Pollution data needs to be collected in urban areas for monitoring purposes. Among various approaches moving sink/ data mule based approach is more effective from energy consumption perspective. In this approach mobile sink gathers information from the static sensors of the network and transfer it to uploading server or base station. The Sink Trail protocol is one such protocol which handles this task in an efficient way. The logical coordinate system of Sink Trail protocol ease routing and forwarding without using GPS.The impact of different moving patterns of sink can affect the performance of packet received and energy consumption. In this paper various sink movements such as straight line, linear and zigzag pattern at constant speed is considered for protocol evaluation. The size of the network is also varied for different movements. The simulation results demonstrate substantial differences for different sink movements.
