Adaptive topology control for heterogeneous mobile ad hoc networks using power estimation
Xiaofeng Han, Chien-Chung Shen, Zhuochuan Huang · 2006
Most existing topology control algorithms for heterogeneous mobile ad hoc networks (H-MANETs) only consider non-uniform transmission power (range) and use the Euclidean distance as their metrics for topology creation. However, in practice, communication capability could be diverse not only in the maximum transmission power (range), but also in the threshold receiving power. We present a localized topology control algorithms for H-MANETs termed Topology Control with Power Estimation (TCPE). By using the technique of power estimation, TCPE directly collects the minimum transmission power among nodes for topology control without requiring any location, angle-of-arrival, or global topology information. TCPE preserves the network connectivity and greatly improves the spatial reuse and power efficiency. TCPE also includes a topology maintenance mechanism to address mobility. Simulation results demonstrate the merits of TCPE.
