“…The first three tasks (a to c) are entwined and have been addressed in many works [3], [12], [16], [2], [9]. The design of efficient relaying strategies for fountain codes have recently deserved the attention of the communication community due to the development of network coding techniques [15], [1], [6]. To the knowledge of the authors, this paper is the first one addressing the overflow issue.…”

“…In a WSN, the capacity of each channel in a path is unknown prior roll-out and even during the lifetime of the network: the nodes are usually scattered across the monitored area in a random way and the environment may vary. Fountain codes are a promising solution to provide robustness here [5], [14], [1], [6]. Indeed, they are rateless, i.e.…”

Abstract-This paper concentrates on the proper use of fountain codes for the transmission of sporadic data in a wireless sensor network (WSN). Fountain codes offer great perspectives for the self-organization of WSNs: they self adapt to the channel error rate without control packets. Deploying fountain codes in a WSN raises two problems. First, the size of the data transmitted by a sensor is small in comparison to the size usually considered with fountain codes. Second, WSNs mostly rely on multi-hop transmissions. It implies a non null transmission duration for the end-to-end acknowledgement of the reception. During this period of time, the source is still transmitting useless packets, creating a specific overhead we define as the overflow. This paper brings the overflow problem to light and analyses its impact on the network performance. Our work can be viewed as the networking counterpart of the results presented by Pakzad et al.at ISIT 2005 applied to WSNs.

“…However, redundancy of data sensing may be hard to achieve in some monitoring scenarios, as when camera-enabled sensors are deployed [25]. In a different perspective, fountain codes in wireless sensor networks can provide reliable transmissions providing some level of diversity in the transmission flow [26], for example, combining data packets.…”

Wireless sensor networks can provide valuable information for a lot of measurement, tracking, surveillance, automation, and general-purpose monitoring applications. Information as humidity, temperature, pressure, infrared images, and noises will be sensed and packetized for distribution over the network, but corruption during transmission may compromise the accuracy of the retrieved information and even put people in danger. In fact, the sensed data may have different relevancies for the applications, altering the impact of packet corruptions. We propose a relevance-based partially reliable transmission approach to provide data delivery with different reliability guaranties, exploiting the relevancies of transmitted data when choosing the proper error recovery service. In this context, some error scenarios are investigated, considering different configurations of error bursts. We expect that the proposed partially reliable transmission mechanism can save energy over the network while assuring acceptable quality for sensing monitoring.

In this paper, we propose a simple bidirectional transmission protocol using network coding and digital Fountain codes. In particular, in the proposed scheme, two sources use digital Fountain codes to transmit their message to each other with the help of relays. Then, relays use Fountain codes and network coding to forward the source messages to both sources. To evaluate performance of the proposed protocols, we present the average total throughput over Rayleigh fading channels via Various Monte-Carlo simulations. Results show that the proposed protocol outperforms the two-way relaying transmission protocol without using network coding technique at high SNR region. Recently, some published works related to the use of FCs in cooperative communication have been proposed [4][5][6][7] . Results in [4][5][6][7] presented that these models can enhance the system performances in terms of capacity, throughput and transmission time.
