MAXIMIZING NETWORK CAPACITY AND RELIABLE TRANSMISSION IN MIMO COOPERATIVE NETWORKS

K.Swathi

Abstract: Network capacity is an important factor to measure the performance of a network. Cooperative networking is a phenomenon which helps network to have significant gains in terms of transmission reliability and network capacity. Cooperating networking has been applied to multi-hop ad hoc networks. However, the existing works have two limitations. They support only single antenna model and three node relay scheme. The reason behind this limitation due to lack of complete understands of optimal power allocation structure Multiple Input and Multiple Output (MIMO) cooperative networks. Recently Liu et al. studied structural properties with respect to MIMO cooperative networks in presence of node power constraints. Each power allocation at source follows corresponding MIMO structure so as to ensure optimal power allocation. They establish relationship between cooperative relay and pure relay to quantify performance gain. In this paper we did experiments on this concept. Our simulations reveal that the proposed system for cooperative network is able to achieve both transmission reliability and network capacity.
