Current P2P systems do not fit well into mobile environments where each node have to follow multi-hop path routing and have to face unpredictable mobility. If current P2P systems are deployed on the MANET, application layer and network layer both perform different routing mechanism independent of each other, resulting in multiple layer routing redundancy. Current adhoc network protocols do not fulfill the P2P requirements as basically they all are flooding based protocols. Here, we propose a new controlled-flooding based approach which works at network layer and helps P2P systems to work in mobile environment efficiently.

-To guarantee the performance of ad hoc networks, utilizing a hierarchical architecture model is necessary. An instance of this structure is clustering. In this paper a cluster-based topology control algorithm is proposed which builds an energy-efficient and a low interference topology. It uses low-quality information, exchanges a few messages, and does not need for extra hardware equipment as well. It is also suitable for practical use, because in the implementation of this algorithm is not needed to know the location or the direction information of the network nodes. So it is possible to classify this algorithm as a neighbor-based topology control algorithm. In addition, for the transmitting and the maintained power levels of each node, a modification is applied according to the real hardware platforms. It improves the energy consumption in the ideal conditions.
