In this paper, an Efficient Retransmission Random Access Protocol (ERRAP) is designed that combines scheme of collision avoidance and energy management for low-cost, short-range wireless radios and low-energy sensor nodes applications. This protocol focuses on efficient Media Access Control (MAC) schemes to provide autonomous Quality of Service (QoS) to the sensor nodes in one-hop QoS retransmission group in WSNs where the source nodes do not have receiver circuits. These sensor nodes can only transmit data to a destination node, but cannot receive acknowledgement or control signals from the destination node. The proposed scheme ERRAP provides QoS to the nodes which work independently on predefined time by allowing them to transmit each packet an optimal number of times within a given period. Our simulation results demonstrate the superiority of ERRAP scheme which increases the delivery probability and reduces the energy consumption. IntroductionWireless Sensor Networks (WSNs) consist of a large number of distributed nodes, that combine automated sensing, embedded computing and wireless components into tiny embedded devices. WSNs gather information or detect special events and communicate in a wireless fashion. WSNs provide a wide range of potential

“…MORE [9] is an opportunistic routing scheme with network coding enhancement, and it shows that random linear network coding is useful for the retransmission of multicast data where individual retransmission for disparate destinations is inefficient. Similar to it, BENEFIT [11] introduces an efficient network coding-based retransmission algorithm for multicasting, and [12] applies it to IEEE 802.16 WiMAX [20]. Efficient Retransmission (ER) extends the idea to multiple-destination unicast case [10].…”

We present SYNC, a physical layer transmission scheme that drastically reduces the cost of retransmission by introducing network coding concepts to symbol level operation. It piggybacks a new packet on each retransmitted packet, and exploits the previously received packet (possibly with error) at the receiver to recover both the retransmitted packet and the piggybacked packet. The piggybacking is achieved through higher modulation, but it does not decrease the decodability of the mixed packets owing to the previously received packet at the receiver, which can be analytically shown. SYNC works independently of other PHY level performance boosting schemes such as channel coding and spatial diversity. The proof-of-concept SYNC prototype has been implemented on a software defined radio (SDR) platform. The measurement data shows that under the same channel condition SYNC achieves 110 percent and 42 percent median throughput gain over traditional retransmission and SOFT, respectively. We also show that SYNC can be used proactively where the feedback as to the success of the previous transmission is not available, such as in broadcast.

“…In addition to protocol designs, recent works [2]- [8] suggest that network coding has immense potential as a mean to minimize retransmissions and improve reliability of lossy wireless networks. It has also been proposed for the IEEE 802.16n MAC standard.…”

In the literature, cooperative relaying and network coding have been used separately in improving performance of wireless MAC protocols. In this paper, we propose a novel scheme that combines both cooperative relaying and network coding for further performance improvement. The proposed scheme considers two challenges of network-coded cooperative MAC operating in a realistic wireless network. First, links in realistic networks inherently operate with different data rates due to varying channel conditions and distances between the nodes. Existing works do not consider this issue and consequently the coding advantage is not fully harnessed. In our proposed scheme, we integrate both network coding and multi-rate issues as a single optimization problem. Second, network coding used in existing works require costly and reliable feedback in order to harness the gain. Since realistic links are unreliable in nature, our proposed scheme uses a cyclic coding method instead of the traditional XOR coding. Our results show that the proposed scheme can achieve a gain that is two times greater than a non-cooperative scheme.
