This paper exploits the idea of cross-layer design for wireless sensor networks to improve the network performance. We present a new energy efficient cooperative routing scheme with space diversity using space-time block codes (STBCs) while improving the link's energy-efficiency. In our solution, the selected multiple nodes act as multiple transmitting and receiving antennas. Full diversity from the...
This work studies the impact of the network resource constraints on the performance of wireless multi-hop relay sensor networks. The cooperative relay method based on the differential space-time block code (DSTBC) in sensor network is introduced. The energy consumption is also investigated for different kinds of relay method. Based on the same total energy consumption requirement, we analyze the system...
