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 links are performed with multi-element antennae 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 nodes 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. The revised water pouring algorithm (RWPA) that helps to redistribute the power among the transmitted antennae according to QoS performance criteria is discussed. The simulation part analyzes scenario with two pairs of node to node communication links.
