Maximization of system lifetime in body sensor networks

In this paper, the target is to reduce the energy consumption in the body sensor network as well as maximize the system lifetime of sensor nodes when they will make communication among body sensors and personal communication unit. The best compression technique like LPC is selected for energy saving based on some calculations. Formulation of a linear programming problem where is to maximize the system lifetime which is equivalent to the time until the first node runs out of battery. Maximum system lifetimes are calculated by MATLAB optimization technique using and without using efficient compression algorithm like LPC in various environments. The results show that maximum system lifetimes calculated in different scenarios using efficient compression technique like LPC is better than without using compression technique.
