The Wireless Sensor Networks (WSNs) have a wide range of applications such as target detection and tracking, environmental monitoring, and tactical systems. However, lower sensing ranges result in dense networks, which brings the necessity to achieve an efficient medium access protocol subject to power constraints. Various MAC protocols with different objectives were proposed for wireless sensor networks. In this paper, we evaluate the performance of WSNs considering TwoRayGround radio model, AODV and DSR routing protocols, and TDMA and CSMA MAC protocols. We consider depletion and Routing Efficiency (RE) to evaluate the performance of WSNs. The simulation results show that the depletion of CSMA is better than TDMA for AODV protocol. However, the depletion of TDMA is better than CSMA for DSR protocol. The RE of CSMA is higher than TDMA for AODV protocol. While, the RE of TDMA is higher than CSMA for DSR protocol.
