摘要 无线传感器网络能量受限,策略应尽可能地减少能量消耗,以延长网络寿命。提出一种基于链的能量高效的虚拟MIMO传输策略,对该传输策略进行能耗和时延建模,确定最优的虚拟MIMO链的个数、协作节点个数以及传输速率等网络通信参数。仿真结果表明,即使考虑到电路能耗和信道训练开销,该传输策略也能有效节省能量,提高网络生命期,同时降低时延。 Since wireless sensor networks with limited energy, the transmission scheme must be energy efficient in order to prolong the lifetime of network. In this paper, an energy-efficient chain-based cooperative MIMO transmission scheme is proposed to maximize the network life-time. An optimization model is proposed to find the optimum number of cooperative nodes, transmission rates and number of chains. Simulation results prove that tremendous energy saving is possible with judicious choice of designed protocol parameters even considering the circuit energy cost and channel training overhead, and the scheme can reduce the latency.
