A channel access mechanism in wireless sensor networks

In this paper, A review of wireless data networks will be introduced. I will consider the physical arrangement which is used to interconnect nodes, that is known as the network topology and the process of determining a path between any two nodes over which traffic can pass which is called routing. Next is the switching techniques used in this work, which refers to the transfer method of how data is forwarded from the source to the destination in a network. In addition I will address medium access control protocols for wireless network system. And finally channel assignment strategies and wireless channel models will be reviewed.
