A MAC Protocol for Provisioning QoS and Energy-Efficiency in WSNs

Zahra Zarei, S. Mostafa Safavi, and Akbar Abbasi
Abstract—Reliable environment monitoring and information collection with an energy efficiency mechanism is a goal in new wireless sensor network applications. In some applications, reliability and delay are two important and vital parameters. Lifetime improvement in wireless sensor networks is also a challenging issue. Therefore, in this paper, a new protocol is proposed for solving these problems. The proposed protocol uses CSMA/CA basic algorithm and some simple mechanisms to improve energy-efficiency and network reliability with reasonable end-to-end delay. In this paper the simulation results of the proposed protocol are compared with both S-MAC and 802.11 protocols in the same condition that show better performance.

Index Terms—Energy efficiency, MAC protocols, quality of service (QoS) provisioning, reliability, wireless sensor network.
