In mobile ad-hoc network, the nodes are mobile and can communicate dynamically in an arbitrary manner. These flexibility in designing the network formation helps to design a network anywhere and anytime. This makes MANET's suitable for many different applications ranging from military to commercial. And also, these are very much suitable for disaster management, rescue operations and defense applications. The major concern in MANET is the conservation of energy due to the limited lifetime of mobile devices. All the mobile nodes depend on the battery power supply. The main objective of the paper here is to make the 802.11 PSM suitable for MANET multihop with Dynamic Source Routing (DSR) protocol. The overhearing problem is due to the integration of DSR protocol with 802.11 PSM.
