商品描述

A large portion of the network capacity of an ad hoc network can be wasted by the medium access mechanisms of omni-directional antennas. To overcome this problem, researchers propose the use of directional or adaptive antennas that largely reduce radio interference, improving the utilization of wireless medium and the resulting network throughput.

Enhancing the Performance of Ad Hoc Wireless Networks with Smart Antennas discusses these issues and challenges. Following an introduction to ad hoc networks, it presents an overview of basic Media Access Control (MAC) and routing protocols in ad hoc networks with omni-directional antennas. The book then focuses on the use of smart antennas in ad hoc networks and reviews the strategies used in designing MAC and routing protocols for improved medium utilization and improved routing performance with effective load balancing. Finally, it analyzes the design issues related to priority based quality-of-service (QoS) routing protocols, illustrating the potential of these antennas in comparison to omni directional antennas. The book concludes with an examination of open problems and challenges for ad hoc networks.

商品描述(中文翻譯)

無線自組網路中,全向天線的媒介存取機制可能會浪費大量網路容量。為了解決這個問題,研究人員提出使用定向或自適應天線,大幅減少無線干擾,提高無線媒介的利用率和網路吞吐量。

《利用智慧天線增強自組網路性能》討論了這些問題和挑戰。在介紹自組網路後,書中概述了全向天線下的基本媒介存取控制(MAC)和路由協議。接著,書中專注於智慧天線在自組網路中的應用,並回顧了設計用於提高媒介利用率和路由性能的MAC和路由協議的策略,以實現有效的負載平衡。最後,書中分析了基於優先級的服務品質(QoS)路由協議的設計問題,並對比了這些天線與全向天線的潛力。書中最後檢視了自組網路的未解決問題和挑戰。
