or modifications therein.…”

In this paper, we propose a novel scheme of how to efficiently and reliably deliver multimedia real-time streams in wireless sensor networks. To specify the property of streams, a multimedia stream is modeled as an (m,k)-firm stream that is known to have the characteristics of weakly hard real-time system. In addition, a distributed, measurement-based routing scheme for (m,k)-firm streams is newly proposed while considering several constraints on node as well as on communication medium. Simulations and their analysis are provided to validate the suitability of traffic modeling, reduced dynamic failure probability, and extended network lifetime when the proposed routing protocol is employed.As motivated by the aforementioned needs, we consider the (m,k)-firm model [21] in wireless sensor networks. A real-time stream with the (m,k)-firm guarantee requirement demands that at least m out of any k consecutive packets in this stream must meet their respective deadline. Two well-known examples for a (m,k)-firm stream are video and audio streams, because they are tolerant to packet loss but sensitive to real-time delivery. The concept of (m,k)-firm is appropriate for wireless sensor networks due to minimum requirement and its inevitable packet loss. Packet loss is naturally expected because of the poor wireless connectivity and bandwidth constraints on wireless sensor networks. Despite of the apparent suitability of the model, to the best of the authors' knowledge, the research in [16] has been only addressed to date except for the schemes developed by our research group [22,23].Although our previous work was proposed to introduce and support a (m,k)-firm model in wireless multimedia sensor networks, our contribution was limited to develop the appropriate scheduling for the traffic model. Thus, in consequence of our achievements, we propose a scheme on how to efficiently and reliably model a (m,k)-firm traffic in wireless multimedia sensor networks and employ routing algorithm to guarantee real-time delivery. In the proposed scheme, both m and k values are determined by the density

Recently, reliable data transport in wireless sensor network becomes very crucial for real-time application with different application requirements. Real time multimedia application requires large bandwidth and big memory in the network in order to send video data and needs to arrive at destination in time. Data that arrives at the receiver not in time will be discarded and cannot be played because loss recovery through retransmission of data loss may introduce long delays. Therefore, an implementation of transport protocol in wireless sensor network for multimedia application is a challenging task. Traditional protocol likes TCP and UDP cannot directly applied for real-time communication over wireless sensor network because the lack of functions of real-time services and the unique characteristics of sensor node itself. However there is another transport protocol which is the Stream Control Transmission Protocol (SCTP) that provides multi-stream service for single connection. This feature can be applied for video transmission according to the type of frame to be transmitted. Thus, to achieve the high reliability video data delivery, the advantages of multi-streaming features in SCTP with the combination of low data rate wireless sensor networks will be applied for the new proposed transport protocol. Besides that, transport protocol algorithm also allows maximum network lifetime due to the limited operating lifetime of sensor node and multimedia also is a highly power consuming task. Thus, to prolong the lifetime of wireless sensor network, an efficient transport protocol need to support reliable message delivery and provide congestion control in the most energy efficient. This paper focuses on the existing transport protocols for real-time application and the future protocol that provides the entire requirement of transport protocol.
