modeling umts power saving with bursty packet data traffic
IEEE Transactions on Mobile Computing, 2007Co-Authors: Shunren Yang, Shengying Yan, Huinien HungAbstract:The universal mobile telecommunications system (UMTS) utilizes the discontinuous reception (DRX) mechanism to reduce the power consumption of mobile stations (MSs). DRX permits an idle MS to power off the radio receiver for a predefined sleep period and then wake up to receive the next Paging Message. The sleep/wake-up scheduling of each MS is determined by two DRX parameters: the inactivity timer threshold and the DRX cycle. In the literature, analytic and simulation models have been developed to study the DRX performance mainly for Poisson traffic. In this paper, we propose a novel semi-Markov process to model the UMTS DRX with bursty packet data traffic. The analytic results are validated against simulation experiments. We investigate the effects of the two DRX parameters on output measures including the power saving factor and the mean packet waiting time. Our study provides inactivity timer and DRX cycle value selection guidelines for various packet traffic patterns.

A Hash-Based Paging and Location Update Procedure
2007Co-Authors: Pars Mutaf, Claude CastellucciaAbstract:We propose a hash-based Paging and location update procedure that reduces the Paging cost in cellular systems. By applying a Bloom lter, the terminal identi er eld of a Paging Message is coded to page a number of terminals concurrently. A small number of terminals may wake up and send what we call \false location updates" although they are not being paged. We compare the total number of Paging and false location update Messages with the cost of the normal Paging procedure. The larger the size of the terminal identi er, the less probable are false location updates. Therefore, hash-based Paging especially shows promise for cellular systems based on Mobile IPv6 with 128-bit mobile host addresses

hash based Paging and location update using bloom filters a Paging algorithm that is best suitable for ipv6
Mobile Networks and Applications, 2004Co-Authors: Pars Mutaf, Claude CastellucciaAbstract:We develop and analyze a hash-based Paging and location update technique that reduces the Paging cost in cellular systems. By applying a Bloom filter, the terminal identifier field of a Paging Message is coded to page a number of terminals concurrently. A small number of terminals may wake up and send what we call "false location updates" although they are not being paged. We compare the total number of Paging and false location update Messages with the cost of the standard Paging procedure. Fortunately, the false location update probabilities can be made very small, and important bandwidth gains can be expected. The larger the size of the terminal identifier, the less probable are false location updates. Therefore, hash-based Paging especially shows promise for IP Paging in mobile IPv6 networks with 128-bit mobile host addresses.

On Timing Reacquisition and Enhanced Primary Synchronization Signal (ePSS) Design for Energy Efficient 3GPP LTE MTC
IEEE Transactions on Mobile Computing, 2017Co-Authors: Naveen Mysore Balasubramanya, Gustav Vos, Lutz Lampe, Steve BennettAbstract:Machine Type Communications (MTC) is one of the major drivers for the future growth of the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE)/LTE-Advanced (LTE-A) standards. A primary challenge associated with MTC using LTE/LTE-A is to cater to varied requirements of the User Equipment (UE) like coverage enhancement, low complexity, low power consumption, etc. The current LTE/LTE-A standards incorporate the Discontinuous Reception (DRX) mechanism for reduced energy consumption where the UE wakes up periodically to check for a Paging Message from the base-station. On each wake-up occasion, the UE has to decode the Paging information, which requires accurate timing resynchronization. In the case of the MTC UEs, especially when the devices are deployed in low coverage areas, the resynchronization consumes a significant amount of time which increases the ON time of the UE leading to higher energy consumption. In this paper, we introduce the Enhanced Primary Synchronization Signal (ePSS) within the LTE/LTE-A standardization framework and propose a novel DRX mechanism which uses our ePSS for faster resynchronization and reduced energy consumption. We demonstrate that our mechanisms are more energy efficient than the legacy DRX mechanism for the MTC UEs with coverage enhancement.
