Performance Evaluation of Wireless Ad Hoc Networks: From Multicopy Relaying to Multipacket Transmission and Reception,Used
Delivery time: 8-12 business days (International)
In this work, the performance of wireless ad hoc networks is investigated. First, a multicopy relaying scheme for packets in mobile ad hoc networks (MANETs) is proposed, which reduces the delivery delay without changing the throughput order. Also, a method for computing the interference caused from other nodes is presented. Second, the tradeoff among mobility, capacity, and delay for ad hoc networks is studied. By considering nodes that are subject to restrained movements, it is found that mobility is an entity that can be exchanged with capacity and delay. Moreover, the throughputdelay tradeoff is investigated for nodes employing directional antennas and the results are compared with previous work. Third, a new communication scheme based on collaboration among nodes is proposed where the transmission of packets is concurrently possible by employing a manytomany communication framework, i.e., multipacket transmission (MPT) and multipacket reception (MPR). The principles of operation for such technique and two practical examples of implementation using FDMA/CDMA and FDMA/MIMO are presented. Shannon capacity, throughput and delay are computed and compared with related works.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
