Wireless sensor networks are appealing to researchers due to their wide range of application potential in areas such as target detection and tracking, environmental monitoring, and tactical systems. However, lower sensing ranges result in dense networks, which bring the necessity to achieve an effcient medium access protocl 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 using TwoRayGround radio model and AODV protocol considering TDMA and CSMA MAC protocols. We consider consumed energy and delay metrics to evalute the performance of WSN. The simulation results have shown that for CSMA, the consumed energy is better than TDMA. But, the delay of TDMA is better than CSMA.
