In wireless sensor network, traditional security mechanisms such as cryptographic methods need a large consumption of resources such as memory, speed, and communication bandwidth. And by using such techniques it is not possible to detect malicious, faulty and selfish nodes that harm to network. Alternatively, trust methods calculate trust of sensor nodes and thereby help to detect malicious, se...

Today, information networks play an important role in supply chain management. Therefore, in this article, clustering-based routing protocols, which are one of the most important ways to reduce energy consumption in wireless sensor networks, are used to optimize the supply chain informational cloud network. Accordingly, first, a clustering protocol is presented using self-organizing map neu...
