Binomial probability distribution with QOS support for health monitoring in wireless body area network communication

RA Isabel, E Baburaj

Wireless Body Area network (WBAN) is a new technology used for patient health care monitoring in many application like military, entertainment etc. Quality of service (QoS) is an essential demand in WBAN as neighboring nodes at different state information has to be monitored in exact manner. But, network lifetime gets reduced due to large amount of energy consumption while transmitting the healthcare data packets from source to the sink node. In order to increase the network lifetime and reduce the energy consumption while transmitting the healthcare data packets, Binomial Probability Distribution with QoS Support (BPD-QoSS) Technique is designed in WBAN. Initially, the energy consumed by the node is calculated and higher energy nodes are grouped after calculating the energy consumption of each node. The energy consumption gets reduced by transmitting the healthcare data packets through cluster head. Then, the cluster head in the cluster is selected by using binomial probability density function. Finally, after cluster head selection, the healthcare data packets are sent to the sink node from source node with minimum energy consumption and therefore improve the network lifetime. The simulation result shows that Binomial Probability Distribution with QoS Support (BPDQoSS) Technique reduces energy consumption with higher throughput level and increases the network lifetime compared to state-of-the-works.
