Abstract
Bluetooth uses 2.4 GHz in ISM (industrial, scientific, and medical) band, which it shares with other wireless operating system technologies like ZigBee and WLAN. The Bluetooth core design comprises a low-energy version of a low-rate wireless personal area network and supports point-to-point or point-to-multipoint connections. The aim of the study is to develop a Bluetooth mesh flooding and to estimate packet delivery ratio in wireless sensor networks to model asynchronous transmissions including a visual representation of a mesh network, node-related statistics, and a packet delivery ratio (PDR). This work provides a platform for Bluetooth networking by analyzing the flooding of the network layers and configuring the architecture of a multi-node Bluetooth mesh. Five simulation scenarios have been presented to evaluate the network flooding performance. These scenarios have been performed over an area of 200×200 meters including 81 randomly distributed nodes including different Relay/End node configurations and source-destination linking between nodes. The results indicate that the proposed approach can create a pathway between the source node and destination node within a mesh network of randomly distributed End and Relay nodes using MATLAB environment. The results include probability calculation of getting a linking between two nodes based on Monte Carlo method, which was 88.7428 %, while the Average-hop-count linking between these nodes was 8. Based on the conducted survey, this is the first study to examine and demonstrate Bluetooth mesh flooding and estimate packet delivery ratio in wireless sensor networks
Highlights
It is essential to pay more attention to Bluetooth networking issues as it uses 2.4 GHz in ISM band applications, which it shares with other wireless operating system technologies like ZigBee and WLAN
Differential phase-shift keying (DPSK) and Gaussian frequency-shift keying (GFSK) are the modulation techniques used on the payload in the BR and enhanced data rate (EDR) modes, respectively with 1 M Symbol/s is the baud rate
The Bluetooth BR/EDR radio employs a Time-Division Duplex (TDD) system, which allows data to be transmitted in only one way at a time
Summary
It is essential to pay more attention to Bluetooth networking issues as it uses 2.4 GHz in ISM (industrial, scien- tific, and medical) band applications, which it shares with other wireless operating system technologies like ZigBee and WLAN. The Special Interest Group (SIG) defines two PHY modes in the Bluetooth core design [1]; the mandatory BR and the optional enhanced data rate (EDR). The Bluetooth BR/EDR radio uses a frequency hopping spread spectrum (FHSS) method with a hop rate of 1,600 hops per second. On 79 selected Bluetooth channels, the radio jumps in a pseudo-random manner. Each Bluetooth channel has a 1 MHz bandwidth. The Bluetooth BR/EDR radio employs a Time-Division Duplex (TDD) system, which allows data to be transmitted in only one way at a time. Bluetooth and WLAN radios coexist in the same physical environment and on the same device. The IEEE 802.15.2 Task Group [2] proposes adopting the AFH approach with Bluetooth and WLAN coexistence to reduce interference [3]
