Este artigo propõe um esquema de alocação de largura de banda que melhora a degradação da qualidade da comunicação devido a handoffs em redes móveis multimídia. Em geral, uma chamada multimídia consiste em diversas chamadas componentes. Por exemplo, uma chamada de vídeo consiste em uma chamada de voz e uma chamada de vídeo. Em ambientes realistas, cada chamada componente incluída em uma chamada multimídia pode ter requisitos diferentes de qualidade de serviço (QoS) entre si, e as prioridades entre essas chamadas componentes muitas vezes existem com relação à importância para as comunicações. Quando a largura de banda disponível não é suficiente para uma chamada de handoff, o esquema proposto elimina uma chamada componente de baixa prioridade e adia a alocação de largura de banda para uma chamada componente cuja QoS relacionada ao atraso não seja estrita. Além disso, na alocação, o esquema dá prioridade a novas chamadas e chamadas de transferência em detrimento de uma chamada diferida e também realiza realocação de largura de banda para chamadas componentes eliminadas. Por simulação computacional, avaliamos o desempenho, como a probabilidade de queda de chamadas, e mostramos a eficácia do esquema proposto.

Abstract: This paper proposes a bandwidth allocation scheme which improves degradation of communication quality due to handoffs in mobile multimedia networks. In general, a multimedia call consists of several component calls. For example, a video phone call consists of a voice call and a video call. In realistic environments, each component call included in one multimedia call may have different requirements for quality-of-service (QoS) from each other, and priorities among these component calls often exist with respect to importance for communications. When the available bandwidth is not enough for a handoff call, the proposed scheme eliminates a low priority component call and defers bandwidth allocation for a component call whose delay related QoS is not strict. Moreover, in the allocation, the scheme gives priority to new calls and handoff calls over a deferred call and also performs bandwidth reallocation to eliminated component calls. By computer simulation, we evaluate the performance such as call dropping probability and show effectiveness of the proposed scheme.

In general, a multimedia call consists of several component calls. For example, a video phone call consists of a voice call and a video call. In realistic environments, each component call included in one multimedia call may have different requirements for quality-of-service (QoS) from each other, and priorities among these component calls often exist with respect to importance for communications. When the available bandwidth is not enough for a handoff call, the proposed scheme eliminates a low priority component call and defers bandwidth allocation for a component call whose delay related QoS is not strict. Moreover, in the allocation, the scheme gives priority to new calls and handoff calls over a deferred call and also performs bandwidth reallocation to eliminated component calls.
