A transport protocol to improve access to data networks from GSM using a proxy

چکیده
In order to access TCP/IP networks (mainly the Internet) through GSM links,. we have designed an architecture based in the indirect model of client/server interaction, where an intermediate element acts as a bridge between GSM and the rest of the data network. We have replaced the TCP connection in the client-proxy link with a simpler protocol. This allows maintaining the protocols in server machines, and requires minimal changes in those running in the mobile clients. In this paper we describe STP protocol and present some measurements of the performance obtained with it, compared to conventional TCP/IP architecture and a sort of indirect TCP based architecture. The obtained results show that our approach improves the performance achieved with conventional TCP/IP and indirect TCP, while maintaining a high level of application compatibility.

A TESLA-based mutual authentication protocol for GSM networks
The widespread use of wireless cellular networks has made security an ever increasing concern. GSM is the most popular wireless cellular standard, but security is an issue. The most critical weakness in the GSM protocol is the use of one-way entity authentication, i.e., only the mobile station is authenticated by the network. This creates many security problems including vulnerability against m...

متن کاملMulti-channel Medium Access Control Protocols for Wireless Sensor Networks: A Survey
Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...

متن کاملPerformance Improvement of Expanded Integrated Local Area Networks (RESEARCH NOTE)
In Local Area Networks (LAN) connected together by bridges, flow control and smooth traffic in the network is very important. However, congestion at bridges can cause intensive loss of received frames. In addition, the received frames are thrown away and have to be retransmitted by the source station, which causes more congestion and massive reduction in the overall network throughput. The netw...
