METHOD FOR ENHANCEMENT OF MULTICASTING FORWARDING PROTOCOL IN A WIRELESS NETWORK
First Claim
1. A method for enhancing the reliability of a multicasting forwarding protocol in a wireless network, the method comprising:
- establishing a list of multi-point relaying nodes for each of a plurality of nodes in the wireless network, the list of multi-point relaying nodes including neighbor nodes that cover each of the plurality of nodes within two hops;
identifying a first set of nodes in the wireless network that is not already in the list of multi-point relaying nodes, wherein the first set of nodes comprises;
nodes that are the only neighbor node to a node in the list of multi-point relaying nodes;
ornodes that are sequentially previous to a node in the list of multi-point relaying nodes; and
adding the first set of nodes to the list of multi-point relaying nodes.

Abstract
A method for enhancing the reliability of a simplified multicasting forwarding protocol in a wireless network is provided. The method comprises establishing a list of multi-point relaying (MPR) nodes for each of a plurality of nodes. The list of MPR nodes includes neighbor nodes that cover each of the plurality of nodes within two hops. A first set of nodes is identified that is not already in the list of MPR nodes. In a first approach, the first set of nodes includes nodes that are the only neighbor node to a node in the list of MPR nodes. In a second alternative approach, the first set of nodes includes nodes that are sequentially previous to a node in the list of MPR nodes. Once the first set of nodes is identified, the first set of nodes is added to the list of MPR nodes. If the first approach is used, the method further comprises identifying a second set of nodes that is not already in the list of MPR nodes. The second set of nodes comprises nodes that have the largest number of neighboring MPR nodes. The second set of nodes is then added to the list of MPR nodes.
