Sensors are battery operated devices and are normally placed in the region where humans could not reach easily. Therefore these devices need to be used carefully so as to extend the network life. Network layer plays important role for transmission of data from source node to destination node. Considerable amount of energy is consumed for routing the data between the source and destination node. Hence, to prolong the lifetime of sensor network, it is essential to think for routing protocol that takes care of energy consumption during data transmission process. In this paper a new protocol called Advanced LEACH (ALEACH) is suggested, which is a modified version of LEACH protocol.
