“…In contrast, ad-hoc networks are multi-hop networks in which data have to be transmitted over several wireless links, from the sender to the receiver [11]. Recently, new solutions have been proposed [14], [15], [17] in the case of ad hoc networks, most gives good result but not accurate enough, therefore new research have been proposed to give satisfactory results.…”

We present in this paper a novel approach to improve TCP performance in the mobile wireless networks (MANET). The proposed protocol, designated as HYBRID TCP, is essentially an extension of the original IEEE 802.11 standard and the TCP-Reno protocol. By making some modifications using a cross layer solution to the legacy IEEE 802.11 MAC and TCP-Reno protocol, HYBRID TCP provides a significant improvement in the performance of TCP in multi-hop wireless environments by taking in consideration the mobility of nodes, the interferences and solves the problem of multi-hops. The performance of HYBRID TCP is compared to that of standard TCP-Reno scheme and to a recent improvement of TCP performed on the basis of the signal strength in terms of achieved effective throughput and of transmission time. The numerical results reveal that HYBRID TCP achieves a significant improvement in the TCP transmission performance over mobile multi-hop wireless networks.

“…In [24], the timeout is updated using link layer feedback from the receiver and a retransmission is performed if necessary. In [25], the retransmission priorities and the maximum number of retransmission are determined considering the TCP timing information gathered from the transport layer. Lastly, cross layer ARQ that eliminates sending TCP ACKs from the receiver was proposed in [26][27][28].…”

The IEEE 802.16j Mobile Multihop Relay (MMR) WiMAX network allows the number of hops between the end user and the base station to be more than two hops. It supports non-real-time Polling Service, which considers the minimum reserved rate and the maximum sustained rate as a QoS requirements. The reliability of sending the data over MMR WiMAX is achieved by using Transmission Control Protocol (TCP) in transport layer and automatic repeat request in the link layer. However, the use of automatic repeat request in the link layer makes the round trip time fluctuate rapidly, which increases the possibility of retransmission timeout (RTO) expiration. TCP performance degrades because of frequent timeout, and hence the QoS transmission rates cannot be satisfied. Therefore, this paper presents an RTO smoothing scheme and QoS aware transmission control to enhance the performance of data transmission over MMR WiMAX networks. The RTO smoothing scheme aims to reduce the frequent timeout occurrences. The slow start threshold and maximum congestion window are adjusted to satisfy the required QoS and it provides transmission rate fairness for the users at different hops. The results showed that, the proposed schemes reduce the timeout, and improve the utilization of the allocated resources and TCP throughput.

“…The method of researching in computer network based on the ТСР/IР protocol requires determine the most effective topology structure, within the framework of which maximum burst performance can be achieved from managing the modes of data exchange. The decision touches topology of the network of which lies the network characteristic [2,4,12]. The following variants of local Area Network structure are possible from the proposed methods:  Bus or star network type for small or medium Local Area Networks;  Difficult network for medium and large or complex Corporate Networks.…”

“…The mode of operations in distributed computer networks affected by the critical level of workload which is corresponds to the "bottleneck" of the network, results into degradation of bandwidth capacity of the network [11,12,13]. The variants of chosen network structure on the second stage of the network execution sequence in the methodology are explored by using simulation technique of NetCracker® Professional package.…”

Rapid developments in communication and information technologies and the ever growing network user's demands have made network traffic efficiency a prominent problem in today's internet. As users come and go, so do the packets they send: Internet performance is therefore largely governed by these inevitable natural fluctuations, it is therefore of great importance to develop more advanced as well as robust methodologies and models to deliver manageable, stable and reliable services in order to fulfill the ever-growing demands for the QoS requirements in the networks. The basic task of research and simulation of network infrastructure is to work out the recommendations for the most rational use of computer network resources. The necessity herein arises upon both at development of new network application and deployments, and also, during administration or development of the existing networks. This paper, therefore, presents a new method of boosting data exchange efficiency using developed multi-layer simulation models to suite any network traffic with samples.
