The existence of a mobile sink for gathering data significantly extends WSN's lifetime. In recent years, a variety of efficient rendezvous points-based sink mobility approaches has been proposed for eliminating the “bottleneck” problem nearby the sink and diminishing sensors traffic load. However, the frequent detection of rendezvous points best collection to establish the mobile sink’s optimal path is high energy consumption and buffer overflow process in large-scale homogenous WSN and an effective but quite complicated process in heterogeneous WSN. The controllable-based approaches in sink mobility approached were targeted in many research specifically for the elimination of the energy hole problem. However, further developments can be demonstrated and achieved in this type of mobility management system. In this paper, a well-rounded strategy involving an energy-efficient routing protocol along with a controllable-based sink mobility method is proposed to extirpate the “bottleneck” problem. This paper fused the (fuzzy-A*) routing protocol for mitigating the energy consumption in data forwarding along with a novel sink mobility method based on grid partitioning and fuzzy inference system that takes account of the average residual energy, sensors density, average traffic load, and sources angles to find out the optimal new location for the mobile sink. The proposed method showed a great result when it was compared with (fuzzy-A*) protocol in the case of a static sink by diverse metrics.
