Improving the lifetime of wsn usingthe ch and th selection algorithmwith novel secured algorithm forreliable data communication

Abstract

The problem of increasing power consumption of processingelement is a critical issue in he designing of WSN applications. Reducing thepower consumption and increasing the network lifetime of the WSN becomesimperative while posing a design problem, especially if the Sensor nodes areoperated with restricted energy. The power consumption problem isconsidered to be mainly caused by a cumulative factor. In this process, theusers requiregreater functionality, increased processing, long-life battery, andcompact size. More importantly, these user requirements have to be satisfiedwithout increasing the cost of the (processor/unit).At the outset, to address this issue, a new framework for Energyconsumption system was developed in this framework. It consisted threesubsystems which are cluster formation and transmission head selection subsystem, Node scheduling sub system, Data encryption subsystem. The systemwas designed with an objective of introducing a novel type of clustering andtransmission head selection in the wireless sensor networks with increasedlifetime of network and decreased energy consumption of sensor node. Theproposed architecture consists three subsystem models for improvisingndoptimizing the network lifetime. The Clustering and Transmission HeadSelection subsystem were designed to minimize the work load of the clusterhead, which performs data gathering and data transmission. The new model isproposed to be dynamically adaptive and accurate. The Second NodeScheduling subsystem and the sensor nodes are scheduled to elect the mastertransmission head, and the packets are scheduled with QoS guaranteed.Finally, in the data encryption subsystem the secured data transmission isprovided with nodes. newline
