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： Techniques are provided for determining respective roles of a first meshed node (MN) and a second MN during an authentication process. The first MN and the second MN determine whether at least one of the first MN and the second MN have a secure connection to an authentication server. When the first MN and the second MN each have a secure connection to the authentication server, the first MN and the second MN determine whether a first authentication message forwarding cost (AMFC) associated with the first MN is the same as a second AMFC associated with the second MN. When the first AMFC associated with the first MN is the different than the second AMFC associated with the second MN, the MN having the lower AMFC to an IAP (coupled to the authentication server) assumes the authenticator role, and the other MN having the higher AMFC assumes the supplicant role.
