Mobile sink (MS) has drawn significant attention for solving hot spot problem (also known as
energy hole problem) that results from multihop data collection using static sink in wireless
sensor networks (WSNs). MS is regarded as a potential solution towards this problem as it
significantly reduces energy consumption of the sensor nodes and thus enhances network
lifetime. In this paper, we first propose an algorithm for designing efficient trajectory for MS,
based on rendezvous points (RPs). We next propose another algorithm for the same …
