Considering the computation resources available with sensor devices and the value and validity of Cognitive Wireless Communication Network (CWCN), traditional blockchain is not feasible for CWCN. Further, considering the security and privacy for CWCN that can directly impact human life (as in the case of ambient assisted living applications), blockchain provides a good solution for such applications, however, with some simplicity in the computation of Proof of Work (PoW). Therefore, the fourth objective solution comes up with a simplified energy-efficient blockchain implementation for CWCN that consumes less energy in computation time. The energy-hungry blockchain has been implemented on resource-constrained CWCN for ambient assisted living applications specialized for elderly care. The process includes a collection of physical environmental parameters on a single board computer-based CWCN. The implementation includes possible simplification in the most energy-consuming process, i.e., the mining process, which makes it energy efficient in computation time as energy consumption is a computation time factor.

认知无线通信网络 (CWCN) 的节能区块链实施

考虑到传感器设备可用的计算资源以及认知无线通信网络（CWCN）的价值和有效性，传统的区块链对于CWCN来说是不可行的。此外，考虑到 CWCN 的安全性和隐私性会直接影响人类生活（如环境辅助生活应用程序），区块链为此类应用程序提供了很好的解决方案，但是工作量证明（PoW）的计算有些简单）。因此，第四个目标解决方案为 CWCN 提出了一种简化的节能区块链实现，在计算时间内消耗更少的能量。耗能区块链已在资源有限的 CWCN 上实施，用于专门针对老年人护理的环境辅助生活应用。该过程包括在基于单板计算机的 CWCN 上收集物理环境参数。该实现包括对最耗能过程（即挖掘过程）的可能简化，这使得计算时间更加节能，因为能耗是计算时间因素。
