Polymorphic broadcast and multicast services for wireless networks
First Claim
1. A method of communicating in a wireless adhoc communications network, the network including a plurality of nodes configured for wireless communication therebetween, the method comprising:
- receiving, at a receiving node, a message originating from a source node, the receiving and source nodes being included in the plurality of nodes in the network;
determining whether the receiving node is of a node type intended to process the message;
determining whether the receiving node is less than a predetermined distance from the source node;
the receiving node processing the message when the receiving node is of the node type intended to process the message and when the receiving node is less than a predetermined distance from the source node;
wherein the message includes a position of the source node and a predetermined distance information, and further wherein determining whether the receiving node is less than a predetermined distance from the source node includesdetermining a position of the receiving node,comparing the position of the source node with the position of the receiving node to compute a distance between the source node and the receiving node, anddetermining whether the distance between the source node and the receiving node is less than the redetermined distance information.

Abstract
A method of communicating in a wireless ad-hoc communications network is disclosed. The network includes a plurality of nodes configured for wireless communication therebetween. According to the method, a receiving node receives a message originating from a source node. The receiving and source nodes are included in the network. It is determined whether the receiving node is of a node type intended to process the message. It is determined whether the receiving node is less than a predetermined distance from the source node. The message is processed by the receiving node when the receiving node is of the node type intended to process the message and when the receiving node is less than a predetermined distance from the source node.

9. A method of communicating in a wireless ad-hoc communications network, the network including a plurality of nodes configured for wireless communication therebetween, the method comprising:
-
receiving, at a receiving node, a message originating from a source node, the receiving and source nodes being included in the plurality of nodes in the network; determining whether the receiving node is of a first node type intended to process the message; determining whether the receiving node is less than a first predetermined distance from the source node, the first predetermined distance being associated with transmissions to nodes of the first node type; determining whether the receiving node is of a second node type intended to process the message; determining whether the receiving node is less than a second predetermined distance from the source node, the second predetermined distance being associated with transmissions to nodes of the second node type; the receiving node processing the message when at least one of the receiving node is of the first node type and the receiving node is less than the first predetermined distance from the source node, and the receiving node is of the second node type and the receiving node is less than the second predetermined distance from the source node is true. - View Dependent Claims (10, 11, 12, 13, 14)

15. A wireless ad-hoc network, comprising:
-
a plurality of communications devices communicating with each other, each of the devices being of one of a plurality of device types; wherein a message from one of the devices contains an instruction to process the message only by devices of a predetermined device type that are within a predetermined distance from said one of the devices; wherein the message further contains a position of said one of the devices and information relating to the predetermined distance, and further wherein the position of said one of the devices is compared with a position of a device receiving the message to determine a distance therebetween, and wherein said distance is compared with the information relating to the predetermined distance to determine whether the device receiving the message is within the predetermined distance. - View Dependent Claims (16, 17, 18)
