The main idea is to design an algorithm for reducing the amount of overhearing problem in MANET using DSR. Applied approach: a cross layer framework is designed such that the physical, MAC and network layer. RSS value is applied with the physical layer for finding the mobility. Mobility determines the rebroadcast capability and overhearing level. The energy conservation is achieved due to cross layer framework and by integrating 802.11 with Dynamic Source Routing (DSR). In Power Save Mode (PSM) initially all the nodes are in sleep state, but disadvantage occurs in case of unconditional overhearing. The conditional overhearing is proposed such that the energy consumption is reduced.
