Abstract
Transmission Control Protocol (TCP) is the most important transport layer protocol being used nowadays. It suffers from many problems over mobile networks especially over Cognitive Radio (CR). CR is one of the latest mobile technologies that brings its own share of problems for TCP. The buffer overflow for CR secondary network relay node can affect the performance of TCP. The contribution of this paper is the novel cross-layer model being used to evaluate the effect of the TCP congestion control on the secondary relay node buffer size in Cognitive Radio Network (CRN). The performance has been assessed by buffer overflow probability.
Highlights
Transmission control protocol (TCP) [1] is the most famous transport protocols that provides a connection which is oriented and reliable end-to-end services with the help of its flow and congestion control mechanisms
This paper studies the cross-layers interaction between TCP behaviour and relay node buffer overflow
Numerical results are presented to evaluate the effect of TCP parameters on buffer overflow
Summary
Transmission control protocol (TCP) [1] is the most famous transport protocols that provides a connection which is oriented and reliable end-to-end services with the help of its flow and congestion control mechanisms. When the loss is detected via timeout, ACKs still arrive at the source and losses can be recovered without slow start by using several TCP congestion algorithms like Reno [4], New Reno [5], SACK [6], and Vegas [7] that call a fast recovery algorithm. This algorithm ends and normal congestion avoidance algorithm is called Some of these CRNs unique features are primary users (PUs) arrivals, spectrum sensing, spectrum changing, and heterogeneous available channels in secondary users (SUs). It is well-known that TCP has a degraded throughput under wireless systems especially with a high packet loss rate [8].
