In a mobile ad hoc network, the data packet may fail to be delivered for various reasons mostly for route failure, congestion and battery energy drain. Hence, providing reliable and timely data delivery in this network in an energy-efficient way is challenging. Although there exist several solutions to solve these problems, they can handle either route failure or congestion or energy-efficient ...

Increase demand by all and sundry for internet and share network, has enhanced the development of various network technology that has linked together different people of different motives, consequently it has paved way for malicious and unauthorized user to intrude into information resources of organization. As a result of the advantage embedded in the layered framework and those of signature b...

Different from the traditional wired network, the fundamental cause of transmission congestion in wireless ad hoc networks is medium contention. How to utilize the congestion state from the MAC (Media Access Control) layer to adjust the transmission rate is core work for transport protocol design. However, recent works have shown that the existing cross-layer congestion detection solutions are ...

With the network architecture more and more complex, it is an interesting problem how to cooperate many routers working in the multilayer network simultaneously. Since these AQM (Active Queue Management) algorithms based on the single router have not considered the link capacity of connected routers, there are some disadvantages, e.g., it is difficult to deal with the congestion problem effecti...

Reliable network connectivity in wireless sensor networks (WSN) is difficult to achieve. Harsh, unattended, low-security environments and resource-constrained nodes exacerbate the problem. An ability to detect connectivity disruptions, due to either security or environmental problems, allows WSN to conserve power and memory while reducing network congestion. We propose RE-CD, an integrated solu...

We’ve been developing a sensor that can acquire positional data. Recently, a position-based big data creation is easy task and trajectory analysis is the highest priority for ”position-based service”. Traffic congestion, marketing mining, and pattern analysis are the one of the examples in trajectory analysis field. In this paper, we propose the trajectory analysis approach for clustering and a...

We introduce a receiver-oriented approach to congestion control, demonstrated by an experimental protocol, TCPReal. The protocol allows for a measurement-based transmission strategy, which complements the ‘‘blind’’ increase/ decrease window adjustments. Owing to its design, the protocol displays an inherent property to produce comprehensive dynamics in heterogeneous environments with wired or w...

as wireless networks with high data rate get widely deployed, improving the performance of tcp over these networks plays vital role. wireless link losses have dramatic adverse impact on tcp performance due to the difficulty in distinguishing the congestion losses from wireless link losses. we first, studied the various existing bandwidth estimation algorithms over the wireless networks. in this...

This paper presents a new active queue management scheme, Fuzzy Explicit Marking (FEM), implemented within the differentiated services (Diff-Serv) framework to provide congestion control using a fuzzy logic control approach. Network congestion control remains a critical and high priority issue. The rapid growth of the Internet and increased demand to use the Internet for timesensitive voice and...

Since from last decade, there is tremendous growth in cellular wireless networks like heterogeneous cellular networks. The heterogeneous networks such as LTE-A in which WiFi, WiMAX networks are communicated frequently. Radio Access Technologies (RATs) through which number of mobile devices having interfaces, similarly mobile devices having number interfaces with different RATs. These RATs are d...
