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： 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的基于树的空间TDMA调度的方法（100）。请求（101）时隙以供请求节点不用于所有相邻节点。类似地，接下来从请求节点向其父节点请求（103）未请求的请求时隙。如果可用，则从请求节点向其父节点请求（109）时隙分配，其中从父节点向请求节点的祖父节点请求（111）时隙分配。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）。本发明通过结合链路方向提供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 method for transmitting groupcast data in a wireless mesh communication network as provided improves security of groupcast data. The method comprises processing, at a supplicant node, authentication handshake data received from an authenticator node, wherein the supplicant node is a next-hop neighbor of the authenticator node away from a root node. The supplicant node then stores a group transient key (GTK) received from the authenticator node. Next, the supplicant node processes authentication handshake data received from a third node, wherein the third node is a next-hop neighbor of the supplicant node away from the root node. The GTK is then transmitted from the supplicant node to the third node. Encrypted groupcast data are then generated at the supplicant node by using the GTK to encrypt groupcast data received from the authenticator node. Finally, the encrypted groupcast data are transmitted from the supplicant node to the third node.

摘要： The proposed multicast architecture for multi-hop wireless mesh networks enables the mesh networks to join the global multicast group seamlessly, and extend the multicast support to any routable or non-routable devices in the wireless mesh networks. A communications network comprising a plurality of wireless devices (WRD), at least one Internet access point (LAP), and at least one Internet edge router. The Internet access point acts as a proxy device for wireless devices that are using the Internet access point to access a global Internet, wherein the Internet access point runs a group management protocol with a Internet edge router to register multicast groups for devices associated with the Internet access point (220), and wherein the Internet edge router runs a wired multicast routing protocol to join the Internet edge router to a global Internet multicast group (210).

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.

摘要： Disclosed are methods including a new optimization criterion, Maximum Mesh Coverage (MMC) for a channel selection process during the formation of ad hoc networks. By using MMC, the intelligent access point (IAP) will select a channel to connect as many mesh nodes as possible in addition to meeting the interference minimization requirement. During mesh formation, the channel interference information for a node is first scanned by the node and then broadcast in its available channels. An iteration procedure for meshing network formation allows the IAP to gradually obtain the global channel interference information and broadcast the same so that a maximum number of n-hop nodes communicate on the same frequency channel. If a channel change is required to accommodate the channel interference status of candidate nodes, a channel change message will be broadcast to better achieve the large coverage advantage of a multi-hop configuration.
摘要翻译：公开了包括新的优化准则，用于在ad hoc网络的形成期间的信道选择过程的最大网格覆盖（MMC）的方法。通过使用MMC，除满足干扰最小化要求外，智能接入点（IAP）还将选择一个通道来连接尽可能多的网格节点。在网格形成期间，节点的信道干扰信息首先被节点扫描，然后在其可用信道中广播。用于网格形成的迭代过程允许IAP逐渐获得全局信道干扰信息并进行广播，以使最大数量的n跳节点在同一频率信道上通信。如果需要改变信道以适应候选节点的信道干扰状态，则将广播信道改变消息以更好地实现多跳配置的大覆盖优势。
