The Throughput for Multi-hop Relay Wireless Sensor Networks Based on Cooperative Diversity

This paper studied the problem of the throughput of multi-hop multi-relay wireless sensor networks based on the cooperative diversity technology. At first, the paper established the cooperative diversity model for multi-source, multi-sink and multi-relay sensor networks, on which the specific expression of throughput of wireless sensor networks was deduced, it not only prove that the throughput performance of multi-hop multi-relay wireless sensor networks would be increased by the cooperative diversity technology, but also gave the criterion for discussing further the application effect of the technical scheme such as the cooperative selection strategy and so on in actual multi-hop multi-relay wireless sensor networks. In the other hand, the paper theoretically proved that cooperative diversity could improve the throughput of multihop multi-relay wireless sensor networks.
