Implementation of Earliest Deadline First Algorithm for Wireless Sensor Network
Main Article Content
Abstract
This paper presents the implementation of an earliest deadline first (EDF) scheduling mechanism for Wireless Sensor Network (WSN). In this paper we are monitoring and scheduling the sensor values in real time by embedding wireless sensor nodes. We use the LPC2148 ARM7TMDI based microcontroller which is used as core control module and design the overall structure of the system according to the basic need of wireless sensor network. We design the hardware system structure and software system structure where we implement EDF algorithm for scheduling aperiodic task of the WSN in a real time way.
Keywords: Wireless Sensor Network, EDF algorithm, Rate monotonic, Deadline Monotonic.
