Now-a-days efficient data gathering scheme in wireless sensor networks is has got more attention towards the research and development. This issue is taken care by using adopting mobility and Space Division Multiple Access (SDMA) techniques. Mobile collectors are work like mobile base stations which collect the data from different sensors related to it. This joint technique has been implemented by deploying single and multiple mobile collectors (SenCar) which helps to minimize the total data gathering time i.e. the moving time and data uploading time of SenCars.
