TCP - IP White Papers

Improvement of TCP Throughput by Combination of Data and ACK Packets in Ad Hoc Networks

Tags:
tcp - ip

Overview Since a radio channel is shared among terminals in an ad hoc network, packet collisions are frequent. In case of transmitting packets especially using TCP, data and ACK packets are transmitted in opposite directions on the same radio channel. Therefore, frequent collisions are unavoidable, and this seriously degrades TCP throughput. It is possible to transmit to two or more nodes which adjoin from a certain node simultaneously on the radio channel. To reduce the likelihood of packet collisions when an intermediate node transmits both data and ACK packets, these two types of packet can be combined and transmitted at the same time to increase the efficiency of radio channel utilization.

GPRS networks lose 43 per cent of data

Up to 43 per cent of data packets got lost on the way from the radio terminal to the mast, and the latency - or the delay between a request and a response - was up to five seconds. Their surveys of radio networks showed that while GPRS coverage is...

Where is the mysterious internet code coming from?

While such an internet address in the source field of a data packet will often be transmitted by less vigilant internet service providers, almost no provider would forward data that had such an address in the destination field.

Secure VoIP has arrived

TCP uses packet retransmission, which means that packets can be delayed en route to their destination. The Net6 device sends false TCP acknowledgements so that the sender continues sending packets. Murli Thirumale, Net6's chief executive officer...

VoIP primer: How it works - and what the jargon means

The packets that make up the audio stream may take different routes from node to node over the network in question but and are put back into order at the termination point to make up the audio that we recognise as conversation.

Wi-Fi chipmakers get together for 300Mbps+

Mimo works by allowing two or more distinct signals to be transmitted over the same 802.11 radio channel at the same time with no interference. The new standard is likely to be based on a technology called multiple-input/multiple-output, or Mimo...

Radioactive: Today a jam, tomorrow the open road?

What's unique about the car-to-car initiative is that it relies on very little fixed infrastructure: instead of a car connecting to an IP cloud, it is essentially a node on a network of other cars, fully meshed with other cars in close proximity.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
