Power Analysis of a Network Using DECAP Algorithm by Varying Network Sizes and Users

Green Networking is of recent interest. Network devices like access points, switches, computer, server etc. are the major source of energy consumption. To eliminate the problem of energy wastage of Access Points switched on all the time an algorithm is introduced. In this paper, an algorithm is developed to save energy and to avoid wastage of energy due to continuously ON Access Point switches. This algorithm is applied to the centralized controller, which maintains the whole network information and configuration of Access Point, Switches, and Clients etc. A log file is also maintained to keeps track of the Sleep mode timing of the Access Points. Controller is a device that stores the information by linking the client, cluster head, secondary Access Points simultaneously. Communication between all modules (client, cluster head, secondary AP) is done by sending the packets from source to destination. In order to validate the algorithm, experiment has been carried out in Banasthali Vidyapith by varying network size, users, number of Access Points deployed etc. The presented approach works in two phase’s first is the association phase and second one is the disassociation phase. From the results, it is inferred that the proposed algorithm saves large amount of energy.
