Underwater wireless sensor network (UWSN) provides a promising solution for discovering the aqueous environment efficiently which operates under many important constraints. At one side, these environments are not sufficient in case of energy efficiency and reliability. So in our paper we propose to develop a reliable and energy efficient cluster-based architecture for UWSN. Here the nodes cluster themselves and forms a cluster head. Next by deploying the courier nodes in the network data is aggregated from the CH. They also enable an intercluster communication to forward the sensed data. This increases the lifetime and the delay is less with the reduced buffer overflow problem.
A unit based scheduling technique is proposed to assess networks of the given project and find out the optimum schedule. The proposed approach uses an iterative method to execute unit expediting and the expedition is done to the desired amount for all activities along the critical path. The output of the proposed approach includes a distribution of the total cost of project, duration of project completion and it is mainly applicable where cost and duration are of major issues. A computer program has also been developed using the C programming language to support the efficiency of the logic applied in the algorithm. A civil construction scheduling has been solved illustrating the validity of the proposed algorithm. This algorithm can serve as an important tool for the project managers to run the projects speedily and successfully.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
