Abstract: Data gathering is one of the most important fundamental tasks in wireless sensor network. It consumes large amount of energy of the sensor nodes that reduces network lifetime. So, mobile sinks or mobile collectors are widely used to collect data from the sensor nodes in Wireless Sensor Networks (WSNs). But the main challenge is to discover the optimal path for mobile sink that reduces the energy consumption of the sensor nodes. We propose a Modified Travelling Path Algorithm (MTPA) to find the shortest travelling path for mobile sink that reduces the data latency as well as energy consumption of the sensor nodes. This method provides effective data gathering mechanism for mobile sink. In this approach, the travelling path is the sum of chords of all communication range and line segments between them; after that we will apply B-spline smoothing curve method over it. The effectiveness of proposed method is verified through mathematical proving and in MATLAB simulation. The results show that our proposed approach outperforms existing approaches to network lifetime enhancement and reduces the energy consumption of the sensor nodes.
