É muito importante rastrear com precisão e eficácia o movimento de cada terminal móvel nas redes de comunicações pessoais. Consequentemente, são propostos na literatura vários esquemas de actualização de localização dinâmica que reflectem o padrão de movimento do terminal móvel. Esquemas importantes incluem esquemas de atualização de localização baseados em tempo, movimento, distância e direção. Neste artigo, pretendemos melhorar o desempenho do esquema de atualização de localização baseado em movimento, que é simples de implementar e apresenta bom desempenho. O esquema de atualização de localização proposto reflete as características de movimento de cada terminal móvel e reduz o número de atualizações de localização desnecessárias. O desempenho do esquema proposto é avaliado e comparado com o esquema de atualização de localização baseado em movimento proposto anteriormente através de simulação. O esquema de atualização de localização proposto requer três elementos de memória para manter o histórico de movimento no terminal móvel. Os resultados da simulação mostram que o custo de gerenciamento de localização é significativamente reduzido, especialmente para o caso com pequena relação chamada/mobilidade, minimizando as atualizações de localização desnecessárias intrínsecas ao esquema de atualização de localização baseado em movimento.

Abstract: It is very important to accurately and effectively track the movement of each mobile terminal in the personal communications networks. Accordingly, various dynamic location update schemes reflecting the mobile terminal's moving pattern are proposed in the literature. Important schemes include time-based, movement-based, distance-based, and direction-based location update schemes. In this paper, we intend to improve the performance of the movement-based location update scheme which is simple to implement and shows good performance. The proposed location update scheme reflects each mobile terminal's movement characteristics and reduces the number of unnecessary location updates. The performance of the proposed scheme is evaluated and compared with the previously proposed movement-based location update scheme through simulation. The proposed location update scheme requires three memory elements to maintain the movement history in the mobile terminal. The simulation results show that the location management cost is significantly reduced especially for the case with small call-to-mobility ratio by minimizing the unnecessary location updates intrinsic in the movement-based location update scheme.
