Recent development in sensor technologies encourages the adoption of mobile data collectors (MDCs), that is, vehicles or robots, to collect data in the Internet of Things (IoT) environment. However, the slow travel speed of the MDCs leads to significant delays in the transmission of data. This work proposes an optimal region location point based route planning (ORLP‐RP) scheme to construct a shorter tour with minimized data delivery latency. Primary goal of the work is to distinguish the overlapped wireless sensor network (WSN) clusters and specify the overlapped regions to find optimal location points within each identified region to ensure one‐hop data gathering from each cluster. Thereafter, MDC trajectory is formed by using the nearest‐neighbor (NN) heuristic approach that generates a near optimal solution. In performance evaluation, the ORLP‐RP scheme has been compared with the existing algorithms …
