A Minimum Cost Handover Algorithm for Mobile Satellite Networks
移动卫星网络中基于最小费用的切换算法

In mobile satellite networks, for the aim of shortening handover delay while using network resource efficiently, a proper handover scheme should be given. In this paper, by introducing the interrupting probability and the cost model of service, triggering schemes for path optimization in handover is given. Here, a novel mobile Satellite networks Minimum Cost Handover (SMCH) algorithm is proposed. This algorithm can assure the Quality of Service (QoS) parameters (such as delay) during the handover, as well as can minimize the handover cost. So it can use the network resource efficiently after the handover. Correlative simulation indicates that this novel algorithm is superior to other current algorithm in respect of guaranteeing the QoS and decreasing handover cost. Besides, it also has more adaptability and more practicability.
