Abstract
The RA (Range Assignment) strategy is an art of setting nodes’ transmitting ranges to generate a network with desired properties and at the same time reducing node energy consumption and/or increasing network capacity. In this paper, a distributed RA strategy RRAS (Robust Range Assignment Strategy) is proposed. It shows mainly three advantages to most previously proposed topology control algorithms. First, it is strictly local and does not require node position information. Second, the resulting topologies of RRAS algorithm under different coefficients are available for various application scenarios, such as energy-efficient applications, real-time performance applications and so on. Third, each node can adjust the coefficient dynamically to maintain the network connected for a longer time. Analysis and simulation results are still given to demonstrate the correctness and effectiveness of our proposed algorithm.
