Performance Analysis of C-V2I-based Automotive Collision Avoidance
One of the key applications envisioned for C-V2I (Cellular Vehicle-to-Infrastructure) networks pertains to safety on the road. Thanks to the exchange of Cooperative Awareness Messages (CAMs), vehicles and other road users (e.g., pedestrians) can advertise their position, heading and speed and sophisticated algorithms can detect potentially dangerous situations leading to a crash. In this paper,...
متن کاملPerformance of Directional Collision Avoidance in Multihop Wireless Networks
This chapter analyzes the performance of directional collision avoidance schemes, in which antenna systems are used to direct the transmission and reception of control and data packets in channel access protocols based on four-way handshakes to try to avoid collisions. The first analytical model to consider directional reception and the possible difference in gain between omni-directional and d...
متن کاملPerformance evaluation of collision avoidance schemes in ad hoc networks
IEEE 802.11 DCF (Distributed Coordination Function) is a popular protocol used for the physical and MAC layers in most ad hoc networks. DCF employs carrier sense multiple access with collision avoidance (CSMA/CA) and a binary slotted exponential backoff. It has been observed that the hidden and exposed terminal problems among stations are responsible for DCF’s performance-degradation. The issue...
متن کاملPerformance of Directional Collision Avoidance in Ad Hoc Networks
This paper analyzes the performance of directional collision avoidance schemes, in which antenna systems are used to direct the transmission and reception of control and data packets in channel access protocols based on fourway collision avoidance handshake. We present an analytical model that considers both directional reception and the possible difference in gain between omnidirectional and d...
متن کاملanalysis of power in the network society
اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
