This project aims to develop two new smartphone-based infrastructure models to support applications that require interaction and communication in the proximity without the support of the Internet. It is motivated by the fact that ad-hoc networks formed by a collection of smartphones can help improve the current location-based services, propel new applications, and enhance the wireless infrastructures. In this project, one model harnesses the heterogeneous radio interfaces to improve bulk data transfer while the other model explores a new passive communication approach for disseminating short messages such as Tweets and Facebook messages. Both new models target on reducing the energy cost and network overhead which are critical to deploying smartphone ad-hoc networks. If successful, this project will result in two new mobile ad-hoc network architectures and a suite of protocols built on them. It is expected to have immediate impact on the research community and industry. The results of this project will further broaden the mobile application scope and may inspire developers to create innovative services based on local data communication.Specifically, this project addresses the high-cost issue in path establishment and path recovery in traditional mobile ad-hoc networks. The first new model integrates a long-range radio into a smartphone to carry out control and management packets while payload data are still transferred over regular radios such as WiFi and Bluetooth. A new routing protocol will be developed based on this dual radio setting to improve the efficiency. The second new model uses the mandatory 'peer discovery' function in Bluetooth and WiFi-Direct protocols to disseminate short messages among the smartphones in the proximity. The cost for establishing and maintaining wireless links is negligible, and the feature of fetching messages from multiple nearby devices is desirable for the applications that spread messages in the proximity. This project will develop an appropriate strategy for each smartphone to receive and dispatch messages with the objective of conserving the energy cost and improving the message delivery ratio.

该项目旨在开发两个新的基于智能手机的基础架构模型，以支持需要在不支持Internet的情况下接近互动和通信的应用程序。这是由于智能手机集合形成的临时网络可以帮助改善当前基于位置的服务，推动新应用程序并增强无线基础架构。在这个项目中，一个模型利用了异质的无线电接口来改善批量数据传输，而另一种模型则探索了一种新的被动通信方法，用于传播短消息，例如推文和Facebook消息。两种新模型都针对降低能源成本和网络开销，这对于部署智能手机临时网络至关重要。如果成功，该项目将导致两个新的移动临时网络体系结构和一套在其上构建的协议。预计它将立即对研究社区和行业产生影响。该项目的结果将进一步扩大移动应用程序范围，并可能激发开发人员基于本地数据通信创建创新服务。特别是，该项目解决了传统移动临时网络中路径建立和路径恢复中的高成本问题。第一个新模型将远程收音机集成到智能手机中，以执行控制和管理数据包，而有效载荷数据仍在常规的无线电上（例如WiFi和蓝牙）传输。将根据此双收音机设置开发新的路由协议，以提高效率。第二个新模型在蓝牙和wifi-direct协议中使用强制性的“同伴发现”功能，以在接近度中的智能手机之间传播短消息。建立和维护无线链接的成本可以忽略不计，并且希望从附近设备中获取消息的特征对于在接近性中传播消息的应用是可取的。该项目将为每个智能手机接收和派遣消息制定适当的策略，目的是保留能源成本并提高消息传递比率。
