We discuss the architectural and management support of real time data streams, both in terms of lower level messaging and higher level service, filter and session structure. Our messaging system acts as a substrate that can be used to provide qualities of service to various streaming applications ranging from audio-video collaboration systems to sensor grids. The messaging substrates are compos...

While instant messaging (IM) became a mature communication means in business organizations over the last years, IM systems did not follow this evolution comparably. Communicated content is often stored insufficiently and hard to recall, integration into other desktop applications impossible. In this paper, we address these shortcomings and provide concepts for novel instant messaging. In contra...

Instant Messaging is traditionally a text only affair. However, there are instances when it would be useful to bridge to other types of media, like speech. The SoftBridge is an application framework that enables this kind of communications bridging using instant messages. Its use of protocols like the Jabber Instant Messaging Protocol and the Simple Object Access Protocol makes it simple, open ...

Generally, Stereo image is composed of two stereoscopic images in such way that gives three dimensional affect when viewed. GSM have two short messaging services, which can transfer images and sounds etc. Such services are known as; MMS (Multimedia Messaging Service) and EMS (Extended Messaging Service). EMS can se...

Multimedia messaging service (MMS) promises a dramatic increase in messaging capabilities for mobile phone users that will enrich their experience. For network operators and content and service providers, it will create a major new source of revenue because it adds features such as color pictures, animations, audio samples, and video clips. However, the current MMS standard provides only a few ...

Spatial messaging is a term that defines the virtual publication of data in physical places. Anyone in the neighborhood of such a publication point gets the message. Architectures allowing users to publish freely spatial messages already exist. However, experiences realized with volunteers showed that there is only little interest in posting such notes. To our view, the main reason is that ther...

Mobile messaging started with Short Messaging Service (SMS). Multimedia Messaging Service (MMS) was recently introduced, allowing users to send and receive messages composed of text, audio, images and even movie clips. In this paper, we propose a new step in the evolution of mobile messaging by introducing the Annotated Multimedia Messaging Service (AMMS). AMMS is in short an MMS document augme...

TinyOS 2.x supplies a well-designed single hop messaging layer for applications, but there is no standardized multihop framework. To address this issue, we surveyed a large number of applications [1] to determine the addressing techniques and messaging stack features used in sensor networks. From the results of this survey, we designed a multihop networking API [2] to address the needs of appli...
