Wireless sensor networks (WSN), is a novel technology which integrates the technologies of sensor, embedded computing, distributed information transaction and wireless communication. It is made up of lots of sensor nodes of which the character is self-organizing, mini-size, low cost and flexibility .Different kinds of nodes utilized in this network can cooperate to monitor 12hot cheap prom dresses sense and gather information of area they monitored. The data they gathered will be forwarded though multi-hop to the terminals and to be deeply dealt with. Wireless sensor networks chi flat iron store implement the effective connectivity of the physical world, the computer world and human society, the characteristics of self-organizing; mini-size, low cost and flexibility give it a very broad sell discount wedding dresses perspective in many fields such as military, environment science, medical treatment, space exploration and business etc.In this paper, through analysis of the wireless sensor network protocol stack, an discount wedding dresses improved program is given, including the following two plus size wedding dresses aspects:(1)A MAC protocol called ATMAC in which the duty cycle of nodes can be adjusted in accordance with traffic. In wireless sensor networks, based on famous TMAC protocol, low power energy consumption, low latency for target, ATMAC mainly adopts three options. First, adaptive and multi-level duty cycle is considered. The second is adaptive contention window. The third, Priority queue. All of these options can be utilized to save energy, minimize latency, increase output etc.
