Topology control adopting optimal topology over update interval in mobile ad hoc networks

A topology control method for mobile ad hoc networks is proposed, in which the optimal topology of each topology update interval is adopted by considering both the dynamic positions of one-hop neighboring nodes and cumulative energy consumption to send data over the update interval. This approach of adopting the topology optimized over the update interval differs from an existing approach in which the topology update frequency is increased. Through performance simulation, conditions under which the proposed method is applicable are revealed by comparing the energy consumption of the proposed method to that of the existing method. Additionally, the proposed method is practical because it takes only several tens of milliseconds to determine the optimal topology even when using a CPU widely used for embedded devices.
