Extension of the lifetime for a sensor network is important for most if not all applications. We propose a method to extend network lifetime by introducing several special sensors with higher battery power than normal sensors. We use these special sensors as cluster heads until their battery capacity is reduced to that of a normal sensor node before adopting a low-energy adaptive clustering hierarchy (LEACH) type method. It is shown in this work that the network lifetime can be more than… CONTINUE READING
