摘要： A method is provided for mobile wireless ad hoc network, where network nodes using the same routing protocol are uniformly sharing a single contention channel. Network nodes are able to dynamically and distributedly switch roles according to surrounding network environment so that routing functions can be either activated or de-activated in order to improve routing efficiency and increase network capacity by reducing unnecessary routing overhead (which is caused by excessive redundant routing nodes). In addition, the nodes are able to self organize themselves into hierarchies or different roles according to different routing strategies. The proposed role-switching method can be implemented on network nodes which support existing routing protocols or native routing protocol proposed herein to further exploit the proposed role-switching method.

摘要： An automated and distributed method is provided for configuring addressing of nodes in a wireless network, where the nodes includes at least one wireless interface and a network interface which connects to an external network. Briefly, the method includes: assigning a wireless network address to the wireless interface associated with the node; assigning another external network address to the external network interface associated with the node in a manner where a subnet identifier of the network address for the external interface correlates to a host identifier of the network address for the wireless network. The method may further include assigning further network addresses to one or more network devices which share the same subnetwork as the external network interface of the node.

摘要： A method is provided for selecting a route for transmitting data packets amongst nodes in an ad hoc network. The method includes determining a metric which is indicative of link stability between the nodes in the network; initiating a route discovery procedure that generates a plurality of candidate transmission paths between a source node and a destination node; and selecting a transmission path from amongst the plurality of candidate paths using the metric for nodes associated with each candidate path. The metric may be further defined as link duration (i.e., an amount of time the node maintains a link with neighboring nodes link duration).

摘要： A multicasting network route provisioning system for use in allowing an in-session multicast application to switch its path on need includes a datastore of multicast addresses operable to route multicasting traffic over different network paths. It also includes a datastore of multicasting sessions having flows of various flow patterns, wherein a flow pattern is defined in terms of a set of source and destination network nodes, and corresponds to multiple routing network paths. Further, a session management module is adapted to aggregate multicasting session flows by allocating multicast addresses to multicasting sessions based on correspondence between the network paths and flow patterns of the multicasting sessions, thereby ensuring that flow patterns corresponding to different sets of network paths do not share a same multicast address.
