“…In the world of the Internet, the Internet Protocol (IP) and the Transmission Control Protocol (TCP) are some of the most important protocols for data broadcast. Other protocols linked with these are the Post Office Protocol (POP), Simple Mail Transfer Protocol (SMTP), and Hypertext Transfer Protocol (HTTP) [12]. In communication both analog and digital are very important during file transfer and internet access.…”

Climate change, soil erosion, and degradation among others affect the growth and production of crops. Soil is suffering from intensive farming and unsustainable soil disturbance, leading to severe soil degradation. The Internet of Things (IoT) allows the monitoring of crucial environmental parameters such as soil nutrients, moisture, humidity, and temperature. A pre-understanding of these parameters allows agriculturists to use the optimum quantity of water and fertilizer for different types of soil. Soil fertility can be detected by using NPK sensors. The Internet of Things (IoT) brought a new face to the crop farming approach where conventional methods are automated and/or remotely controlled to improve crop farming. In this paper, a survey on IoT technologies for crop farming including sensors, communication, and network protocols in crop farming activities is considered. Additionally, applications of IoT technologies in soil management and monitoring, growth and yield estimation, and quality control mechanisms are presented.

“…ARQ and FEC are two main error control approaches often used. Generally speaking considering the way retransmission takes place, there are three types of ARQ protocols, namely, stop-and-wait (S-W), go-back-n , and selective repeat [1] [2].…”

“…There are two key error control strategies in WSN for maintaining reliable communication over noisy channels. The first one is Forward Error Correction (FEC) [1], which relies on transmission of redundant data to allow the receiver node to reconstruct the original messages. The second strategy is Automatic Repeat Request (ARQ) [2], in which high-rate detection codes are normally used and a transmission is requested if the received data is found to be erroneous.…”

Delay sensitive applications of Wireless Sensor Networks (WSNs) demand timely data delivery for fast identification of out-of-ordinary situations and fast and reliable delivery of notification and warning messages. Due to unreliable nature of WSNs, achieving real-time guarantees and providing reliable data are quite challenging. Reliable data dissemination is traditionally performed by applying error control protocols which are not suitable for time critical applications deployed in a packet burst loss WSN. In this paper, we propose READ+ which is an enhanced version of READ, i.e., a real time and energy efficient error controlling scheme to ensure reliability for delay constrained aggregated data over a bursty channel in a chainbased WSN. In READ+ link qualities are updated either locally by sensor nodes or globally by the Base Station (BS). The simulation results show READ+ performs better considering both hit ratio and energy efficiency compared with the XOR based Forward Error Correction (FEC) and the stop-and-wait (S-W) ARQ specially when duty cycling is low and when either average packet loss is low or packet TTL is short.

“…Reliable data dissemination is traditionally guaranteed by applying error control protocols. The main shortcoming of these approaches is that they very often introduce energy or/and delay overheads as they add redundancy to the packets (Forward Error Correction) or to the transmission (retransmission based approaches) [1].…”

Reliable and energy-efficient data dissemination is an important challenge particularly in multi-hop Wireless Sensor Networks (WSNs). Although clustering is considered as one of the promising techniques for energy aware data dissemination, majority of research in this area assume a reliable network, in which no packet is lost due to low link quality. In this paper we propose REC+, a Reliable and Energy-efficient Chain-cluster based routing protocol, which aims to achieve the maximum reliability in a multi-hop network by finding the best place for the Cluster Head (CH) and the proper shape/size of the clusters without the need of using any error controlling approaches that can be quite expensive in terms of computation and communication overhead. Most importantly, REC+ relaxes some strong assumptions that other cluster-based routing algorithms rely on, which make them inapplicable for real WSNs. To the best of our knowledge, REC+ is the first cluster based routing algorithm that considers energy efficiency, transmission reliability and intra-cluster delay all together to construct clusters and select proper CHs in WSNs. In the simulation, we show superiority of our approach over three others in terms of the product of energy consumption and delay.
