Energy Efficient Scheduling techniques for Wireless Sensor Networks

Abstract

Scheduled Data Transfer within the sensor nodes has become paramount importance in recent years of Sensor Field. Network Lifetime depends on the battery power of the sensor nodes. Reducing such consumption is proven to be a highly effective task of saving electricity that runs for the network. A Connected Dominating Tree (CDT) is constructed as a sub-network of the Wireless Sensor Network using Minimum Connected Dominating Set (MCDS) concept. The Optimal Wake-up Scheduling of Nodes (OWSN) algorithm is used to reduce the total energy consumption by decreasing the forwarder or connector nodes. Here the lifetime is prolonged by making the sensor nodes toggle their states from awake to sleep and vice-versa. Herewith the nodes are made to get synchronized through scheduling and increase the active delivery ratio for effective data transmitting. The Simulation analysis of the work proves that by transferring the data in the most scheduled way, the overall energy consumption is reduced and the performance of the sensor network is increased.
