Book excerpt: Thesis (M.A.) from the year 2019 in the subject Engineering - Computer Engineering, , language: English, abstract: The digital era of communications shapes the globe from wired networks to wireless network, offline media to online media. The mobile adhoc network is one of the major categories of network where the users depends upon and accessing the services too. As the number of users increases in accessing the data in mobile adhoc networks, the major challenging issue is congestion. The type of data transmitting and receiving in mobile adhoc networks mainly deals with multimedia data i. e audio, video and animations. The bandwidth utilization is high in case of multimedia data in the mobile ad hoc network when compared to other data payloads. The network performance level can be optimized by reducing the congestion in mobile adhoc networks. It is highly difficult to provide best performance to meet the user expectations in mobile adhoc networks. As in mobile adhoc network, Congestion control at the transport layer is the greater role. Subsequently, the various compound designs are being used and system which has to adjusted as per the service providers. As Quality of Service is very much required by users in mobile adhoc networks and it’s very much problematic to attain them by having a less number of resources. TCP is the standard protocol of transport layer which behaves in different flavors. Among such variants NewReno and HSTCP are the most commonly used. However the performance of TCP NewReno and HSTCP are very much sensitive to immediate changes in the traffic load. For achieving the QoS in mobile adhoc networks the problems related with congestion issues has to be addressed. The proposed work identifies certain number of issues during the improvement of QoS in mobile adhoc networks. Hence, the proposed algorithms MHSTCP and SwTCP are designed and developed. MHSTCP and SwTCP give attention towards few parameters such as Bandwidth utilization, Data rate, Delay, and energy. The proposed algorithms are simulated in Network Simulator-2 by varying impairments and results are verified. Based on the simulation results, the research outcome shows that the proposed algorithms outperform the existing TCP congestion control variants in enhancing the QoS parameters in Mobile adhoc networks.

Download or read book Congestion Control in Data Transmission Networks written by Przemysław Ignaciuk and published by Springer. This book was released on 2012-08-01 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Congestion Control in Data Transmission Networks details the modeling and control of data traffic in communication networks. It shows how various networking phenomena can be represented in a consistent mathematical framework suitable for rigorous formal analysis. The monograph differentiates between fluid-flow continuous-time traffic models, discrete-time processes with constant sampling rates, and sampled-data systems with variable discretization periods. The authors address a number of difficult real-life problems, such as: optimal control of flows with disparate, time-varying delay; the existence of source and channel nonlinearities; the balancing of quality of service and fairness requirements; and the incorporation of variable rate allocation policies. Appropriate control mechanisms which can handle congestion and guarantee high throughput in various traffic scenarios (with different networking phenomena being considered) are proposed. Systematic design procedures using sound control-theoretic foundations are adopted. Since robustness issues are of major concern in providing efficient data-flow regulation in today’s networks, sliding-mode control is selected as the principal technique to be applied in creating the control solutions. The controller derivation is given extensive analytical treatment and is supported with numerous realistic simulations. A comparison with existing solutions is also provided. The concepts applied are discussed in a number of illustrative examples, and supported by many figures, tables, and graphs walking the reader through the ideas and introducing their relevance in real networks. Academic researchers and graduate students working in computer networks and telecommunications and in control (especially time-delay systems and discrete-time optimal and sliding-mode control) will find this text a valuable assistance in ensuring smooth data-flow within communications networks.

Download or read book Ad Hoc and Sensor Networks written by Carlos de Morais Cordeiro and published by World Scientific. This book was released on 2011 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive yet easy coverage of ad hoc and sensor networks and fills the gap of existing literature in this growing field. It emphasizes that there is a major interdependence among various layers of the network protocol stack. Contrary to wired or even one-hop cellular networks, the lack of a fixed infrastructure, the inherent mobility, the wireless channel, and the underlying routing mechanism by ad hoc and sensor networks introduce a number of technological challenges that are difficult to address within the boundaries of a single protocol layer. All existing textbooks on the subject often focus on a specific aspect of the technology, and fail to provide critical insights on cross-layer interdependencies. To fully understand these intriguing networks, one need to grasp specific solutions individually, and also the many interdependencies and cross-layer interactions.

Download or read book Guide to Wireless Sensor Networks written by Sudip Misra and published by Springer Science & Business Media. This book was released on 2009-05-29 with total page 725 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overview and Goals Wireless communication technologies are undergoing rapid advancements. The last few years have experienced a steep growth in research in the area of wireless sensor networks (WSNs). In WSNs, communication takes place with the help of spatially distributedautonomoussensornodesequippedtosensespeci?cinformation. WSNs, especially the ones that have gained much popularity in the recent years, are, ty- cally, ad hoc in nature and they inherit many characteristics/features of wireless ad hoc networks such as the ability for infrastructure-less setup, minimal or no reliance on network planning, and the ability of the nodes to self-organize and self-con?gure without the involvement of a centralized network manager, router, access point, or a switch. These features help to set up WSNs fast in situations where there is no existing network setup or in times when setting up a ?xed infrastructure network is considered infeasible, for example, in times of emergency or during relief - erations. WSNs ?nd a variety of applications in both the military and the civilian population worldwide such as in cases of enemy intrusion in the battle?eld, object tracking, habitat monitoring, patient monitoring, ?re detection, and so on. Even though sensor networks have emerged to be attractive and they hold great promises for our future, there are several challenges that need to be addressed. Some of the well-known challenges are attributed to issues relating to coverage and deployment, scalability, quality-of-service, size, computational power, energy ef?ciency, and security.
