Developing an intelligent transportation system has attracted a lot of attention in the recent past. Moreover, with growing number vehicles on road most nations are adopting transport (ITS) for handling issues like traffic flow density, queue length, average speed traffic, and total passing through point specific time interval so on. ITS by capturing images videos cameras, helps control centres monitoring managing traffic. Efficient unfailing vehicle detection is crucial step ITS. This study...

Wireless sensor network (WSN) consists of spatially distributed miniature size and autonomous nodes along with batteries as a power source. The major bottleneck WSN is efficient energy utilization. consumption for transmission signals increases the distance. This problem addressed in this study. study presents strategy, namely distance‐based dynamic duty‐cycle allocation (DBDDCA) algorithm. In DBDDCA, longer distance from cluster head (CH) transmit relatively less time order to save energy....

Energy minimization is one of the paramount issues in designing wireless sensor network and becomes more complex for multi-hop transmission. Furthermore, selection multi hop route packets transmission also a tedious task.
