This project generates communication solutions that support adaptive applications by tightly integrating context-awareness and communication. Specifically, the project focuses on providing efficient context sensing solutions and adaptive application-aware communication. A significant drawback of existing context sensing approaches is that they require additional network communication to generate reliable measures of context. This project develops passive context sensing, in which information about the state of the environment is inferred using information already known to communication protocols. To use this passive context sensing to enable adaptive application-aware communication, the project incorporates context information into communication protocols alongside application requirements to dynamically change the behavior and subsequently the effectiveness of particular communication protocols. Specifically, the approach dynamically adjusts the reactivity and proactivity of a dynamic routing protocol to account for changing context properties. When the overhead of gathering information for adaptation can be kept to a minimum, the benefits received from adaptation can be great. It is exactly this design point that this project exploits: reducing the overhead of collecting context information to near zero maximizes the payoffs adaptive communication protocols can achieve.Broader Impact: The fact that the project's work revolves around pervasive computing makes it especially accessible and exciting to students and the public. Specific outreach activities will include not only university students but local middle and high school students and community members through university supported programs.

该项目生成通信解决方案，通过紧密整合上下文意识和沟通来支持自适应应用程序。 具体而言，该项目致力于提供有效的上下文感测解决方案和自适应应用感知的通信。 现有上下文感测方法的一个重要缺点是，它们需要其他网络通信来生成可靠的上下文度量。 该项目开发了被动上下文感测，其中使用通信协议已知的信息来推断有关环境状态的信息。 要使用这种被动上下文感测来启用自适应应用程序感知通信，该项目将上下文信息与应用程序要求一起将上下文信息纳入了应用程序，以动态地改变行为，并随后更改特定通信协议的有效性。 具体而言，该方法会动态调整动态路由协议的反应性和主动性，以解释上下文属性的变化。 当收集适应信息的收集信息的开销可将其保持在最低限度时，从适应中获得的好处可能会很大。 正是这个项目的利用是：将收集上下文信息收集上下文信息的间接开销最大化的收益最大化自适应通信协议可以实现的回报。Broader的影响：该项目的工作围绕普遍计算而旋转的事实使其对学生和公众特别易于访问且令人兴奋。 特定的外展活动将不仅包括大学生，而且包括当地的中学和高中生和社区成员，并通过大学支持的计划。
