Aggregated PSO for Secure Data Transmission in WSN Using Fog Server

Privacy of data in Internet Things (IoT) over fog networks is the biggest challenge security Wireless communication networks. In Sensor Network (WSN), current research on computing with IoT gaining popularity among devices network. Moreover, aggregation will reduce energy consumption WSN. Due to open and hostile nature WSN, secure major issue. The existing methods its associated approaches are lack limited functions, heavyweight, issues related performance overhead. Besides, overload node result high latency, scalability, storage, degraded reliability order overcome these issues, this proposed work has used two schemes for transmission network transmission. secret transferred between Fog server transmitted through aggregator node. If placed far away from node, it may send neighbor aggregator. And append message receiving method. addition that, can extract extractor cost energy, Clustered Particle Swarm Optimization (CPSO) method form clusters. This avoid unnecessary during ensures secured so that base station know origin sender validity received message. Therefore, computation authorization requires1MC+1H requires (n+2) MC+1H which lesser than methods.
