Abstract
In a wireless network, the battery power decides the operation duration of a Wireless Sensor Network (WSN). Therefore, it is critical how to effectively manage the power of a wireless sensor. We propose a ‘Dynamic Frequency and Power Management Microcontroller for Wireless Sensor Network’ to solve this problem.There are three main characters of our microcontroller:1. Dynamic change of operating frequency according to different constraints.2. Provide the user the corresponding instructions to manage the power.3. By giving instructions, our microcontroller is a customized one. (The user can modify the parameters of the microcontroller by giving instructions so that it can be used in various applications.There are three main contents of our microcontroller:1. For users: We provide a easy understood instruction set (We provide a set of simple and clear instructions.) The users can use these instructions to change the operation frequency when the microcontroller is in operation. The users can also modify the parameters of power management mechanism to suit different power saving algorithms.2. For battery power: Different level of battery power has its corresponding operating frequency. The operating frequency corresponds to different battery power outputs.3. For the network: The operating frequency automatically changes according to various levels of activeness. The operating frequency automatically changes according to the level of activeness of the network.
