Periodic handover skipping in cellular networks: Spatially stochastic modeling and analysis
Kiichi Tokuyama, Tatsuaki Kimura, Naoto Miyoshi
Handover (HO) management is one of the most crucial tasks in dense cellular networks with mobile users. A problem in the HO management is to deal with increasing HOs due to network…
Time-based Handover Skipping in Cellular Networks: Spatially Stochastic Modeling and Analysis
Kiichi Tokuyama, Tatsuaki Kimura, Naoto Miyoshi
Handover (HO) management has attracted attention of research in the context of wireless cellular communication networks. One crucial problem of HO management is to deal with increa…
DeepSIP: A System for Predicting Service Impact of Network Failure by Temporal Multimodal CNN
Yoichi Matsuo, Tatsuaki Kimura, Ken Nishimatsu
When a failure occurs in a network, network operators need to recognize service impact, since service impact is essential information for handling failures. In this paper, we propo…
Distributed Collaborative 3D-Deployment of UAV Base Stations for On-Demand Coverage
Tatsuaki Kimura, Masaki Ogura
Deployment of unmanned aerial vehicles (UAVs) performing as flying aerial base stations (BSs) has a great potential of adaptively serving ground users during temporary events, such…
Spatio-Temporal Correlation of Interference in MANET Under Spatially Correlated Shadowing Environment
Tatsuaki Kimura, Hiroshi Saito
Correlation of interference affects spatio-temporal aspects of various wireless mobile systems, such as retransmission, multiple antennas and cooperative relaying. In this paper, w…
A subgeometric convergence formula for finite-level M/G/1-type Markov chains: via a block-decomposition-friendly solution for the Poisson equation of deviation matrix
Hiroyuki Masuyama, Yosuke Katsumata, Tatsuaki Kimura
This paper studies the subgeometric convergence of the stationary distribution in taking the infinite-level limit of a finite-level M/G/1-type Markov chain, that is, in letting the…
Theoretical Framework for Estimating Target-Object Shape by Using Location-Unknown Mobile Distance Sensors
Hiroshi Saito, Tatsuaki Kimura
This paper proposes a theoretical framework for estimating a target-object shape, the location of which is not given, by using mobile distance sensors the locations of which are al…
Theoretical Performance Analysis of Vehicular Broadcast Communications at Intersection and their Optimization
Tatsuaki Kimura, Hiroshi Saito
In this paper, we propose an optimization method for the broadcast rate in vehicle-to-vehicle (V2V) broadcast communications at an intersection on the basis of theoretical analysis…
Light-tailed asymptotics of stationary tail probability vectors of Markov chains of M/G/1 type
Tatsuaki Kimura, Kentaro Daikoku, Hiroyuki Masuyama +1
This paper studies the light-tailed asymptotics of the stationary tail probability vectors of a Markov chain of M/G/1 type. Almost all related studies have focused on the typical c…
