WPAN using IEEE 802.15.4 protcol operated in non beaconing mode an attempt has made to find out the most significant factor of defacto parameters of IEEE 802.15.4 to enhance the performance by minimizing energy consumption and to enhance the network lifetime of the Wireless Personal Area Networks(WPAN). The factors include Buffer size, Beacon Interval, Back-off-transmission has an ideal impact on QoS metrics in IEEE 802.15.4 protocol. A Design of experiments have been simulated to an optimum level using the taguchi approach. The experimental results from the taguchi approach reveales that Back-of-transmission as the most significant factor for IEEE 802.15.4 in minimizing the power consumption in the WPAN. 08 30 2021 143 147 CC BY-NC-ND 4.0 10.35940/BEIESP.CrossMarkPolicy www.ijitee.org true 10.35940/ijitee.J9416.08101021 https://www.ijitee.org/wp-content/uploads/papers/v10i10/J941608101021.pdf Department of Information System, College of Computer and Information Sciences, Imam Muhammad Ibn Saud Islamic University, Riyadh, Saudi Arabia. Waleed Rashideh Blockchain is an innovative technology, where in the hospitality and leisure industry, travelers can obtain their tourism products and services through an intermediation between travelers and service providers that causes many different problems (e.g. inefficient payment system, extra cost, etc.). The operative effect of blockchain on the hospitality and leisure industry is based on removing the intermediary from the supply chain. Blockchain capabilities are determined according to a number of massive industries, including financial sectors. Such organisations generate various methods in order to simplify trading for smaller and medium sizes of industries. The networks of the tourism value are based on power dependencies’ relationships in such a way many expert staff members have acquired additional values that are taken from their partnerships. The structure of a market can be improved based on the value, which relates to different online travel agencies via converting power from suppliers to consumers. The assessment demonstrates that the blockchain technology represents an effective technology that removes mediators, which are originally sourced from the supply chain. This technology does not allow any mediators to gain entry along towards the tourism industry, and by eliminating the market’s power. 08 30 2021 148 151 CC BY-NC-ND 4.0 10.35940/BEIESP.CrossMarkPolicy www.ijitee.org true 10.35940/ijitee.J9441.08101021 https://www.ijitee.org/wp-content/uploads/papers/v10i10/J944108101021.pdf
