“…Discussing these difficulties allows service suppliers and software programmers to effectively execute their services. The IoT's availability must be realized at the hardware Running time Shen et al (2017) Energy dissipation, average data transmission and number of alive nodes Ugrenovic and Gardasevic (2015) Structure of packets and flows Amin et al (2016) Storage cost, computation cost and communication cost Liu and Ravishankar (2011) Number of nodes alive and network lifetime Chao et al (2011) Evaluation time and number of H2M terminals Faisal et al (2013) Stability period, network lifetime and throughput Sun et al (2019) Computation time, energy consumption Li et al (2017) Failure probability Razaque et al (2016) Energy consumption, computational cost Sahraoui and Bilami (2014) Energy efficiency Lv et al (2018) Energy efficiency Tripathi et al (2013) Number of nodes, network lifetime and energy dissipation Debroy et al (2019) Average number of channel switches and hops, end-to-end data rate Behera et al (2019) Average residual energy, network stability, network lifetime and throughput Tong and Tang (2010) System lifetime, energy dissipation and number of cluster heads Naguib et al (2019) Energy consumption, average end-to-end delay, throughput and network lifetime Goudos et al (2019) Input power and objective function value Tian and Hou (2010) Average delay, packet delivery fraction and routing bits Rajandekar and Sikdar (2018) Number of M2M packets and average delay in Wi-Fi Parne et al (2018) Communication overhead Kamble and Jadhav (2018) Average throughput, average delay and average energy consumption Isa et al (2012) System patching Modiri et al (2018) Communication overhead and computational overhead TRENTIN et al (2018) Communication efficiency Saad et al (2018) Throughput and delay (continued) and software level to offer every client with services anywhere and at any time. Reliability corresponds to the system's smooth operation relying on its specification that is intended to improve the achievement rate of IoT in its service delivery.…”
