A distributed processing environment consists of one or more applications spread over several computers. These computers may be geographically separated from one another. The applications may be executed on different platforms using different operating systems and telecommunication protocols. In short, a distributed operating environment offers a variety of information system solutions regardless of the location of the user, user’s operating system or the equipment using by user. Performance enhancement of the distributed networks is a major and challenging problem for the researchers. In this paper, algorithm designed, have to allocate m tasks to n processors (m>n) in the environment of distributed processing. These m tasks are to be assigned on the n processors of system through Greedy algorithm of task scheduling. The starting time and finishing time of the processing of a task is considered and denoted by Si and Fi where i= 1, 2, 3, 4, 5…… m. In order to evaluate the optimal time, present algorithm obtains the set of assigned and on assigned tasks. Based on these sets allocation has been made. The method is presented into algorithmic form and several sets of input data have been implemented to test the effectiveness of the algorithm.

The industrial IoT marching towards the digital twin and the broad spectrum of applications need the specialized low power protocols for communication and data transfer. This chapter provides a comprehensive discussion on the challenges, opportunities, use cases, platforms, and protocols for the deployment of low power protocols in the context of IoT applications. Moreover, discussion extends to the various custom techniques for energy saving in the communication of sensors to hardware, hardware to Cloud, and deferred data pushing in edge computing. The traditional wireless data transfer and communication protocols are suitable in case of the hardware platforms connected with seamless power supply. However, there is need of low power protocols 6LoWPAN, LoRaWAN, Sub 1, ZigBee, BLE, NFC, and other telecommunication protocols across several IoT applications. The SBCs and micro-controllers are not always equipped with these protocol-enabled hardware. This chapter addresses the suitable hardware and combination with low energy options as per the budget, range, and specifications.
