A Low Energy Consuming MAC Protocol for Wireless Sensor Networks

Abstract

In a Wireless Sensor Network (WSN), sensor nodes are small autonomous devices that run on batteries. When the battery of a sensor node dies, it stops functioning. Generally, a sensor node loses more energy in communication than in sensing or processing activities. The proposed model, Low Energy Consuming Medium Access Control (LECMAC), minimizes energy consumption by reducing the number of communications in the network. Hence, the WSN lifetime increases. Two existing models, ES-MAC and LEACH, are compared to LECMAC in four various layouts. The experimental results show that LECMAC outperforms ES-MAC and LEACH in extending network lifetime.
