Sink Scheduling, in the form of scheduling multiple sinks among sink sites to leverage traffic burden, is an effective mechanism for the energy-efficiency of wireless sensor networks (WSNs). Due to the inherent difficulty (NP-hard in general), existing works on this topic mainly focus on heuristic/greedy algorithms and theoretic results remain unknown. In this paper, we fill in the research blank...
Owing to the complexity of the production environment the rescheduling has become the core problem in the workshop management. This paper analyzed the dynamic disturbances in the production environment, build a mathematic model and then present a workshop rescheduling algorithm based on the Rescheduling List, which could gather to-be-rescheduled procedures to shorten the searching space. The algorithm...
Recently, sink deployment, in the form of deploying the sink among different sites so as to leverage traffic burden, is shown to be a promising scheme to save energy and prolong network lifetime in wireless sensor networks. For this paradigm, the choice of sink sites plays a critical role in the overall system performance. In this paper, we address the optimal deployment problem for the sink in wireless...
