Channel Access Mechanism in Application-Oriented Short Distance Wireless Communication System
Guo Ai-huang · Modern Electronics Technique · 2006
Short distance wireless communication in the selforganizing pattern has the advantages such as simple equipment,convenient application,low cost,etc,so it has become the hotspot in the research and application fields.And its channel access is one of the key technologies.In this paper,to resolve the problem of channel access in the application of short distance wireless communication system,two mechanisms are discussed which are roll-call access and contention access.The two mechanisms are compared from the principles,performances,advantages and disadvantage.Then their applications are analyzed with the system cost,complexity,performance as the parameters.The analysis indicates that the two channel access mechanisms have different characters,and suit for different applications.In conclusion,they are practical wireless access modes in the self-organizing pattern.
