“…• Cellular UEs transmitters: The scheduling policy at the eNB is Equal Time [8], which is interference-unaware. 2 In order to have a full understanding of the effect of the D2D transmissions on the cellular ones, we assume that cellular users are in saturation, i.e., they always have a packet ready to send.…”

This paper presents a first fully analytical approach to performance evaluation of D2D communication systems, which does not assume the system to be in saturated conditions. We adopt a Coupled Processors model to describe a cellular scenario with D2D users sharing radio resources with cellular users, i.e., adopting in-band underlay D2D schemes. We derive sufficient conditions for stability of such system, characterizing the effect of D2D transmissions on cellular user performance. Moreover, we present a computationally feasible method for the determination of a proportionally fair allocation of resources. We show that, in non-saturated networks, such an allocation sensibly improves the one derived under the assumption of saturation. Our results show the importance of accurately modelling the interdependence in users performance in the design and evaluation of a D2D cellular system. 978-1-4799-8439-8/15/$31.00 ©2015 IEEE

Scheduling is very important in real time environment, where users must be provided services by considering factors like QoS and channel quality. A novel analysis on the performance of downlink packet scheduling algorithms in Long Term Evolution (LTE) networks is presented. LTE with multimedia traffic is modelled with Network Simulator (NS-3) in compliance to 3GPP specifications. This paper analyses the performance and efficiency of different scheduling algorithms in various scenarios that includes single cell as well as multi cell environment users utilizing multimedia traffic like VoIP, Video, Gaming and Downloads.

“…By simulation using Matlab, we compare the performance of the proposed AAG-R with the previously mentioned RME [6] and RR [10]. The simulation parameters are as follows: (a) there are totally 100 RBs; (b) the average data rate granted by CAC is 1 Mbps for each UE; (c) the data generated by each UE is constant bit rate at 1 Mbps; and (d) the EWMA coefficient Į=0.35.…”

In LTE system, it is difficult for an eNB to properly allocate uplink resource blocks (RBs) to UEs as many factors complicate the issue. So far, most research has focused on maximizing system throughput. However, this is often achieved by downgrading other performance metrics and may result in the waste of resources. In this paper, a resource allocation scheme for LTE uplink is proposed which takes into account the data rate granted by call admission control (CAC). Data rate is defined based on exponentially weighted moving average (EWMA). The scheme leads to a close match between user demand and resources actually allocated, thereby making better use of the resources. In addition, robust modulation-coding is considered in resource allocation. Results obtained via simulation show that the proposed scheme demonstrates good performance in important aspects compared to other resource allocation methods.
