Optimal Resource Allocation in Distributed Broadband Wireless Communication Systems
This paper is concerned with optimization of distributed broadband wireless
communication (BWC) systems. BWC systems contain a distributed antenna system
(DAS) connected to a base station with optical fiber. Distributed BWC systems
have been proposed as a solution to the power constraint problem in traditional
cellular networks. So far, the research on BWC systems have advanced on two
separate tracks, the design of the system to meet the quality of service
requirements (QoS) and optimization of the location of the DAS. In this paper,
we consider a combined optimization of BWC systems. We consider uplink
communications in distributed BWC systems with multiple levels of priority
traffic with arrivals and departures forming renewal processes. We develop an
analysis that determines packet delay violation probability for each priority
level as a function of the outage probability of the DAS through the
application of results from renewal theory. Then, we determine the optimal
locations of the antennas that minimize the antenna outage probability. We also
study the tradeoff between the packet delay violation probability and packet
loss probability. This work will be helpful in the designing of the distributed
BWC systems
