In this paper hexagonal heterogeneous broad transmission distance protocol (HEXA-HTBTDP) is introduced and scalability analysis is performed in the context of internet-of-things (IoTs). A two-dimensional (2-D) hexagonal feld is taken for the random deployment of sensor nodes which will be benefcial in the recently emerging integrated wireless sensor networkinternet-of-things (WSN-IoTs). This technology opens new horizons for the cellular and mobile communications. With the growing demand for an efcient utilization of resources at present, it is a challenging task to develop clustering protocols which support wirelessly connected heterogeneous sensor nodes. They exist either independently or embedded within devices in the network. With a common objective of achieving energy efciency, reliable communication, connectivity and coverage of network feld, scalability is analyzed by varying the number of nodes and their initial energies. Two-level energy heterogeneity is adopted in the form of normal and advanced nodes. HEXA-HTBTDP is compared with hexagonal feld versions of classical protocols viz. hexagonal stable election protocol (HEXA-SEP) and hexagonal energy efcient heterogeneous clustered scheme (HEXA-EEHC). Benchmarking parameters used for the comparison of results are stability period, network lifetime, instability period, residual energy and energy variance. The hexagonal feld will expand the current scenario of clustering for the achievement of quality of service (QoS) and quality of user experience (QoE) in real time WSN-IoT systems
