Trust evaluation plays an important role in securing wireless sensor networks (WSNs), which is one of the most popular network technologies for Internet Things (IoT). The efficiency trust process largely governed by derivation, as it dominates overhead process, and performance WSNs particularly sensitive to due limited bandwidth power. This paper proposes energy-aware derivation scheme using game theoretic approach, manages while maintaining adequate security WSNs. A risk strategy model...

Security is one of the most important issues we should solve before deploying wireless sensor networks in practical applications. Compared with traditional networks, industrial environment harsher and more complex, which has a higher requirement for network security. Although cryptographic primitives can provide capability to resist against attacks from external network, they not address problem caused by internal failed or compromised field devices. In this paper, propose trust management...

Security in mobile wireless sensor networks is challenging to achieve, as have many different characteristics from wired such lack of center infrastructure, vulnerable links and rapid changes topologies, etc. However, earlier studies on security issues mainly aim at utilizing cryptography authentication, which are not only constrained by hardware resources, but also available for the attacks interior networks. Trust management schemes primary supplementary means encryption. In this paper, we...
