A Survey on Node Scheduling Methods for Wireless Sensor Networks

Abstract: The wireless sensor networks (WSN) is a combination of a large number of low-power, short-lived, unreliable sensors. The main challenge of wireless sensor network is to obtain long system lifetime. Many node scheduling algorithms are used to solve this problem. This methods can be divided into the following two major categories: first is round-based node scheduling and second is group-based node scheduling. In this paper many node scheduling algorithm like AFAP, RSGC, Tree-Based distributed wake-up scheduling and Clique based node scheduling Algorithm are analysed.
