摘要：Energy Consumption in Wireless sensor networks is one of the main challenges for researchers. Many researchers have been done for extending the overall network lifetime by minimizing the power consumption of sensor nodes. Most of the work is done over the MAC layer of network in which different kinds of MAC protocol used by sensor networks.. End users typically desire to deploy hundreds to thousands of sensor nodes randomly Producing simple, small, and inexpensive devices also limits the energy resources available for sensor node operation. Replacing or renewing energy resources after deployment becomes infeasible or too costly in most cases, so the protocols and applications must make judicious use of the finite energy resources. As medium access control (MAC) has a significant effect on the energy consumption, energy efficiency is one of the fundamental research themes in the design of MAC protocols for WSNs. In this paper, we described an energy efficiency of IEEE 802.11 protocol which is a standard MAC protocol. The paper presents simulation results of IEEE 802.11 performance on a sensor node with different scenarios. NS-2 is used for simulation purpose.
