In this paper, the authors have proposed a dynamic clustering mechanism to deal with power heterogeneous MANET. It will make clustering more efficient and flexible. The proposed system will enhance protocol to work well in dynamic clustering environment. The overhead incurred during clustering is less. The channel space utilization and network throughput can be largely improved. There are several issues in MANET which directly hampers power efficiency. MANETs with high power nodes can improve network lifetime, scalability, connectivity and robustness. However, the power heterogenousity in MANET affects the throughput severely. To improve power efficiency in MANETs, here, they have developed Dynamic Loose Virtual Clustering algorithm (DLVC). Assigning roles dynamically increases the lifetime of nodes and hence the lifetime of network.
