Recently, new breakthroughs are made which are 3rd generation of Energy Harvesting of wireless sensor technology. The Bluetooth Low Energy (BLE) technology reduces power consumption compares with traditional protocol. In the present This new protocol is rapidly and broadly adopting in wearable devices. And its advantages of low power consumption and connectivity with Smart devices , the wireless market is also demanding to adopt this protocol. The new trend is going with combination of BLE and Energy Harvesting.
It also made breakthrough in harvester which is perovskite-solar-cell. This new solar cell can generate electricity with high efficiency and can manufacture with low cost. It’s still under research stage but is gathering high interest from energy generating Industry and solar cell industry. The battery less wireless sensor combined of perovskite solar cell and BLE is a technology of upcoming wireless sensor market Cypress is providing 2 types of (PMIC) Power Management IC products as the core of Energy generating.
Internet Protocol (IP)
(Frontoni, 2013.)Internet Protocol (IP) is the primary network protocol used on the Internet, developed in 1970s. IP is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. The two versions of Internet Protocol (IP) are in use: IPv4 and IPv6. Each version defines an IP address differently. Because of its prevalence, the generic term IP address typically still refers to the addresses defined by IPv4. There are five classes of available IP ranges in IPv4: Class A, Class B, Class C, Class D and Class E, while only A, B, and C are commonly used. The actual protocol provides for 4.3 billion IPv4 addresses while the IPv6 will significantly augment the availability to 85,000 trillion addresses .IPv6 is the 21st century Internet Protocol. This supports around for 2128 addresses.
Energy Harvesting (EH) technologies could be a solution for many power supply related issues especially in IoT ; wireless projects. EH technology is not only green and clean but decrease a lot of hassle ; also price considerations. We hope to see our future in sight smart cities and smart wearable technologies and industrial technologies to be equipped with EH sensors and power modules with generating power by own.

Recently, more generalized and object-oriented system dynamics simulation models have been developed. As one of the earliest applications, Palmer et al. (1993) tailored a dynamic simulation software application to represent the Portland water supply system. Other applications include river basin planning (Palmer et al. 2000), long-term water resource planning and policy analysis (Simonovic et al. 1997; Simonovic and Fahmy 1999), reservoir operation (Ahmad and Simonovic 2000), sustainability of a water resource system, and water supply planning and management (Nandalal and Simonovic 2003). System dynamics modeling was also used to model sea level rise in a coastal area by Ruth and Pieper (1994).

Simonovic and Bender (1996) applied a dynamic simulation approach to a collaborative planning-support system by adding environmental issues, e.g. fish habitat, to hydroelectric power generation. Passell et al. (2002) presented a computerized dynamic model to simulate the hydrology, ecology, demography and economy in the Middle Rio Grande Basin using the commercially-available application, Powersim Studio. Water sustainability and groundwater storage in San Pedro River Basin, AZ was evaluated by Sumer et al. (2004).
