An Effective Cluster-Based Routing With Link Quality For Power Varied Manets

Abstract

The fast paced progress in the Mobile Ad Hoc Networks (MANETs) has enabled the use of a number of wireless applications on the move. These MANETs exhibit heterogeneity in the power levels. In such a heterogeneous network, different devices are likely to have different capacities and are thus likely to transmit data with different power levels. With high-power nodes, MANETs can improve network scalability, connectivity, and broadcasting robustness. However, the throughput of power heterogeneous MANETs can be severely impacted by high-power nodes. In this paper, we develop a loose-virtual-clustering-based (LVC) routing protocol for power heterogeneous MANETs, i.e., LRPH. To explore the advantages of high-power nodes, we develop an LVC algorithm to construct a hierarchical network and to eliminate unidirectional links. To reduce the interference raised by high-power nodes, we develop routing algorithms to avoid packet forwarding via high-power nodes. We demonstrate the system implementation and experimental results through simulations in Network Simulator [ns2].
