TLDR
This paper examines with simulations the performance of TCP over GPRS and it is shown that both TCP and G PRS are well harmonised.Abstract:
GPRS is the new packet-oriented data service for GSM. Soon it will be possible to take advantage of the features provided by GPRS for Internet access like fast connection set-up, volume-based charging and staying on-line for long periods. For non-real-time Internet applications TCP is the applied transport protocol. Often it was suspected that GPRS introduces severe performance degradations for TCP traffic since both apply their own ARQ mechanism. It is well known that layered protocol interactions can have very negative influences. This paper examines with simulations the performance of TCP over GPRS. The behaviour of the protocols is analysed under various conditions. It is shown that both TCP and GPRS are well harmonised.read more

Delay/Fault-Tolerant Mobile Sensor Network (DFT-MSN): A New Paradigm for Pervasive Information Gathering
TL;DR: An optimized flooding scheme that minimizes transmission overhead in flooding is introduced and two simple and effective DFT-MSN data delivery schemes are proposed, namely, the replication-based efficient data delivery scheme (RED) and the message fault tolerance-based adaptive data Delivery scheme (FAD).

A large-scale, passive analysis of end-to-end TCP performance over GPRS
TL;DR: A passive methodology for TCP performance evaluation over general packet radio service (GPRS) networks is presented that relies on traffic monitoring at the GPRS ingress/egress router interface to analyze TCP performance and demonstrate the applicability of the method.

TL;DR: This work shows how current TCP implementations introduce unacceptably long pauses in communication during cellular handoffs, and proposes an end-to-end fast retransmission scheme that can reduce these pauses to levels more suitable for human interaction.

Improving wireless LAN performance via adaptive local error control
TL;DR: It is argued and demonstrated that protocol-independent link-level local error control can achieve high communication efficiency even in a highly variable error environment, that adaptation is important to achieve this efficiency, and that inter-layer coexistence is achievable.
