普适计算涉及各种实体，它们需要通过不同的服务发现协议来协调任务和共享资源。然而，这些协议的多样性和不兼容性使互联互通成为问题。此外，大多数服务发现协议需要用户的强烈参与才能真正发挥作用。因此，在普适环境中的服务发现已成为研究人员以及从业者试图通过各种方法来克服的挑战。然而，现有的解决方案主要包括设计新的协议，通常解决特定的应用需求，同时参与增加的异构性。
为了解决这些问题，我们提出了一个新的范式服务发现涉及使用的网关，称为UbiGate，并依赖于SIP，一个广泛的信令协议。UbiGate围绕存在的概念，在隐藏底层协议的异构性的同时，实现了服务信息的真实的时间可用性。我们已经开发了一个原型的UbiGate支持服务发现协议，如在蓝牙服务发现机制中使用的协议和协议，使RFID的检测机制。初步结果表明，UbiGate使新的服务发现协议，无论是基于IP或非IP，以无缝支持没有显着的开销在发现延迟。
Pervasive computing involves various entities which need to coordinate tasks and share resources through different service discovery protocols. However, the multiplicity and the incompatibility of those protocols have made interconnectivity problematic. Moreover, most service discovery protocols require a strong participation of users to genuinely play their part. Consequently, service discovery in a pervasive environment has become a challenge that researchers as well as practitioners have tried to overcome through various approaches. Nevertheless, existing solutions mostly consist of designing new protocols which usually address specific application needs while participating in the increase of heterogeneity.
To address these problems, we present a new paradigm for service discovery involving the use of a gateway, called UbiGate, and relying on SIP, a widespread signaling protocol. Centered around the notion of presence, UbiGate enables real time availability of service information while hiding the heterogeneity of underlying protocols. We have developed a prototype of UbiGate supporting service discovery protocols such as the protocol used in Bluetooth service discovery mechanism and a protocol enabling the detection mechanism of RFID. Preliminary results show that UbiGate enables new service discovery protocols, either IP or non-IP based, to be seamlessly supported with no significant overhead in discovery latency.
