Reliability Improved Cooperative Communication over Wireless Sensor Networks

Abstract

Abstract:With the development of smart devices and connection technologies, Wireless Sensor Networks (WSNs) are becoming increasingly intelligent. New or special functions can be obtained by receiving new versions of program codes to upgrade their software systems, forming the so-called smart Internet of Things (IoT). Due to the lossy property of wireless channels, data collection in WSNs still suffers from a long delay, high energy consumption, and many retransmissions. Thanks to wireless software-defined networks (WSDNs), software in sensors can now be updated to help them transmit data cooperatively, thereby achieving more reliable communication. In this paper, a Reliability Improved Cooperative Communication (RICC) data collection scheme is proposed to improve the reliability of random-network-coding-based cooperative communications in multi-hop relay WSNs without reducing the network lifetime. In WSNs, sensors in different positions can have different numbers of packets to handle, resulting in the unbalanced energy consumption of the network. In particular, nodes in non-hotspot areas have up to 90% of their original energy remaining when the network dies. To efficiently use the residual energy, in RICC, high data transmission power is adopted in non-hotspot areas to achieve a higher reliability at the cost of large energy consumption, and relatively low transmission power is adopted in hotspot areas to maintain the long network lifetime. Therefore, high reliability and a long network lifetime can be obtained simultaneously. The simulation results show that compared with other scheme, RICC can reduce the end-to-end Message Fail delivering Ratio (MFR) by 59.4%-62.8% under the same lifetime with a more balanced energy utilization.

Cooperative communications using relay nodes for next‐generation wireless networks with optimal selection techniques: A review

“…In case if the cooperative mode is not required during transmission of data, then User A transmits its own data in the second time frame, as a matter of fact, in both cases, spectrum efficiency increases . Moreover, in the coded cooperative relaying protocol, the reliability of the communication system increases with better utilization of the given spectrum .…”

“…To accomplish energy productive collaboration based correspondence, it can likewise coordinate with different conventions. In [18], proposed to get exceptional capacity by utilizing new form of codes to redesign programming, called shrewd Internet of things (IOT). Because of cruel channel qualities, information gathering is still issues in WSN because of long deferral, energy utilization and retransmission.…”

Multipath Cluster-based Hybrid MAC Protocol for Wireless Sensor Networks

“…One of the significant elements of an elegant infrastructure is the nodes of the sensor of the wireless, which also have an easy structure, of lesser price and also proper for a broad range of operation settings. Hence, they would finish the smart grid monitoring realization [37,38,39]. WSN (Wireless Sensor Networks) are frequently utilized for smart grids, monitoring the environment, operational surveillance, home and industrial automation [40,41,42], and also community systems, like networks of community mobile [43,44,45].…”
