Sliding Window Protocol for Internet of Things

Internet of Things (IoT) refers to the concept connecting non-traditional computers and related sources with help internet. This includes incorporating basic computing communication technologies for daily use into Physical things. Security Confidentiality are two major challenges in IoT. In current security mechanisms available IoT, limitations memory, energy resources, CPU IoT devices compromises critical specifications devices. Also, centralized architectures not appropriate because a Single attack point. It is costly defend against attacks targeted on infrastructure. Therefore, it important decentralize architecture meet requirements resource constraints. Blockchain decentralized encryption system large number uses. However, its high computational complexity poor scalability, Traditional environment suitable applications. So, we introduce Sliding window protocol traditional blockchain so that will better suit applications environment. Changing conventional introducing sliding makes previous blocks proof work shape next hash block. SWBC's results analyzed data stream generated from an testbed (Smart Home) real-time. The show proposed improves reduces memory overhead consumes fewer resources Security.
