Iterated Local Search for Minimum Power Symmetric Connectivity in Wireless Networks

摘要

The problem of finding a symmetric connectivity topology with minimum power consumption in a wireless ad-hoc network is NP-hard. This work presents a new iterated local search to solve this problem by combining filtering techniques with local search. The algorithm is benchmarked using instances with up to 1000 nodes, and results are compared to optimal or best known results as well as other heuristics. For these instances, the proposed algorithm is able to find optimal and near-optimal solutions and outperforms previous heuristics.
