The remote location of agricultural fields leads to the difficulty deploying Precision Agriculture (PA) systems as there is no Internet access in those areas. Therefore, use long-range wireless technologies such LoRa can provide connectivity rural areas and allow monitoring PA remotely. In this paper, a heterogeneous architecture protocol that allows communication with both WiFi LoRa, including...

In this paper, a salary-plus-bonus incentive mechanism is proposed to motivate WiFi Access Points (APs) to provide data offloading service for mobile network operators (MNOs). Under the proposed salary-plus-bonus scheme, WiFi APs are rewarded not only based on offloaded data volume but also based on the quality of their offloading service. The interactions between WiFi APs and the MNO under thi...

Densely deployed WiFi networks will play a crucial role in providing the capacity for next generation mobile internet. However, due to increasing interference, overlapped channels in WiFi networks and throughput efficiency degradation, densely deployed WiFi networks is not a guarantee to obtain higher throughput. An emergent challenge is how to efficiently utilize scarce spectrum resources, by ...

The IEEE 802.11 (WiFi) is now the de-facto standard for the overwhelming majority of Wireless Local Area Networks (WLANs). Up to now, many different 802.11 models, including channel models, stack models and traffic models, were proposed to estimate the protocol characteristics [1]. Almost all of them are based on the network simulation in MATLAB [2] , OPNET [3], ns-2 [4] or other packages. Unfo...

We present the DeepWiFi protocol, which hardens baseline WiFi (IEEE 802.11ac) with deep learning and sustains high throughput by mitigating out-of-network interference. is interoperable builds upon existing WiFi's PHY transceiver chain without changing MAC frame format. Users run for: i) RF front end processing; ii) spectrum sensing signal classification; iii) authentication; iv) channel select...

Wireless Heterogeneous Network (HetNet) with small cells presents a new backhauling challenge which differs from those of experienced by conventional macro-cells. In practice, the choice of backhaul technology for these small cells whether fiber, xDSL, point–to-point and point-to-multipoint wireless, or multi-hop/mesh networks, is often governed by availability and cost, and not by required cap...

Wide deployment of the 802.11g/n protocols for implementing next generation WLAN has encouraged research on the integration of these networks and GPS as a promising approach to enhance GPS for indoor positioning. WLAN, or WiFi, using the 802.11 standards, can be employed in several different ways as a complementary positioning technology for GPS navigation and the two can be used in an integrat...

 WiFi is a common communication interface for smart devices.  WiFi still has some perturbation such as: – Poor utilization of wireless channel. – Energy consumption during idle state. – Unfairness issue due to capture effect.

For the majority of applications that use positioning information, solutions from Global Navigation Satellite Systems (GNSS) can easily meet the accuracy, availability and reliability required. This assumes that the GNSS receiver is always operating in an environment that offers clear sky visibility. However, for a growing number of location based services and system, operation in urban or indo...
