Abstract

newline ABSTRACT newlineThe digital world is already transitioning from sensing things to smart objects, yet newlinesensing objects will inevitably be integrated into smart objects. When a well-organized newlinecommunication system is developed among the objects for prompt response to the real newlineworld environment, objects or things can become smarter. For an efficient newlinecommunication system via Wireless Local Area Network (WLAN) or Wireless Personal newlineArea Network (WPAN), a network must be constructed over these devices (WPAN). newlineWLAN has a low power requirement, a low cost, and a limited bandwidth. Wireless newlinepersonal area networks and wireless local area networks must adhere to IEEE newlinespecifications. newlineFor organized data transfer in MAC (Medium Access Control) for organized data newlinetransmission To enable low data speeds, low prices, and low energy consumption, IEEE newline802.15.4 is built on the MAC Sub-layer, the LLC (Logical Link Control), and the Service newlineSpecific Convergence Sub-layer. IEEE 802.15.4 implementation in WSN, which requires newlinemonitoring data by sensing and controlling by actuating, as well as reducing network newlinepower consumption to improve network life expectancy. newlineAccording to the IETF draught, the de-facto values of IEEE 802.15.4 do not newlinepermit real-time data transfer in the MAC Sub Layer since they are static values. It is a newlinetime series problem that Fuzzy and ANFIS can handle. newlineWireless Sensor Networks are Networks consisting of limitless modes newline(Things/Devices) with Low Cost, Minimum Power, Minimal-Memory, and newlineLimitedBandwidth Communication capabilities. This kind of Network over the Internet newlineleads to modernization, and Energy minimization is considered a promising factor in newlineWSN for limited power networks. This Minimization of Energy and reducing Delay so as newlineto intensify the network life-time is considered the main objective of the project. newlineAs per the IETF draft, De-facto IEEE 802.15.4 are not supportive in the real-time newlinecommunication as there are static values which is a research problem identified. It is a newlineTime-Series Problem tha
