In this thesis, we investigate the performance of wireless ad hoc networks. First, we propose a multi-copy relaying scheme for packets in mobile ad hoc networks MANETs, which reduces the delivery delay without changing the throughput order. We also present a method for computing the interference caused from other nodes. Second, we study the trade-off among mobility, capacity, and delay for wireless ad hoc networks. By considering nodes that are subject to restrained movements, we found that mobility is an entity that can be exchanged with capacity and delay. Furthermore, the throughput-delay trade-off is investigated for nodes employing directional antennas and the results are compared with previous work. Third, we propose a new communication scheme based on collaboration among nodes where the transmission exchange of packets is concurrently possible by employing a many-to-many communication framework. We present the principles of operation for such a technique, followed by two practical examples of implementation using FDMACDMA, and FDMAMIMO systems. Shannon capacity, throughput and delay are computed and compared with related works.
