Rising energy costs, losses in the present-day electricity grid, risks from nuclear power generation, and global environmental changes are motivating a transformation of conventional ways generating electricity. Globally, there is desire to rely more on renewable resources (RERs) for generation. RERs reduce greenhouse gas emissions may have economic benefits, e.g., through applying demand side management with dynamic pricing so as shift loads fossil fuel-based generators RERs. The grid...

To keep the services and applications of intelligent transportation system stable active, vehicular ad hoc networks (VANETs) are considered as an essential building block to maintain manage its features. A wide deployment VANETs is possible only after addressing numerous research challenges. One most complicated issues consists designing a routing strategy, taking into consideration several serious constraints, especially in network such VANET. The severity these would be increased...

Data transportation and routing in Internet of Things (IoT) is a challenging issue where massive data collection gathering are predictable.
