提出了一种新的在移动IPv6中提供服务质量保证的方案L2AMQ。L2AMQ结合分层移动管理与链路层辅助切换机理,通过检测链路层信号强度在移动节点即将进入的子网中建立提前预留,以加快QoS路径的切换速度。当移动节点在各子网间切换时,L2AMQ通过建立提前预留和最小化数据包传输路径的变化来减少QoS路径的切换延迟。L2AMQ还通过引入一个新的QoS对象,避免在分层移动管理中使用RSVP隧道,从而减小系统的额外开销,节约系统资源。仿真和分析表明,与现有协议相比,L2AMQ具有较低的预留阻塞率和切换掉线率,能较好地满足无线移动环境中实时业务的QoS需求。

＜正＞A smart home is likely in the near *** important ingredient in an intelligent environment such as a home is automatic services,which means home system itself could know or predict what the inhabitant want to do,and so provide inhabitant the services *** researches reveal that most of the services in smart home are location-dependent so the automatic services must be built on the location *** this paper we model inhabitant location pattern as a time based markov model（TMM）.The simulation result shows that compared to the other models, the TMM has a set of benefits such as less time complexity,higher prediction accuracy and faster convergences rate. These benefits make TMM meets the requirements of automatic services in smart home.

However, the major search engine hasn’t more view on the temporal information of web pages,and ignored the relationship between the keywords and time *** this paper, we focus on the need in time phrases recognition and extracting from the web pages,and identify the closely relationship between the keywords and the temporal information. The experiment results showed that the information retrieval based on temporal information is better than the information retrieval of simple text-keyword search in the capabilities of query expression and query processing.

For a hierarchical cognitive radio network(CRN),the secondary users(SUs) may access the licensed spectrum opportunistically,whenever it is not occupied by the primary users(PUs).An important issue for this kind of CRN is the achievable qualityof-service(QoS) performance,such as traffic transmission delay,which is critical to the SUs' traffic *** this paper,we focus on the delay performance analysis of the SU system and the design of the corresponding optimal access strategy for the case of SUs sharing multiple licensed *** our analysis,the transmission of PU and SU traffic is modeled as M/G/1.*** merging the PU and SU traffic,we propose the model of a priority virtual queue on the licensed *** on this model,we obtain the expected system delay expression for SU traffic through M/G/1.preemptive repeat priority queuing *** the case of multiple licensed channel access,the access strategy is further investigated with respect to the expected system delay for SU *** minimizing the expected transmission delay,the optimal access strategy is modeled as a nonlinear programming problem,which can be resolved by means of the classic Genetic Algorithm(GA).Numerical results validate our analysis and design of an optimal access ***,by considering the {1. taken by the GA approach,we can also adopt the inverse proportional access strategy to obtain near-optimal results in practice.
