scholarly journals Energy Efficient QoS guaranteed Cross Layer Solution (EEQCL) for Mesh Backbone IOT Networks

IOT enables devices to be managed and monitored anywhere from internet. With IOT gaining popularity, billions of devices are connected to internet and they are being used for many applications like home automation, public safety, smart city, traffic monitoring etc. IOT interconnectivity to internet based on mesh network is the most used topology due to effectiveness in scalability and reliability. The mesh network must be optimized in terms of QOS, energy efficiency for the case of nature of traffic from IOT devices. Towards this end, this work proposes an energy efficient QOS guaranteed cross layer solution for mesh backbone based IOT network. The proposed cross layer solution applies changes at Application, session, network layer to achiness a better QOS and energy efficiency than existing solutions discussed in literature.

: IoT becomes more complicated due to its large size. The existing techniques of Wireless Sensor Networks (WSN) are not useful directly to the IoT. That’s why the using the energy efficient schemes for the IoT is a challenging issue. Due to battery constrained IoT devices, energy efficiency is of greatest importance. This paper gives overview and broad survey on IoT, WSN in IoT, Challenges in IoT and WSN, energy conserving issues and solutions and different Node Deployment patterns. For green IoT, this paper addresses energy competence issues by proposing an energy efficient heuristic for a regular and particular deployment scheme. QC-MCSC heuristic is implemented for Strip Based Deployment Pattern and analyzed in terms of Energy Efficiency and Life Time of a sensor on Energy Latency Density Design Space, a topology management application that is power efficient. QC-MCSC for Strip based deployment pattern and for random deployment pattern are compared.

Energy efficiency is a major concern for mesh nodes with limited power supply. So STDMA(spatial time division multiple access) is applied to reduce node’s power consumption in mesh networks. However, the energy cost was still high for solar panel applying with STDMA, due to the fixed slots and numerous start times of nodes. A VF-STDMA(variable frame in STDMA) is proposed based on STDMA protocol. The VF-STDMA dynamically changes the frame size and assigns timeslots to each link according to the network data flows. The start times are reduced by recombining slots. Finally, the optimum routing is obtained through a cross-layer mechanism covering physical layer, MAC layer and network layer. The results show that the algorithms improve energy efficiency as well as decrease energy consumption of solar panel.

In recent years, a lot of IoT devices, wireless sensors, and smart things contain information that must be transmitted to the server for further processing. Due to the distance between devices, battery power, and the possibility of sudden device failure, the network that connects the devices must be scalable, energy efficient, and flexible. Particular attention must be paid to the protection of the transmitted data. The Bluetooth mesh was chosen as such a network. This network is built on top of Bluetooth Low-Energy devices, which are widespread in the market and whose radio modules are available from several manufacturers. This paper presents an overview of security mechanisms for the Bluetooth mesh network. This network provides encryption at two layers: network and upper transport layers, which increases the level of data security. The network uses sequence numbers for each message to protect against replay attacks. The introduction of devices into the network is provided with an encryption key, and the out-of-band (OOB) mechanism is also supported. At the moment, a comparison has been made between attacks and defense mechanisms that overlap these attacks. The article also suggested ways to improve network resiliency.

Abstract Background: The Internet of Things (IoT) enables the development of innovative applications in various domains such as healthcare, transportation, and Industry 4.0. Publish-subscribe systems enable IoT devices to communicate with the cloud platform. However, IoT applications need context-aware messages to translate the data into contextual information, allowing the applications to act cognitively. Besides, end-to-end security of publish-subscribe messages on both ends (devices and cloud) is essential. However, achieving security on constrained IoT devices with memory, payload, and energy restrictions is a challenge. Contribution: Messages in IoT need to achieve both energy efficiency and secure delivery. Thus, the main contribution of this paper refers to a performance evaluation of a message structure that standardizes the publish-subscribe topic and payload used by the cloud platform and the IoT devices. We also propose a standardization for the topic and payload for publish-subscribe systems. Conclusion: The messages promote energy efficiency, enabling ultra-low-power and high-capacity devices and reducing the bytes transmitted in the IoT domain. The performance evaluation demonstrates that publish-subscribe systems (namely, AMQP, DDS, and MQTT) can use our proposed energy-efficient message structure on IoT. Additionally, the message system provides end-to-end confidentiality, integrity, and authenticity between IoT devices and the cloud platform.
