ACSW Frontiers - Location Management in pervasive systems
2020Co-Authors: Jadwiga Indulska, Peter SuttonAbstract:Pervasive systems require context awareness in order to be able to provide "anywhere, anytime" computing to mobile users. One type of context information is Location information: pervasive systems require knowledge of the Location of users, devices and services. This paper reviews Location Management for pervasive systems. The review is based on our experience in the development of a Location Management system. Issues discussed include the types of Location sensors (which are categorised as physical, virtual or logical); the processing of Location information; and an architecture for a Location Management system. Three issues of ongoing importance are discussed in greater detail. These are Location conflict resolution (i.e., how can the Location of an entity be determined when multiple sensors provide conflicting information); the security and privacy of Location information; and scalability issues in Location Management.

Dynamic VLR Based Location Management Scheme for pes Networks
2020Co-Authors: S. Suresh Jothi Kumar, Chiranjeev KumarAbstract:Location Management plays a central role in guaranteeing the effective operation of Personal Communication Service (PCS). In this paper, a dynamic visitor Location register (VLR) based Location Management scheme is proposed for PCS networks. In this scheme, the current mobile switching center (MSC) gathers the information about the mobile terminals from the previous MSC of mobile terminal (MT), and performs the Location registration. This proposed scheme decreases the traffic over the home Location register (HLR) and it also reduces the Location Management cost. An analytical model is developed to evaluate the performance of the proposed scheme Keywords-Location Management, Location Management cost, Location registration, PCS networks.

Modelling and cost analysis of Location Management scheme for PCS networks
International Journal of Information and Communication Technology, 2011Co-Authors: Sanjay Kumar Biswash, Chiranjeev KumarAbstract:Location Management is a fundamental issue of mobility Management. It tracks the current Location of mobile subscriber and delivers the incoming calls to them. In this paper we have proposed a modeling to estimate the Location Management cost, which is based on home Location register cost, visitor Location register cost, signalling cost, and paging cost. The proposed analytical model is helpful in describing the various parameters for overall Location Management cost. The numerical analysis has been carried out to explain the Location Management cost.

A caching scheme for dynamic Location Management in PCS networks
2003 IEEE 58th Vehicular Technology Conference. VTC 2003-Fall (IEEE Cat. No.03CH37484), 2020Co-Authors: Jie Li, Hisao KamedaAbstract:This paper addresses caching for Location Management in personal communication service (PCS) networks. Caching is useful to reduce the delay of locating frequently retrial calls to a mobile user. However, the cached information may be obsolete due to the mobility of mobile users, which is the reason for the degradation of system performance. We introduce an efficient caching scheme for dynamic Location Management to improve the Location Management performance. Moreover, we establish an analytical model and perform a performance evaluation to study the performance improvement of the caching scheme over the non-caching scheme. We provide a simple and direct way of caching based on dynamic Location Management.

An improved movement-based Location Management scheme for PCS network
2003 IEEE 58th Vehicular Technology Conference. VTC 2003-Fall (IEEE Cat. No.03CH37484), 2003Co-Authors: Lei Li, Jie LiAbstract:Location Management is a key issue in the operation of wireless networks. A lot of Location Management schemes have been proposed. The movement-based Location Management strategy is the one that is not only efficient but also easy to implement. However, when the number of roaming users increases, the access to the home Location register (HLR) and the associated signaling cost may increase explosively under the movement-based strategy. In this paper, we introduce the concept of master HLR and current HLR. In our presented scheme, the mobile terminal (MT)'s HLR is changed dynamically and the MT will always be served by its nearest (current) HLR. A follow up simulation study shows the proposed scheme gives better performance than current movement-based schemes in term of Location Management cost.

Analysis of dynamic Location Management for PCS networks
IEEE Transactions on Vehicular Technology, 2002Co-Authors: Jie LiAbstract:Location Management is a key issue in personal communication service (PCS) networks. Performance analysis plays important roles in the implementation of Location Management methods and system design in PCS networks. Existing PCS networks have the home Location registers (HLRs) and visitor Location registers (VLRs) architecture for Location Management. Some interesting dynamic Location Management methods are proposed to improve the system performance of PCS networks. However, the existing performance analysis of the dynamic Location Management methods are too simple and not available for PCS networks with real HLR/VLR architecture. One of the reasons is the complexity and difficulty of the problem. In this paper, we challenge the problem and successfully establish a new analytical model available for the analysis of the important dynamic movement-based Location Management method for PCS networks.

Artificial immune system (AIS)-based Location Management scheme in mobile cellular networks
Iran Journal of Computer Science, 2018Co-Authors: Sanjay Kumar Biswash, Mahasweta Sarkar, Dhirendra Kumar SharmaAbstract:In this paper, we are proposing a bio-inspired Location Management (LM) technique for personal communication system (PSC). It is based on artificial immune system (AIS), with self-adaptation and self-update attributes to perform the Location Management, and helps to achieve better quality of service (QoS) and quality of experience (QoE) for the mobile users. Here, we are suggesting a modified mobile switching center (MSC) architecture, and an adaptive self-modified Location Management procedure. The proposed mobile switching center architecture has an advantage of rule-based and fact-based system to store the rules and facts related to Location Management procedure, and it shows the intelligent behavior of system. The mobile switching center calculates the best method for Location Management and the rule-based system trigged the rules to perform the techniques. The system stores the result (techniques for Location Management) in fact-based system for future use. The efficiency and effectiveness of the proposed techniques have been analyzed, and it observed that the proposed system has 45–50% improvement in performance over the current Location Management techniques. Here, we are using performance parameters such as signaling cost, database update cost, overhead measurement, and mobility Management cost.

IEEE-International Conference On Advances In Engineering Science And Management (ICAESM -2012), 2012Co-Authors: Ashish Kumar Mishra, Rama Shanker Yadav, Sanjay Kumar BiswashAbstract:Location Management is a fundamental issue of the personal communication system. In this paper we have introduced a novel technique of Location Management. The proposed scheme is based on data replication from old home Location register to current home Location register of the mobile terminal. Here the current home Location register replicate the data from old home Location register then perform the Location registration for mobile terminal. It has been observed that the proposed technique will reduced the Location Management cost and communication overheads in the network.
