Resource Allocation Schemes in Evaluating the Infrastructure Cost of a Wireless Multihop Architecture with Fixed Relays
2005 (English)Conference paper (Refereed)
The downlink of a hybrid system with regenerative relaying (cellular extended by means of fixed wireless router) is studied in terms infrastructure costs. Using a static linear cost model, the feasibility of the hybrid system is analyzed by comparing the infrastructure cost of providing a predefined service level with a traditional single hop system and with a hybrid system, respectively. The analysis is performed with two resource allocation schemes: fixed and adaptive link rates. The same centralized STDMA scheme is used in both cases. The usage of adaptive rates reduces significantly the infrastructure cost of both the reference and the hybrid system. However, the hybrid system becomes feasible when the cost of a relay is 6 to 9% the cost of a base station, no matter which of the two resource allocation scheme is used.
