Problems solved by technology

Existing communication protocols such as TEEE-Std 802.11, 1999 Edition (ISO / IEC 8802-11: 1999) standard do not support reliable multicast / broadcast due to their inability to exchange acknowledgment messages (ACK) with multiple recipients.
However, the higher reliability may cause a longer delay or lower overall network throughput as the reliability is achieved by the retransmission of packets in the network.

Embodiment Construction

[0007]In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those of ordinary skill in the art that the invention may be practiced without these specific details. In other instances, well-known methods, procedures, components, units and / or circuits have not been described in detail so as not to obscure the invention.

[0008]Embodiments of the invention may provide a method for dynamic adaptation of a leader node assignment for broadcast and multicast traffic in a wireless network through the use of network characterization and traffic type. According to embodiments of the invention, the method may include assigning each multicast stream an independent leader based on the characteristics of the traffic stream and the distribution requirement for the particular type of traffic.

[0009]Embodiments of the invention may be used in a variety of applications. Some embodimen...

Abstract

Method and apparatus for reliable multicast communication over wireless network are provided. According to embodiments of the invention, the method includes determining a priority category for a multicast communication to be transmitted. The method includes designating, for the multicast communication, one of the multicast communication recipients as a leader based on the priority category and multicast diagnostics information received from the multicast communication recipients. The leader is assigned to transmit to the multicast communication source an acknowledgment frame indicating receipt of a multicast communication frame received from the source.

Description

BACKGROUND OF THE INVENTION[0001]Reliable multicast and broadcast of wireless communications are gaining importance with the development in technology. In organizations this may be exemplified by the fact multicast and broadcast are becoming a required capability for delivery of live conference, web training, and wireless network management. In home networking, broadcast video streaming can be used for home entertainment and gaming. In hospital environments, broadcast can be used for commercial advertisement and television broadcasting.[0002]Existing communication protocols such as TEEE-Std 802.11, 1999 Edition (ISO / IEC 8802-11: 1999) standard do not support reliable multicast / broadcast due to their inability to exchange acknowledgment messages (ACK) with multiple recipients. Obtaining a level of reliability in a multicast communication may be achieved by designating for a given wireless network, a leader station to respond to the multicast traffic with an ACK, thereby notifying the...
