D2HCP PROTOCOL IN AD HOC NETWORKS: MERGING OF SUB-NETWORKS AND ADDRESS CONFLICT RESOLUTION
First Claim
1. A method for detecting a merging situation of two ad-hoc sub-networks implementing a D2HCP addressing protocol, the first sub-network comprising a plurality of nodes and the second sub-network comprising a plurality of nodes, each node of each sub-network comprising a data set comprisingan identifier of said node;
- identifiers of the known nodes of an authentication data set of said node;
an IP address associated with the identifier of each node referenced in the authentication data set;
at least one identifier of the sub-network to which said node belongs,the method comprising;
discovering a second node of the second sub-network by a first node of the first sub-network, by receiving by the first node a so called discovery data frame, transmitted by the second node for determining a situation requiring merging of both sub-networks;
exchanging setup data between the first node and the second node, comprising;
the identifiers of each node;
a size of each sub-network;
the identifier of each sub-network (ID20, ID21);
comparing the sizes of each sub-network enabling a master node and a slave node to be defined from the first and the second nodes, the slave node retrieving a set of identifiers of the nodes of the sub-network of the master node as well as the IP addresses associated with each of said identifiers, the determination of the slave node and the master node enabling the merging of both sub-networks in a single network to be setup.

Abstract
A method for merging two sub-networks of an ad hoc network implementing the D2HCP routing protocol includes transmitting a first data set from the master node to the slave node, the first set including the identifiers of all the nodes of the sub-network containing the master node, the IP addresses of all the nodes of the sub-network containing the master node, each node identifier being associated with a single IP address, comparing each received IP address of the first set with the IP addresses of the routing table of the slave node in order to identify a list of duplicates corresponding to nodes of each sub-network having the same IP addresses.

14. A method for merging two sub-networks of an ad-hoc network implementing a D2HCP routing protocol, a master node being determined from a first sub-network and a slave node being determined from the second sub-network, the method comprising:
-
emitting a first data set from the master node to the slave node, said first set comprising; the identifiers of all the nodes of the sub-network comprising the master node; the IP addresses of all the nodes of the sub-network comprising the master node, each identifier of the node being associated with a single IP address, comparing each received IP address of the first set with the IP addresses of a second authentication data set of the slave node, the latter set comprising the identifiers and the IP addresses of the nodes known to the slave node of the second sub-network, so as to identify a list of duplicate nodes corresponding to nodes of the second sub-network having the same IP addresses as nodes of the first sub-network. - View Dependent Claims (15, 16, 17, 18, 19)
