In this work, the performance of wireless ad hoc networks is investigated. First, a multi-copy 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 trade-off 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 throughput-delay…mehr

In this work, the performance of wireless ad hoc networks is investigated. First, a multi-copy 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 trade-off 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 throughput-delay trade-off 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 many-to-many communication framework, i.e., multi-packet transmission (MPT) and multi-packet 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.
