In this paper, the authors investigate leach protocol by varying size of data packet & position of base station (sink) to prolong the network lifetime. The size of data packet taken are 1000, 2000, 3000, 4000 bytes. For the case 1000, simulation results show that nodes still alive for 17000th rounds. The Position of BS (Base Station) is set (50, 50), (50, 75), (50, 100), (50, 150). For this case (50, 50) simulation results show that nodes still alive for 4500th rounds. In general, nodes survived for longer time period provided smaller size of data packet & the position of BS in middle of network area.
