摘要： The present invention provides a system and method for multihop packet forwarding within a multihop wireless communication network. The method uses a data frame format including at least the four address fields to forward packets in a multihop wireless network. The method includes generating a route request packet at a routable device in response to receiving a packet destined for an unknown destination. The route request packet includes an originating device field including an address of an originating device, wherein the originating device generated the packet originally; and a source field, wherein the source field includes an address of the first routable device which generated the route request packet.

摘要： A method for managing secure routing keys (200) for on-demand routing protocols used in a wireless mesh network includes sending an secure routing key from a key distribution node to an access node (201). A temporary communications route which is time and usage limited is initiated (203) between a wireless device and an internet access point when the wireless device initially joins the network. A secure routing key is sent (205) from the internet access point connected with the key distribution center to the wireless device. Thereafter, the secure routing operation can be started to establish secure routes among all wireless devices which have obtained the same secure routing key in the same manner. Thus, the invention defines a simple and efficient key management technique using initial key establishment and re-keying through dynamically updated key vectors.

摘要： A method for tree based spatial TDMA scheduling in a multi-hop wireless network (100). A time slot is requested (101) for non-use by a requesting node to all neighboring nodes. Similarly, the requested time slot is next requested (103) for non-use from the requesting node to its parent nodes. If available, a time slot assignment is then requested (109) from the requesting node to its parent node where the time slot assignment is requested (111) from the parent node to the grandparent node of the requesting node. Finally, all neighboring nodes are then informed (117, 119, 121) if both the grandparent node and parent node grant the time slot request to the requesting node. The invention works to reduce packet collisions by providing link-slot formulation in combination with link direction to compensate for spatial reuse loss in a local optimization setting.
摘要翻译：一种用于多跳无线网络中基于树的空间TDMA调度的方法（100）。请求一个时隙（101）供请求节点不被所有相邻节点使用。类似地，下一个请求的时隙（103）用于从请求节点到其父节点不使用。如果可用，则从请求节点请求（109）从其父节点到请求节点的祖父节点请求时隙分配（111）的请求节点到其父节点（109）。最后，如果祖父节点和父节点都向请求节点授予时隙请求，则通知所有相邻节点（117,119,121）。本发明通过提供与链路方向组合的链路时隙公式来减少分组冲突，以补偿局部优化设置中的空间重用损耗。

摘要： A system and method of security authentication and key management scheme in a multi-hop wireless network is provided herein with a hop-by-hop security model. The scheme adapts the 802.11r key hierarchy into the meshed AP network. In this approach, a top key holder (R0KH) derives and holds the top Pairwise Master Key (PMK—0) for each supplicant wireless device after the authentication process. All authenticator AP take the level one key holder (R1KH) role and receive the next level Pairwise Master Key (PMK—1) from R0KH. The link level data protection key is derived from PMK—1 via the 802.11i 4-way handshaking.

摘要： Unified groupcast data frame formats are provided for improving the efficiency of groupcast communications in multihop wireless mesh networks, and significantly reducing bandwidth consumption. The unified groupcast data frame formats modify existing BSS data frame formats by inserting a mesh end-to-end sequence number into a field that is normally reserved for a sequence control field. In some implementations, a time-to-live (TTL) value can also be inserted into a QoS control field.

摘要： A system and method for supporting multicast in highly dynamic wireless multi-hop networks, such as ad-hoc networks, with good scalability. The system and method provide a multicast routing algorithm to work in wireless ad-hoc networks without any fixed infrastructure nodes present. In doing so, the system and method provide a technique to build a multicast source specific tree on demand, while using a core source node to limit routing overhead. The system and method further provide a repair process to reduce the latency of discovery of topology change, employ a node sequence number mechanism to differentiate between upstream nodes and downstream nodes on the multicast tree in the repair process, and provide an active joining process to reduce the latency of discovery of membership change.
