Multiple rendezvous protocols and architectures for wireless ad hoc networks

Escalation in mobile devices has powered the demand for wireless networks. With the ripening of industry standards and the deployment of wireless networking across a broad commercial section, wireless technology has expanded over the age. Wireless ad-hoc network technologies and standards such as IEEE 802.11s (WANET) are efficient, economic, simple to send, permit the brisk setup of a remote system among a gathering of portable stations, where the stations correspond with one another without the support of a base. To increase the performance of ad hoc wireless networks multiple rendezvous multi-channel MAC protocols are used. But this multi-channel MAC protocols has certain disadvantages such as busy receiver problem, multi-channel hidden terminal problem etc. In this paper we are outlining some of the multiple rendezvous protocols and their properties. Also provide a comparison between them, for studying various problem phased by different multiple rendezvous protocols. By using a proper broadcasting mechanism we can solve many of these problems. For this we are mentioning a special interface for broadcasting and broadcast a packet according to the node behaviour.
