An Energy Efficiency Enhanced through Duty Cycle based on Clusters in Wireless Body Area Network

Wireless body area network (WBANs) plays an important role in monitoring and helping the patient to maintain the health surveillance system. In this research paper, a variable duty cycle-based clustering algorithm is designed to increase the energy efficiency, by varying the awake and sleep period according to the criticality of the sense data that need to be transmitted. In the proposed approach, the network consists of two phases as LEACH Protocol. first steady phase and second setup phase. Firstly, applying the variable duty cycle and distance centroid has a maximum energy of alive node is considered as initial cluster heads (CHs). The successive CHs are recognized based on residual energy based on the threshold distance from the current cluster head (CH). After the formation of the clusters, the Cluster head aggregates the emergency data through alive nodes in Variable duty cycle values and sends it to the base station. In this algorithm no need to transmit the data in normal conditions of the patient (i.e.) they are dead nodes This technique provides more energy efficiency in the network. The performance evaluation of the proposed protocol Energy Efficient Duty Cycle-Based Cluster Approach (EEDCCA) is done using MATLAB tool and results are analyzed. The simulation result validates that the proposed technique increases the energy efficiency of the network and also Enhancement of Lifetime of the whole WBAN network.
