Performance Analysis and Optimization of an Improved Dynamic Movement-Based Location Update Scheme in Mobile Cellular Networks

چکیده
In this study, we propose an improved version of the dynamic movement-based location update scheme that stores all cells visited by the MS, and their neighboring cells, to reduce the location update cost of the dynamic movement-based location update scheme. We show that a significant reduction in the location update cost is achieved in our scheme. We also show that our scheme has optimal total cost when the threshold is rather small. Additionally, the MS requires a minimal amount of memory to successfully implement our scheme.

An Enhanced Location - Based Location Update Scheme in Mobile Cellular Networks
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 movement-based location update scheme [4] is one of the easily implementable approaches. According to this scheme, each MS...

-We study a dynamic mobility management scheme: the movement-based location update scheme. An analytical model is applied to formulate the costs of location update and paging in the movement-based location update scheme. The problem of minimizing the total cost is formulated as an optimization problem that finds the optimal threshold in the movement-based location update scheme. We prove that t...

متن کاملMovement-Based Location Update and Selective Paging for PCS Networks - Networking, IEEE/ACM Transactions on
This paper introduces a mobility tracking mechanism that combines a movement-based location update policy with a selective paging scheme. Movement-based location update is selected for its simplicity. It does not require ea& mobile terminal to store information about the arrangement and the distance relationship of all cells. In fact, each mobile terminal only keeps a counter of the number of c...
