Towards sustainable energy efficient routing for dynamic ad-hoc communications in smart cities
The minimal energy-efficiency in ad-hoc environment usually selects path with minimal energy path cost in multi hop communications. Choosing a path with minimal energy path cost does not guarantee in link stability and reliability of individual nodes in the network. A novel energy-efficient routing protocol named as Link Error Recovery Max-Min Path (LER-MMP) has been proposed. This protocol includes total energy spent on reliable transmission forl optimized paths in dynamic network. The link error rate that affects re-transmission with increased transmission error rate and therefore LER-MMP protocol selects an efficient path that has less number of long-distance hops for reliable network connectivity. The simulation result proves that LER-MMP can adapt reliable re-transmission with less link error rate and outperforms than existing protocols. The statistical result shows that LER-MMP protocol is efficient during link disconnections for concurrent communications in dynamic smart city environment.
