Mobility-Aware Distributed Topology Control for Mobile Multi-hop Wireless Networks
In recent years mobile multi-hop wireless networks have received significant attention and one of the major research concerns in this area is topology control. While topology control problem in ad hoc networks is NP-complete, several heuristic and approximation based solutions have been presented. However, few efforts have focused on the issue of topology control with mobility. In this paper, we introduce a new topology control scheme in the presence of mobile nodes. The proposed scheme predicts future proximity of neighboring nodes and applies power control such that the network connectivity is maintained while reducing energy consumption. Simulation results show that the optimal power selection based on location prediction gives better performance in terms of energy and connectivity.
