The ubiquity of wireless technologies in the Internet of Things (IoT) concept enforces utilization of power-optimized wireless techniques. Furthermore, a specially tailored mesh-routing algorithm is required in order to achieve battery longevity and node accessibility. In the paper, we propose an improved BLE (Bluetooth Low Energy) mesh-routing algorithm for an IoT Smart Home application. The proposed algorithm is based on a time-slotted medium-access scheme, which enables communication nodes to sleep and/or exchange information. In order to achieve compatibility with any BLE-enabled device, such as mobile phones/tablets, routing and data information is transmitted via Eddystone beacons. Performance analysis of the proposed BLE mesh-routing algorithm is carried out using an OMNeT++ discrete simulation environment and Mixim framework. Validation of the proposed algorithm is completed on the basis of measurements from a real-life test network. The results show that the proposed algorithm is suitable for the IoT applications where the energy efficiency of the communication nodes is a key priority and propagation delays are not critical.

Recent advances in the development of wearable sensors and smartphones open up opportunities for executing computing operations on the devices instead of using them for streaming raw d ...

This paper presents the discrete-event simulator of the low-voltage broadband power line communication (BPLC) access network in accordance with the IEEE P1901 standard. The proposed simulator enables the cross-layer simulation of the physical (PHY) and medium access control (MAC) layer. The performance of the digital communication techniques at the physical layer and the characteristics of the shared medium are integrated at the MAC layer through the probability of the bit error. The proposed simulator was applied in order to estimate the throughput in the simple BPLC network. For the selected set of parameters at the MAC and PHY layer in the test network, the simulator recorded average download throughput of 900kbps, registration time of 36ms and packet delivery ratio of for 0.98 between each station and the HE.
