Intelligent Sleeping Mechanism for wireless sensor networks

Abstract

In this paper, a Low-Energy Adaptive Clustering Hierarchy Centralized Sleeping Protocol (LEACH-CS) for wireless sensor networks has been proposed. LEACH-CS extends the lifetime of wireless sensor networks by proposing a mechanism that performs an intelligent choice of functioning nodes depending on the data sensed at the time being. If the data received from certain clusters appears insignificant in a period of time, these clusters are set to sleeping mode till the next data round. An algorithm named Intelligent Sleeping Mechanism (ISM) has been proposed for choice of nodes modes of functionality. When comparing LEACH-CS to the famous LEACH-C protocol through simulations, LEACH-CS succeeds in extending the lifetime of the network by on average 35% more than LEACH-C through network scaling and minimizing the end-to-end delay of data sending by an average 50% less than LEACH-C. LEACH-CS has been proposed for cultivation applications, where conditions may remain stable for a while and are not critical from one second to the other.
