TCP ISSUES IN MOBILE ADHOC NETWORKS: Challenges and Solutions
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 1
Abstract
Abstract: The transmission control protocol (TCP) is the most predominant transport layer protocol in the Internet today. It transports more than 90% percent of the traffic on the Internet. Its reliability, end-to-end congestion control mechanism, byte-stream transport mechanism, and, above all, its elegant and simple design have not only contributed to the success of the Internet, but also have made TCP an influencing protocol in the design of many of the other protocols and applications. Its adaptability to the congestion in the network has been an important feature leading to graceful degradation of the services offered by the network at times of extreme congestion. TCP in its traditional form was designed and optimized only for wired networks. This protocol is mainly known because of its feature of providing reliable delivery of packets from source to destination. In TCP, reliability is achieved by retransmitting lost packets. Since TCP is widely used today and the efficient integration of mobile adhoc networks (MANETs) with the Internet is paramount wherever possible, it is essential to have mechanisms that can improve TCP's performance in MANETs. In this paper, we describe the challenges of standard TCP in MANETs. We also proposed some techniques to improve TCP performance, advantages and disadvantages of the proposed techniques.
