Mobile computing and wireless telephony are increasing converging, with manyhandheld devices (e.g., PALM Treos and RIM Blackberries) able to assume roles aseither cellular telephones or as computers. A key research question that arises as aconsequence of this convergence is whether the strategies such as virtualization used forisolation and resource sharing in larger cabled computers will be applicable to machinesthat are limited by size, computational power and battery life. This question also has greatbearing on the extent to which NSF's proposed GENI initiative will impact the mostnumerous network endpoints (there are more than 2 billion GSM mobile phones in use,for example).The project focuses on an experimental effort to anticipate this need and provide a definitiveanswer to the question of resource division and isolation in handheld devices. Ourcandidate devices are HP iPaq handhelds, although if time permits we will alsoinvestigate a cellphone platform that uses a reduced version of the Linux operatingsystem. The experiment will be to demonstrate virtualization of a handheld node thatallows it to be used as a MANET (i.e., as a packet relay) concurrently with its use as aVoIP edge device. The performance will be evaluated using the e-Model for voicequality. Maintaining voice quality will demonstrate the effectiveness of the resourcemanagement and isolation.

移动的计算和无线电话正在日益融合，许多手持设备（例如，PALMTreos和RIM黑莓）能够承担的角色，无论是作为蜂窝电话或计算机。一个关键的研究问题，出现了这种融合的后果是，是否策略，如虚拟化用于隔离和资源共享的大型有线计算机将适用于机器的大小，计算能力和电池寿命的限制。这个问题也对NSF提出的GENI计划影响最多的网络端点（例如，有超过20亿的GSM移动的电话在使用）的程度有很大的影响。该项目集中在一项实验性的工作上，以预测这种需求，并为手持设备中的资源划分和隔离问题提供一个明确的答案。我们的候选设备是HP iPaq手持设备，但如果时间允许，我们也将研究一种使用简化版Linux操作系统的手机平台。该实验将演示手持节点的虚拟化，使其能够用作MANET（即，作为分组中继），同时将其用作VoIP边缘设备。将使用e-Model对性能进行评估，以确定是否满足要求。保持语音质量将证明资源管理和隔离的有效性。
