Abstract :
In this paper we propose a new problem named energy-efficient multi-lingual cell broadcasting(EEML-CB) to support multi-lingual service in cell broadcasting system. We prove that the problem is NP-hard and then propose ILP model as well as a greedy algorithm named smart multi-lingual cell broadcasting (SMCB). We evaluated our heuristic by simulations.
