Current Internet transports conflate transport semantics with endpoint addressing and flow regulation, creating roadblocks to Internet evolution that we propose to address with a new layering model. Factoring endpoint addressing (port numbers) into a separate Endpoint Layer permits incremental rollout of new or improved transports at OS or application level, enables transport-oblivious firewall...

A new modular transport layer protocol for wireless sensor networks (WSNs) is proposed: WMTP – Wireless Modular Transport Protocol. This protocol not only allows the simultaneous use of all the main features commonly found in WSN transport protocols, namely congestion control, fairness, and reliability, but also does so in a modular fashion. This way, the application layer can choose to use exa...

Various cooperative applications have been developed like shared editors, teleconferences, and more generally multimedia applications. These applications are based on similar mechanisms. This paper presents a model of cooperation based on two layers. The application layer uses the services provided by the cooperative layer regardless what type of application is used. Some common points and thei...

With the population of an internet telephony, the security issues of a SIP application service is focused on, currently. For example, VoIP is easier to access than existing PSTN, and more exposed at many security threats. However, there is not enough monitoring and attack detecting devices, yet. In this paper, we propose analysis factors, a detection example to use it and required collecting in...

The level set approach can be used as a powerful tool for 3D segmentation of a tumor to achieve an accurate estimation of its volume. A major challenge of such algorithms is to set the equation parameters, especially the speed function. In this paper, we introduce a threshold-based scheme that uses level sets for 3D tumor segmentation (TLS). In this scheme, the level set speed function is desig...

In an attempt to better understand the current transportation situation in Santiago de Chile, this paper provides a framework within which persona1 expenditures, environmental consequences and social effects can be measured by a common metric, costs. The analysis includes all modes of transport, but has a specific focus on passenger transport modes. The paper presents the cost categories consid...

The MultiMedia Multi-Channel Infrastructure shall enable the development of multimedia services which can be deployed across multiple devices. The platform functions as a springboard for the prototyping of new products and services relevant to both industrial and public sectors. The infrastructure consists of all generic mechanisms needed by di erent applications. This makes the development of ...
