摘要
Based on the heterogeneous wireless sensor networks, MIMO_SEP scheme is proposed in this paper. When the node runs for cluster-head, the node with different energy would have different probability. At the same time cooperating nodes were designed which form virtual Multiple input multiple output with cluster head to transmit data. MIMO_SEP not only could better handle the heterogeneous energy capacities, but also better use diversity gain. Experimental results illustrate that this algorithm provid longer lifetime and more efficient throughput than the current important schemes.
