2、 population accelerated sharply and the medical costs continue to vicious inflation. The body becomes part of the communication network because of the emergence of the Wireless Body Area Networks can effectively monitor

3、the human body health. It is regarded as one of the key support technology that can solve the sharply accelerated aging population and medical expense hyperinflation. Wireless Body Area Network（WBAN）is also a kind of wir

4、eless sensor network， generally using batteries to supply power. But the energy resources are finite. The movement of the body can also bring the change of the channel quality. So energy is one key factor that restricts

5、the development of WBAN. It is especially important to reduce the network energy consumption and prolong the life of the network by designing effective communication protocol. In WBAN, the RF part of the sensor consumes

6、most of the energy. The MAC protocol plays a significant role in controlling/duty cycling of RF module and reducing the average energy consumption of the sensor node. This thesis expounded the most important attribute of

7、 a good MAC protocol are energy efficiency and Quality of Service. The different kinds of MAC protocol were illustrated and compared.and a conclusion about the proposed WBAN MAC protocols was also made . Network topology

8、 is a reaction of the relationship between each element in the network. It is the first step to construct wireless body area network and the basis for the implementation of communication protocol. It has a significant im

9、pact on the network performance, reliability, communication expenses, etc. Routing protocol is mainly used to send packets from the source node to the destination node in the network. During this process, routing protoco

10、l can find the optimal path between source node and destination node, and then transfer packets on the optimal path. In WBAN, the number of sensor nodes is bigger and its energy is finite. At the same time, due to the pa
