Optical transmittance based store and forward routing in satellite networks

Routing in Turn-Prohibition Based Feed-Forward Networks

The application of queuing theory to communications systems often requires that the respective networks are of a feed-forward nature, that is they have to be free of cyclic dependencies. An effective way to ensure this property is to identify a certain set of critical turns and to prohibit their use. A turn is a concatenation of two adjacent, consecutive links. Unfortunately, current routing al...

Static Flow Control in Store-and-Forward Computer Networks

In this paper we develop an analytic model for end-to-end communication protocols and study the window mechanism for flow control in store-and-forward (in particular message-switching) computerbased communication networks. We develop a static flow control model in which the parameters of the system are not dynamically adjusted to the Paper approved by the Editor for Computer Communication of th...

A QoS-based Routing Algorithm in Multimedia Satellite Networks

Real-time multimedia applications impose strict delay bounds and are sensitive to delay variations. Satellite link handover increases delay jitter and signaling overhead as well as the termination probability of ongoing connections. To satisfy the QoS requirements of multimedia applications, satellite routing protocols should consider link handovers and minimize their effect on the active conne...

Rural Telemedicine Networks Using Store-and-Forward Voice-over-IP

Store and forward Voice-over-IP is a suggested solution for supporting Telemedicine at rural health clinics in developing countries. Solutions described to date are designed to support communication by establishing point-to-point connectivity between two sites. In this paper we present an approach for creating scalable Telemedicine networks based on Delay Tolerant Networking. This holds potenti...
