This work presents a review starting from the 'Smart Dust' vi-sion, describing WSN platforms and components. By reviewing the past and present of WSN systems and their development, significant conclusions can be drawn. The realism of the deployments has exposed substantial and serious barriers to initial application ideas, to interdisciplinary research and thus to the adoption of WSN systems. While there has been a lot of progress in theoretical work and system optimizations, actual deployments have been non-or. Since the vision of 'Smart Dust', the field has largely progressed: Miniaturization, integration and advances in MEMS technology have significantly stimulated research efforts. Wireless Sensor Networks (WSNs) have been promised a bright future and economic potential. Our simulation results show that these algorithms along with an appropriate routing protocol can prolong the network lifetime by up to 47.45%.

This motivated us to work on an effective node placement strategy for a BNC, within a WBAN and thus we propose three different BNC placement algorithms considering different features of available energy efficient routing protocols in a WBAN. Our initial work shows that the variation in the placement of a BNC within a WBAN could significantly vary the overall network lifetime. In this work, we exhibit that a routing protocol together with an effective body node coordinator (BNC) deployment strategy can influence the network lifetime eminently. Therefore, routing protocols can play a key role towards making such networks energy efficient.

In a WBAN, network longevity is a major challenge due to the limitation of the availability of energy supply in body nodes. They are used to support a variety of personalized, advanced, and integrated applications in the field of medical, fitness, sports, military, and consumer electronics. Wireless body area networks (WBANs) are intelligent wireless monitoring systems, consisting of wearable, and implantable computing devices on or in the human body. The 11th Ethnic Minority Games held in 2019 will have 18 competitions, 17 individual events, 131 small events, and 55 ethnic minorities that participated in the joint participation of more than 7000 athletes participating in traditional sports of all nationalities and are the best inheritance and development of national sports. Experimental results show that in recent years, all ethnic groups have attached great importance to ethnic sports. The object proposes a national automated monitoring test, which uses several small sensors in the wireless sensor network to transmit information to monitor many real conditions in the human body during multisport, so as to find out that the national sports exercise is in real life. Based on the use of wireless sensor networks, this paper monitors the traditional national sports activities, provides real-time feedback on the actual human body conditions in different sports, and finds out the pros and cons of traditional sports and makes improvements. Ethnic sports are various ethnic sports that have gradually evolved into various popular sports in the long-term life experience, according to different living habits and residential areas, in the hunting activities of similar sports in the past.
