“…The interference effect of WiFi entertainment system on WSN is not included, but rather multiple access points are offered as a solution for reliability increase. In other works from Gonga [4] and Du [5], WiFi coexistence of TSCH based WSN is investigated in an office environment in order to extract the effect of interference and frequency diversity. The first conclusion was that packet drop rate was not directly correlated to WiFi interference due to uncontrolled environment.…”

Abstract-In this paper we present the effects of Wi-Fi interference on a Wireless Sensor Network (WSN) in an aircraft. We use Time-Slotted Channel Hopping (IEEE 802.15.4e) as Link layer in the WSN network. We conduct measurements in an environment realistically representing an aircraft cabin. We provide the resulting application failure and packet drop rates with and without interference, for an exemplary deadline critical application. In order to outline the importance of hopping against interference in a controlled environment, we compare the results of individual channels, full channel hopping and clear channel hopping, where the TSCH only hops over channels free from WiFi interference. Results open further discussions for more sophisticated Link layer implementations resulting in increased reliability such as optimization of frequency allocation depending on the application deadline.

“…Because 6LoWPAN is a compact version of IPv6 optimized for low power wireless transmission, relatively simple adaptation procedures are used to switch between the ordinary IPv6 protocol and 6LoWPAN. Unlike the previous approach, the IP nature of 6LoWPAN ensures the entire network is a seamless integration of things and the Internet, and this practice has been employed in studies such as [3,115] to form IP-based wireless sensor networks. Although 6LoWPAN was designed for wireless sensor networks (WSNs), the idea is not exclusive to specific applications and can be extended to any power-constrained IoT devices.…”

“…Inspired by the TDMA-based channel-hopping technique described in [49,75,76], the work in [3,77] were able to conveniently coordinate the cooperative activity by assigning timeslots to tasks, such as suspending normal communication, in order to create quiet periods during which the channel noise floor can be sensed without interference among fellow motes.…”

“…Whilst the proliferation of wireless communication has been paving the way for the emergence of IoT, the growing quantities of things sharing the limited spectral space place unique doubts for limited resources. As a result, devices with relatively low transmission power may suffer from reduced chance of communication and increased risk of interference, particularly at sites where objects are co-located with high density [3].…”

Abstract:The vision for the Internet of Things (IoT) demands that material objects acquire communications and computation capabilities and become able to automatically identify themselves through standard protocols and open systems, using the Internet as their foundation. Yet, several challenges still must be addressed for this vision to become a reality. A core ingredient in such development is the ability of heterogeneous devices to communicate adaptively so as to make the best of limited spectrum availability and cope with competition which is inevitable as more and more objects connect to the system. This survey provides an overview of current developments in this area, placing emphasis on wireless sensor networks that can provide IoT capabilities for material objects and techniques that can be used in the context of systems employing low-power versions of the Internet Protocol (IP) stack. The survey introduces a conceptual model that facilitates the identification of opportunities for adaptation in each layer of the network stack. After a detailed discussion of specific approaches applicable to particular layers, we consider how sharing information across layers can facilitate further adaptation. We conclude with a discussion of future research directions.

Abstract-Time-Slotted Channel hopping (TSCH) that was introduced in IEEE802.15.4e is a promising technique to offer deterministic data deliveries in Wireless Sensor Networks (WSN). Its main strength lies in using multiple channels for the transmissions, using frequency hopping method. However, it takes more time for initializing the network, as beacons have to be released on multiple frequencies and scanning needs to be carried out by the devices in all those frequencies for joining the network. In this work, a simulation study is carried out to investigate the effect of these delays for different types of multihop networks. The benefit of introducing multiple coordinators in reducing these time delays is also studied. It is found that the delays are increasing linearly with the number of hops in the network and adding an additional coordinator can bring down the initialization time by half.
