    Future increase of mobile communication subscribers will require a great capacity expansion of the cellular systems. In order to accommodate the increasing number of subscribers, the cell size will have to be much smaller than current size. Therefore, it is predictable that the l

  • A Prediction-Based Location Update Algorithm in Wireless Mobile Ad-Hoc Networks

    سند علمی۲۰۰۵ICCNMCJun Shen, Kun Yang, Shaochun Zhong

    Location information in Mobile Ad Hoc Networks (MANETs) provides efficiency to uni-cast and multi-cast algorithms. This paper proposes a new location update algorithm called PLU. The essence of PLU lies in the integration of location prediction and one-hop broadcasting of locatio

  • RoadTrack: Scaling Location Updates for Mobile Clients on Road Networks with Query Awareness

    سند علمی۲۰۱۰PVLDBPéter Pesti, Ling Liu, Bhuvan Bamba, Arun Iyengar

    Mobile commerce and location based services (LBS) are some of the fastest growing IT industries in the last five years. Location update of mobile clients is a fundamental capability in mobile commerce and all types of LBS. Higher update frequency leads to higher accuracy, but inc

  • An Enhanced Location - Based Location Update Scheme in Mobile Cellular Networks

    سند علمی۲۰۰۵Jang Hyun Baek

    Effective location tracking strategy is essential to improve the utility of radio channels [1]-[6]. Due to the limited battery life and computational capacity in a mobile station (MS), one desirable feature of a location update scheme is its easy implementation in the MS. A movem

  • Performance evaluation of location update schemes for MANET

    سند علمی۲۰۰۹Int. Arab J. Inf. Technol.Khaled Ahmed Abood Omer, D. K. Lobiyal

    In this paper, we have developed an analytical model to evaluate the performance of home agent, quorum based, and grid location service update schemes using Markov chain. The model evaluates the performance in terms of the cost of updates and queries. The cost of updates is compu

  • A selective location update strategy for PCS users

    سند علمی۱۹۹۹Wireless NetworksSanjoy K. Sen, Amiya Bhattacharya, Sajal K. Das

    A new location update strategy for personal communication services (PCS) networks and its implementation using a genetic algorithm are proposed. Most of the practical cellular mobile systems partition a geographical region into location areas (LAs) and users are made to update on

  • Analytical Results for Optimal Choice of Location Update Interval for Mobility Database Failure Restoration in PCS Networks

    سند علمی۲۰۰۰IEEE Trans. Parallel Distrib. Syst.Yuguang Fang, Imrich Chlamtac, Hong-Bing Fei

    ÐWhen the location information for a mobile user in the Home Location Register (HLR) is corrupted or obsolete, the new arriving calls to the user may be lost. In order to minimize the effect of such HLR mobility database failure, a location update scheme called period location up

  • An Adaptive Direction-Based Location Update Scheme for Next Generation PCS Networks

    سند علمی۲۰۰۲DEXADong-Xiu Ou, Kam-yiu Lam, De-Cun Dong

    1 The work described in this paper was partially supported by a strategic grant from the City University of Hong Kong [Project No. CityU 7001259]. Abstract. This paper studies the location management problem in PCS network. An adaptive direction-based location update (ADBU) schem

  • Hash-Based Paging and Location Update Using Bloom Filters

    سند علمی۲۰۰۴MONETPars Mutaf, Claude Castelluccia

    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 terminal
