Dynamic frequency allocation in ad hoc networks

This paper presents a new frequency allocation scheme for ad hoc networks. Unlike other proposals, the scheme allocates frequencies to groups of nodes, for their intra-group communication needs, in order to guarantee a high level of availability of the needed frequency resources. This scheme uses a distributed decision process with interference measurements and a simple collaboration protocol between groups. Performance figures concerning the optimality of the obtained solution and the convergence time are given. The paper also presents a work that has been done to simulate this allocation scheme in a realistic environment with a mobility scenario on a 3D terrain model. Finally some ideas for future work are proposed.
