The more increase in network lifetime and the duration of the network performance,the better. In this paper, a protocol is proposed that postponesthe observation of thefirst sensorlosing its energy using energy balance and with the help of the multiple sink sensor network.Inthe new protocol, the network lifetime increases, andcompared to one of the best energy balanceprotocols in network named LELE, it has the abilityto reduce the network unstable periodواژگان کلیدیleader election, energy balance, multiple sink, wireless sensor network
