Simulation and analysis of energy consumption for S-MAC and T-MAC protocols on wireless sensor network

The need for the energy consumption of wireless sensor networks (WSN) is a major and fundamental issue. Each node in a wireless sensor network is only supplied by a battery that it has a limited energy reserve. Each node in a wireless sensor network is also scatteredly laid on the sensor field that the contention-based MAC protocol scheme in WSN should be able to establish a communication link to transfer data. This research focused on analyzing the amount of energy consumption required for S-MAC protocol and T-MAC protocol. It continued with 802.11 MAC protocol. The simulation results show that the contention-based MAC protocol which can save energy or use low energy consumption is T-MAC protocol. Its ability to save energy is at least 25% better than that of S-MAC protocol. Its ability can be even better when compared with the 802.11 MAC protocol. If we use duty cycle as a variable which affects the energy consumption, the T-MAC protocol can save energy consumption 10% more than the S-MAC protocol can.
