Energy Efficient Scalability of Heterogeneous Broad Transmission Distance Protocol (HT-BTDP) in WSN for Internet-of-Things

摘要

Wireless Sensor Networks (WSNs) are the collection of sensor nodes networked together to sense and gather data continuously or periodically. With the evolvement of latest global web technologies such as Internet-of-Things (IoT), Device-to-Device and Machine-to-Machine communication has opened new doors for Wireless Sensor Network applications. Heterogeneity in terms of energy in the devices independent or embedded is an inherent property of WSNs for internet-of-things. Dissimilar energy consumption of sensor nodes has become a crucial factor for the designing and development of clustering protocols. Stability period and network lifetime are the basic parameters for the realization of network from energy balancing point of view. Scalability in the network with variant number of nodes as well as different values of energies has allowed analysis of stability period, network lifetime and also sub-periods of lifetime for better connectivity, coverage and efficient communication in the above mentioned web applications. Periodic assessment of sub periods of lifetime for event based dynamic monitoring of the objects in internet-of-things will prove advantageous in the coming decades. A protocol based on broad and crossover transmission distance for heterogeneous wireless sensor network system is proposed here. This approach of Heterogeneous Broad Transmission Distance Protocol (HT-BTDP) with scalability is put forward for field-specific as well as event based applications of WSNs in IoT. Performance parameters for evaluation are alive node metrics depicting death of nodes as first, quarter, half, third quarter and last ones, which outperform the previous existing heterogeneous protocols.
