چکیده

Distributed TCP Caching (DTC) substantially improves TCP performance in wireless sensor networks. We study DTC performance gains with two link layer error control mechanisms, namely link layer retransmissions and forward error control. Our results suggest that applying forward error correction to TCP acknowledgements is the best choice for our ongoing real implementation of DTC.

Distributed TCP Caching for Wireless Sensor Networks

Many applications of wireless sensor networks are useful only when connected to an external network. Previous research on transport layer protocols for sensor networks has focused on designing protocols specifically targeted for sensor networks. The deployment of TCP/IP in sensor networks would, however, enable direct connection between the sensor network and external TCP/IP networks. In this p...

Performance Evaluation of DTSN in Wireless Sensor Networks

The guaranteed delivery of critical data is an essential requirement in most Wireless Sensor Network (WSN) applications. The paucity of energy, communication, processing and storage resources in each WSN node causes the TCP transport model (widely used in broadband networks) to be inefficient in WSNs, a reason why new WSN-specific reliable transport protocols have been proposed in the past few ...

Object Caching in a Transactional, Object-Relational CORBA Environment

The OMG's CORBA and CORBA services like the OTS are a technology standard that enable the building of transactional systems running in distributed and heterogeneous environments. In large-scale CORBA systems that integrate relational databases, however, careful attention must be paid to network traffic and the number of I/O-operations (like database access) performed, as these can degrade syste...

Design of Object Caching in a CORBA

CORBA Object Transaction Monitors (OTM) refer to a mid-dleware technology that enable the building of transactional, object-oriented information systems running in distributed and heterogeneous environments. In this paper, we address large-scale OTM-based systems and focus attention on the important quality factors of system performance , system scalability, and system reliability. We develop a...

Caching Based Transport Optimization for Wireless Multimedia Sensor Networks

Traditional transport layer protocols have been designed to perform end-to-end error control transparently to the intermediate nodes (e.g., TCP). To address the severe resource constraints featured by Wireless Sensor Networks (WSN), new paradigms have been developed such as intermediate caching where intermediate nodes are able to cache packets and if possible retransmit them on-demand to avoid...
