Abstract

In this paper, we propose a powerful but simple algorithm, termed as Schedule Unifying Algorithm (SUA), to minimize energy consumption by border nodes in sensor-MAC (S-MAC) based wireless sensor networks. SUA minimizes energy consumption by unifying the multiple listen and sleep schedules. We use NS-2 to implement and evaluate our algorithm. The experimental results show SUA incorporated S-MAC based nodes consume less energy thereby extends the lifetime 1.7 to 2.5 times more than that of S-MAC based border nodes. Consequently, this prolongs the time period over which two or more virtual clusters can communicate via a border node and therefore extends the lifetime of overall network.
