Abstract
The ad hoc wireless network that operates in the rich multipath propagation environment is considered. It is supposed that the node-to-node communication link are performed with multi-element antennas and MIMO spatial multiplexing transmitting-receiving strategy in use. The signal-to-interference-plus-noise-ratio (SINR) in the presence of interpath interference is analyzed. The cooperation among transmitted node is used to avoid the stream collision through the concurrent paths when the performance criteria is the quality of service (QoS) of peer-to-peer links is considered. The revised water pouring algorithm (RWPA) that helps to redistribute the power among the transmitted antennas according to QoS performance criteria is discussed. The proposed approach of the stream collision management allows to avoid the interpath interference as well as to maintain at least lower bound of QoS. The simulation part analyzes scenario with two pairs of node-to-node communication links.
