“…This strategy decreases the communication overhead and system cost. The selection of the HAP used to communicate with the satellite is an important issue and techniques have been proposed for this [44,45]. The communication between sensors, RFID networks, and mobile ad hoc networks is possible using Internet or satellite/HAP networks as transmission mediums.…”

A dual coverage system for Internet of Things (IoT) environments is introduced. This system is used to connect IoT nodes regardless of their locations. The proposed system has three different architectures, which are based on satellites and High Altitude Platforms (HAPs). In case of Internet coverage problems, the Internet coverage will be replaced with the Satellite/HAP network coverage under specific restrictions such as loss and delay. According to IoT requirements, the proposed architectures should include multiple levels of satellites or HAPs, or a combination of both, to cover the global Internet things. It was shown that the Satellite/HAP/HAP/Things architecture provides the largest coverage area. A network simulation package, NS2, was used to test the performance of the proposed multilevel architectures. The results indicated that the HAP/HAP/Things architecture has the best end-to-end delay, packet loss, throughput, energy consumption, and handover.

“…In order to assess the efficiency of a WSN, two parameters have been defined: energy consumption over the lifetime of the system as well as the network throughput [6]. Throughput is a metric to evaluate the efficiency of the wireless standard deployed, because it takes into account the effect of collisions as well as retransmissions triggered by either interference or collisions [6]. Throughput can be expressed as the amount of data sent successfully over the channel by every node per transmission time [6].…”

Throughput can be expressed as the amount of data sent successfully over the channel by every node per transmission time [6]. In WSNs, due to sharing of the wireless channel and the open access to the wireless medium, the medium is prone to interference.…”

This paper proposes a methodology for calculating the energy consumed by a Wireless Sensor Network as well as its throughput under the effect of a jamming node modelling interference to account for collisions and retransmissions. Accordingly, the proposed methodology takes into consideration retransmissions and data dropped due to interference and collisions simultaneously. Simulations are conducted using OPNET to model various scenarios utilizing off-the-shelf wireless communication standards, namely ZigBee, Wi-Fi and Low Power Wi-Fi. A figure of merit is developed to offer more representative results for applications with different requirements. In achieving different requirements for a given application, there is a clear trade-off between energy consumption and throughput.
