Enhanced Channel Assignment Algorithm for Relaying Nodes in W-CDMA Multihop Cellular Network

Kishana R. Kashwan and S. G. Balakrishnan
Abstract—For newer and emerging communication technologies, it can be quite faster to deploy Multihop cellular networks (MCNs) with increased channel capacity and wider coverage area at comparatively less cost. MCNs greatly reduce the dead-spot and hot-spot problems faced by cellular networks. The channel assignment is a challenge in these networks. Several recent proposals had addressed many channel assignment problems in terms of channel conflicts, node mobility etc. However selecting nodes for relaying during the channel assignment need to be addressed for an effective channel assignment and increased throughput in MCNs. In this paper, a new algorithm, called Enhanced Channel Assignment Algorithm (ECAA) is proposed. The new algorithm enables selection of relaying nodes during channel assignment for a Time Division Duplex (TDD) Wideband Code Division Multiple Access (W-CDMA) MCN. The simulated results show that the proposed scheme ECAA is an improved option channel assignment and resulted in higher throughput.

Index Terms—Channel assignment, multihop cellular network, relaying node, throughput.
