查询词典 Ad

After studying the MAC protocol of Ad hoc network and by modifying the Wireless Token Ring Protocol, a new uncontested Distributed Parallel Wireless Polling Access Protocol that can provide MAC QoS guarantees for Ad hoc network is presented, and the mathematical model is established by the embedded Markov chain theory and the probability generating function method. Based on it, the mean value of queue length and message waiting time are explicitly obtained.

摘要该文对Ad hoc网络的MAC层协议进行了研究，通过对无线令牌环协议进行改进，提出了一种新的具有QoS保障的无竞争的分布式并行无线轮询访问协议，并采用嵌入Markov链和概率母函数的分析方法，用限定服务规则进行了系统建模，在系统模型的基础上得到了系统的平均排队队长以及平均等待时间的解析结果。

Parties wishing to provide for arbitration but also to avoid a supervising institution sometimes draft so called ad hoc clauses, intended to be self-executing in the sense that they oblige the parties to initiate and proceed with arbitration without the assistance of a permanent institution.

上述引文谈及 ad hoc arbitration也可以选择一个管理机构，行使机构的某些职能，除了引文提及的机构外，香港国际仲裁中心也常常被选择行使对 ad hoc arbitration的一些管理职能。当事人不选择机构，便由仲裁员行使本来托付给管理机构的职能

BMSCs expressing Ad-GFP had three types of subpopulation structures under a fluorescence microscope; when the virus titer was ≥ 1×10^6 PFU/mL, BMSCs proliferation was suppressed at the early stage, in a dose-dependent manner.

荧光显微镜下可见表达Ad—GFP的BMSCs有三种亚群结构：滴度≥1 10^6PFU／mL时，BMSCs增殖在早期受到抑制，且呈剂量依赖；转染Ad—GFP的BMSCs经β一巯基乙醇诱导可分化为神经元样细胞，神经元特异性烯醇化酶阳性。

In mobile Ad Hoc networks, geographical routing protocol was a kind of important routing protocols, which requires the underlying topology be planar, sparse, connected and t-spanner in order to guarantee the delivery of message and bound the routing length. A new topology control algorithm named ODT, which constructed the geometry structure named ODT graph, was proposed.

基于移动Ad Hoc网络的特性，提出了一种适用于移动Ad Hoc网络的路由协议PAGPSR(Power-Aware Greedy Perimeter Stateless Routing)，该协议在原有的基于地理位置的路由协议GPSR的基础上增加了节点能量感知和负载均衡算法，修改了GPSR的转发策略，使网络中能量消耗和网络负荷分布更加均匀，从而延长了整个网络的生存时间。

CEQRP can provide QoS guarantee and is aimed at extending the battery"s lifetime at each node by selecting the nodes with a longb attery"s remaining lifetime to forward packets. Simulation results show that CEQRP has good network performance. Furthermore, CEQRP shows distinct performance advantages in using a nodes electric energy efficiently. 4. The issue about optimal UDP packet size for mobile Ad Hoc networks when transmitting CBR traffic is studied.

基于无线Ad Hoc网络的特性，提出了适用于无线Ad Hoc网络的路由协议CEQRP(Cost-Efficient QoS Routing Protocol)，该协议不仅能为应用层提供QoS保证，而且能充分利用网络中剩余能量高的节点来中转分组，从而达到有效利用节点的电能、提高网络&寿命&的目的。
