摘要:

针对无线传感器网络高能效传输要求,提出了一种基于虚拟多输入多输出(MIMO)传输的协作
中继节点选择算法. 该算法不考虑源节点到目的节点1次传输中1跳或多跳能量消耗最小化问
题,而是减少整个网络执行整个应用的能量消耗. 仿真结果表明,与直接及最小化能耗传输
相比,本文算法延长了网络的生命周期.

Abstract:

A partners choice algorithm is proposed based on cooperative multi-input multi-output (MIMO) transmission in energy-constrained sensor networks. Compared with existing work, the distributions are that the cooperative nodes choice in every transmission is not based on minimizing energy consumption but balances residual energy between participant nodes including source node. The efficiency of the proposed algorithm by simulation is validated when comparing with the direct transmission and minimizing energy consumption transmission.
