Proactive transmission-based QoS provisioning for multicast and broadcast services in mobile WiMAX systems

Ji Hoon Lee, Ted "Taekyoung" Kwon, Yanghee Choi, Sangheon Pack
2009 Proceedings of the 1st ACM workshop on Mobile internet through cellular networks - MICNET '09  
Mobile WiMAX systems have gained much attention for high transmission rates in cellular environments.  ...  In this paper, we propose to transmit the streaming packets of MBSs proactively and probabilistically, so that the average handover delay perceived by a user is stochastically guaranteed.  ...  But this work lacks a study of the effect of MBS zone sizes, and the inter-MBS zone handover scenario is not considered at all.  ...

A Hybrid Approach for Radio Access Technology Selection in Heterogeneous Wireless Networks

Melhem El Helou, Samer Lahoud, Marc Ibrahim, Kinda Khawam, Bernard Cousin, Dany Mezher
2015 Wireless personal communications  
Mobile users are assisted in their decisions by the network that broadcasts cost and QoS information. Our hybrid approach involves two inter-dependent decision-making processes.  ...  This paper tackles the Radio Access Technology (RAT) selection, a key CRRM functionality, and proposes a hybrid decision framework that dynamically integrates operator objectives and user preferences.  ...  An inter-RAT handover is triggered only when another RAT can provide users with significantly higher satisfaction level. This helps to reduce unnecessary handovers (i.e., ping-pong effect).  ...

2017 PLoS ONE  
The deployment of large number of femtocell base stations allows us to extend the coverage and efficiently utilize resources in a low cost manner.  ...  The proposed schemes determine handover decisions that contribute most to the network throughput and are proper for distributed implementations.  ...  Besides, a hysteresis is applied in order to avoid ping-pong effect [6, 9] . This hysteresis is a portion of the throughput and can be seen as a cost for each handover procedure.  ...
