We propose a new multicast scheduling scheme which can achieve the proportional fair (PF) allocation in the wireless cellular systems. In case of multicast, the scheduler in the base station should select a group of users, instead of one user, among all users who request the multicast contents. Therefore, multicasting scheduling problem is equivalent to deciding a certain modulation and ...

Mobility is one of the major issues in the performance characterization of wireless communication systems. Wireless communication systems encounter failures. These failures can occur because of software, hardware, human error, or a combination of these factors. The probability of an ongoing call being dropped due to a handoff failure and the probability of a new call being blocked due to the temporary unavailability of an idle channel are main metrics that affect the performance of wireless cellular systems. In order to overcome this problem, availability and performance of these systems should be considered together. In this paper, cellular networks with failures and recovery are modelled. The model is based on previous work in performance modelling and availability modelling of such systems. A Markov reward model is used to represent such a system with handoffs. Mean queue length and blocking probability are calculated using an analytical model and presented.
Knowledge and prediction of system occupancy in wireless cellular systems such as UNITS can play an important role in the optimization of resources allocation procedure. In fact, a resource allocation scheme can make use of such knowledge to anticipate system overloads. On the other hand, studies show that a user's movements in a cellular network can be predictable. Thus, handover prediction methods can be used to improve resource allocation scheme. Two fundamentally different approaches can be found in handover prediction: cell approaches that make use of global knowledge of user traffic flows in a particular cell; and user approaches that rely on the knowledge of user mobility in short or long term. Short-term methods that predict user speed and location are not studied here. Long-term methods are based on the learning of users' behaviors by computing profiles for each user. In this paper, we describe two handover predictions methods: cell and user profile based. We also propose a simulation model that enables a comparison of the two approaches.
Although the conventional way, which means shrinking the cover of each cell and increasing the density of base stations for sharing radio resources among more cells, can be adopted to relieve the urgent requirements for more capacity and adapt to the vulnerable propagation character of higher spectrum, frequent handoffs from cell to cell are becoming a great burden for wireless cellular system. This paper addresses an adaptive handoff-relieving scheduling algorithm for downlink transmission in a time-slotted shared wireless network that considering both the on-line channel condition and velocity information together. And simulation results indicate that this scheduling scheme can absolutely relieve the handoff overhead and create a good experience for the subscribers.
Third generation wireless networks are expected to carry traffic from heterogeneous sources of voice, data, video or multimedia with a specified quality of service. We investigate how packet transfer mode over the radio interface can increase the efficiency of radio resources when there is multiple coverage of overlapping cells. Our discussion is focused primarily on multiple link packet protocol operation and its performance. We present an analysis of the system performance using a Markov modulated Poisson process (MMPP) for the aggregate of ON-OFF state traffic and for the overflow processes and quantify the performance improvement through a numerical example.
We propose a new multicast scheduling scheme which can achieve the proportional fair (PF) allocation in the wireless cellular systems. In case of multicast, the scheduler in the base station should select a group of users, instead of one user, among all users who request the multicast contents. Therefore, multicasting scheduling problem is equivalent to deciding a certain modulation and coding level and a group of users who have better enough channel quality to decode the multicast data. In this work, we first extend the PF metric to the extent that the scheduler can reflect the user's time varying channel gain and fairness not only in the unicast case but also in the multicast transmission. Based on the extended PF metric, we propose a PF multicast scheduler and evaluate its performance. Our proposed algorithm outperforms other multicast scheduling schemes in terms of aggregated throughput as well as the fairness among all users.
Ad hoc relaying schemes are introduced as an effective mechanism for load balancing in wireless cellular systems. The relays facilitate channel sharing between the adjacent sectors of the neighboring cells, for the calls that are originated within their coverage area. In this paper, two configurations for relay deployment in sectorized cellular systems are presented. In each case, the probability of blocking in presence of limited-coverage relays and constrained channel sharing is derived. Numerical results verify that the proposed hybrid schemes achieve significantly better grade of service compared to conventional cellular networks.
In this paper, we study the benefits of using iterative multi-user detectors for co-channel interference suppression in wireless cellular systems. We show that with a single receive antenna a receiver is capable of detecting and cancelling a single in-band interferer using the same modulation and coding scheme as the desired signal. We investigate the benefits of using such an interference canceller at the mobile unit in the downlink scenario of wireless cellular networks. Significant improvements in terms of the average system throughput and outage probability are achieved with iterative interference cancellation. The effectiveness of the interference canceller allows us to consider more aggressive frequency reuse schemes, such as using smaller cluster sizes, and using three-sectored cells where all sectors share the same frequency band.
One of the key performance measures in wireless cellular systems is the handoff dropping probability. The paper studies the handoff performance for an integrated voice/data wireless cellular system. Specifically, we propose a new handoff control policy, called dual trunk reservation with queuing (DTR-Q). It uses two thresholds, one to reserve bandwidth for voice handoff, and the other for managing the data traffic. By taking advantage of the adaptiveness of data traffic, it uses a single queue to buffer the data request further in case the requested bandwidth is not available. The unique features of the proposed DTR-Q scheme are: 1) it can provide the necessary service guarantee and service differentiation for voice and data traffic; 2) it adopts a complete sharing approach that can maximize the channel utilization. We propose an analytical model to calculate the key performance measures, and thoroughly investigate system performances under a variety of system parameters.
There are many benefits in using time division duplex (TDD) instead of frequency division duplex (FDD) schemes in fixed wireless cellular systems. To name a few; channel reciprocity for the single carrier frequency used on both up and downlinks will allow easy access to channel state information, reduced complexity of RF design, much higher flexibility in handling dynamic traffic, simpler frequency plan, etc. However, there exists a serious limiting factor in using dynamic-TDD (D-TDD) in cellular systems. This is due to a steady interference on uplinks in a cell, caused by downlink transmissions of other cells. Simulation results show in D-TDD cellular systems, performance is unacceptable, when omni-directional antennas are used at base stations. Simulation results have also demonstrated a great potential for smart antennas in fixed D-TDD bandwidth-on-demand wireless systems.
We examine techniques for increasing spectral efficiency of cellular systems by using slow frequency hopping with dynamic frequency-hop pattern adaptation. The adaptation is driven by rapid frequency quality estimates. We present simulation studies that express system performance by calculating code word error cumulative distribution functions. The impact of path loss, shadowing, Rayleigh fading, co-channel interference, voice activity and occupancy is monitored. Simulations have been done for circuit-switched systems. The paper investigates: (a) full-replacement dynamic frequency hopping (DFH); (b) worst- dwell DFH; and (c) threshold-based DFH. The results show that full-replacement dynamic frequency hopping can support twice as many users as random frequency hopping. The two other techniques perform worse than the full-replacement technique, but better than random hopping.
