“…Also, because the existing routing protocols require more processing for multi-hop transmission in the network layer, they consume more energy. To address this problem, various approaches have been developed to maintain the energy efficiency at every layer of the protocol stack by offering new algorithms and protocols [ 6 , 7 , 8 , 9 ]. However, the separation of layers has become an obstacle to improving the network performance.…”

Abstract:The IEEE 802.15.4 standard is widely recognized as one of the most successful enabling technologies for short range low rate wireless communications and it is used in IoT applications. It covers all the details related to the MAC and PHY layers of the IoT protocol stack. Due to the nature of IoT, the wireless sensor networks are autonomously self-organized networks without infrastructure support. One of the issues in IoT is the network scalability. To address this issue, it is necessary to support the multi-hop topology. The IEEE 802.15.4 network can support a star, peer-to-peer, or cluster-tree topology. One of the IEEE 802.15.4 topologies suited for the high predictability of performance guarantees and energy efficient behavior is a cluster-tree topology where sensor nodes can switch off their transceivers and go into a sleep state to save energy. However, the IEEE 802.15.4 cluster-tree topology may not be able to provide sufficient bandwidth for the increased traffic load and the additional information may not be delivered successfully. The common drawback of the existing approaches is that they do not address the poor bandwidth utilization problem in IEEE 802.15.4 cluster-tree networks, so it is difficult to increase the network performance. Therefore, to solve this problem in this paper we study a relay transmission protocol based on the standard protocol in the IEEE 802.15.4 MAC. In the proposed scheme, the coordinators can relay data frames to their parent devices or their children devices without contention and can provide bandwidth for the increased traffic load or the number of devices. We also evaluate the performance of the proposed scheme through simulation. The simulation results demonstrate that the proposed scheme can improve the reliability, the end-to-end delay, and the energy consumption.

IEEE 802.15.4 is a very popular standard for low rate wireless personal area network (LR-WPAN) due to its low energy consumption and different short range applications. Packet error rate (PER) of 802.15.4 PHY layer in the presence of a third node as a wireless relay between source and destination node is analyzed. PER is obtained from the bit error rate (BER) and the BER is obtained from signal to noise interference ratio. PER increases the no. of retransmission as well as energy consumption. The main focus of this paper is to investigate that under which relaying strategy PER is less so the energy consumption in PHY layer can be reduced. The simulation results are shown to validate the analytical formulations.Index Terms-LR-WPAN,IEEE 802.15.4, Relay, Amplify-andforward (AF), Decode-and-forward (DF), Signal to noise ratio (SNR), Packer error rate (PER), Payload Length.
