Regarding to mobile ad hoc network characteristics which all mobile nodes of network connect to each other via wireless, one of the important aspects of this type of network is the limitation of amount of available energy in the network nodes that is the most critical factor in the operation of these networks. And the tremendous amount of using the mobile nodes in wireless communication medium makes Energy Efficiency (EE) a fundamental requirement for mobile ad hoc networks. On the other hand Cluster Based Routing Protocol (CBRP) is a robust/scalable routing protocol for Mobile Ad hoc Networks (MANETs) superior to the existing methods [1-3](For example it’s overhead of is less than while it’s throughput of is more than of AODV which is a standard protocol for MANET [4]. We added the resource management protocol to the CBRP for service advertisement and service discovery [5]. Although this protocol does not have significant overhead on the network it needs more consideration about increasing the life time and especially decreasing the energy consumption. We propose the idea of putting the idle member nodes to sleep state. The experimental results show that proposed method causes decreasing energy consumption in CBRP which results to stability of the network.
