  In the paper we analyze the maximum lifetime problem in sensor networks with
limited channel capacity for multipoint-to-multipoint and broadcast data
transmission services. We show, that in order to achieve an optimal data
transmission regarding the maximum lifetime problem we cannot allow for any
interference of signals. We propose a new Signal to Interference plus Noise
Ratio function and used is to modify the Shannon-Hartley channel capacity
formula. For the modified channel capacity formula we solve the maximum
lifetime problem in one dimensional regular sensor network $L_N$ for discussed
data transmission services.
