A finite random graph generated by continuous time birth and death processes with exponentially distributed waiting times was investigated,which is similar to a communication network in daily life.The vertices are the living particles,and directed edges go from mothers to daughters.The size of the communication network was studied.Furthermore,the probability of successfully connecting senders with receivers and the transmitting speed of information were obtained.
