Abstract : A Multiple-Input Multiple-Output (MIMO) transceiver provides extremely high spectral efficiencies by simultaneously transmitting multiple data streams in the same channel. Some research works have used MIMO technology to increase data rate or reduce energy consumption at communication links in wireless sensor networks. Since all layers of the protocol stack affect network performance, an efficient system should exploit the advantage of MIMO technology across all layers as well as the underlying hardware where the resource constraints actually come from. In this paper, we show a joint design of MIMO aware network architecture, routing and MAC protocols underlying physical hardware. Our network architecture is reconfigurable with two functions: node-joining and node-leaving. We show that our design can fully exploit the advantage of MIMO technology and multiple-optimize network throughput, network lifetime and network reconfiguration cost in a dynamic sensor network.
