Wireless Access Protocol Design,s into a single, cooperative, and statistical multiplexing global queue. Additional loss of resources is the cost for organizing separate demands. In wireless access protocol design, this cost will involve some combination of idle resources, collisions, and control overhead..Metrics defined in terms

Multiple Access Communications,amount of coordination needed to control potentially conflicting packet transmissions. At one extreme is random access where no coordination is provided and packet collisions are possible. At the other end of the spectrum, the class of fixed assignment access protocols eliminates collisions entirely

Fixed Allocation Access Protocols,ransmitting or not. Thus, more users can share a given channel bandwidth in such schemes provided all users are willing to tolerate greater delay. A key characteristic of polling protocols is the reliability in providing channel access. Such protocols are attractive for short-range wireless networks

Contention Protocols,iple access techniques attempt to address this weakness. In the tree algorithm, users involved in a collision are broken down into smaller groups. This process continues until there is only one ready user in the group. The URN protocol restricts the number of users accessing the channel according to

Spread Spectrum Multiple Access,f success of a packet in the presence of other signals is very difficult to evaluate. Several methods that have the potential of raising the capacity of spread spectrum systems significantly include multiuser detection, interference cancellation, and interference suppression.

These broadband networks aim to provide integrated, packet-oriented, transmission of text, graphics, voice, image, video, and computer data between individuals as well as in the broadcast mode. Although the underlying access protocols supporting these networks have evo
