Dynamic channels reallocation management scheme in hierarchical cellular network

Abstract

In this paper an algorithm, called Multilayer Dynamic Channel Management scheme (ML-DCM) is proposed to reallocate channels in a hierarchical cellular network. This proposed algorithm is based on reducing the dropping handofs and on balancing load between microcells and overlaying macrocell. A continuous coverage is achieved with microcells that accommodate both new and handoff requests. Macrocell (Umbrella cells) only accept handoff requests. The strategy of this contribution tends to favor (prioritize) handoff calls to macrocell for high-speed users. This system is analysed using simulation.

An Novel User-Classified Method for Modeling and Analysis of Hierarchical Cellular Networks

“…the user's velocity is small enough so that the number of handoffs is small and may be ignored). In [4] and [5], the arrival of new and hand off calls to a cell obeys a Poisson process, and a Poisson overflow model is considered. However, only microcell-to-macrocell overflow is allowed and fast calls and slow calls are not treated equally.…”
