Transmission Control Protocol for Wireless Networks
Transmission control protocol or (TCP) is used purposely for data transfer over the internet. The main strength on this protocol is its ability to make use of flow control algorithm which allows TCP to decrease the rate at which data is sent when congestion in the network occurs. For this particular paper, research will be carried out to find out how TCP can transmit data for wireless networks.
This research is carried out since TCP was originally designed for networks that had wired links and carried stationary hosts. However, there has been an increase in the use of wireless networks, which present a whole new set of diverse characteristics different from the wired networks. This is because wireless networks are characterized by wireless links and hosts that are mobile with a very bit error rate of BER 10-2 to 10-4 as compared to the fiber link of 10-9 (Chan, Tsang & Gupta, 1997). These high bit error rates have been known to cause, packet errors that cause false alarms and which, cause unnecessary congestions, back-off in retransmission time at the host. This error is also associated with mobility and signal fading, associated with non-congestive and congestive losses as defined by (Leung & Li, 2006). Therefore, this research seeks to find current information on how TCP is calibrated and enhanced to address the problem of congestion and packet losses for wireless networks. This is based on the fact that current communication systems are being faced by wireless applications like high speed multimedia and wireless communication platforms carried by the internet (Tian, Xu & Ansari, 2005).
The Transmission Control Protocol for the internet was created by American department of defense, under the body, Advanced Research Projects Agency Network (ARPANET) (Leung & Li, 2006). ARPANET made use of the packet switching technology to send data, and consequently under Request for Comment or RFC 793, TCP was created, while RFC 791 created IP in 1981, by the Internet Engineering Task force of IEFT (Tian, Xu & Ansari, 2005). APRANET built TCP in the many layers of the open system interconnection or the OSI. TCP was created as a protocol in the layer four transport systems, which uses the fundamental IP services to give applications on a connection that is end-to-end, for data delivery (Tian, Xu & Ansari, 2005).
Originally, ARPANET created TCP purposely for wired networks. In these networks, there is negligible BER and congestion which were cited as the major causes of packet loss (Tian, Xu & Ansari, 2004). This protocol implements packet flow through flow and congestion control algorithms which are founded on additive multiplicative decrease or (AIMD) and sliding window algorithms (Tian, Xu & Ansari, 2004). The purpose of the sliding window is to offer a control mechanism which allows a sender to send a transmission window when they receive an acknowledgement (ACK) which indicates the last packet which is in in-order, as received successfully by the receiver (Tian, Xu & Ansari, 2004). In cases, where packets are lost due to congestion caused by buffer ove...
