Abstract: Broadband power line communications (B-PLC) is a recent developed technology of the realisation of the broadband access networks. The planning process of those networks is composed of two problems: the generalised base station placement problem and the PLC channel allocation problem (P-CAP). In this paper, the P-CAP is investigated. These investigations include the problem description, the mathematical formulation of its optimisation objectives, and the solution of the problem by the means of meta-heuristics. The channel allocation problems in B-PLC and in wireless networks are compared. The P-CAP is formulated as a multi-objective optimisation problem (MOP), where the resource reuse maximisation and interferences minimisation are the conflicting objectives. Two approaches are applied to solve the P-CAP as MOP: a classical approach that converts the multi-objective optimisation (MOO) problem into a single-objective optimisation (SOO) problem; and a more recent approach based on the MOO algorithms. The performances of SOO and MOO are evaluated by numerical experiments, using optimisation search that is based on the evolutionary algorithm.
