| The advancement in micro-technology development made it possible to design very small, low cost, and low power device like a Wireless Sensor Networks (WSN) node. These networks are able to sense, process, and transmit information. These capabilities are useful for some monitoring applications like weather, military, health. One of the major constraints for WSN is the lifetime, for them to be useful they should operate for long time without the need to replace or recharge their power sources. Therefore, we proposed a method to maximize the lifetime of these networks by minimizing the amount of energy each node consumes. This method is easier to use and implement and requires less computational power compared to the solutions that are based on linear program. Also a special method is proposed for sensor networks that are distributed in a uniform topology where distances are equal between nodes. |
