Abstract
Description
本發明係關於感測器網路，尤其係關於感測器網路中的端對端通信。 This invention relates to sensor networks, and more particularly to end-to-end communication in a sensor network.
在工業或民生領域中，感測器網路得到廣泛運用。目前，大部分感測器網路基於ZigBee協定來提供廉價、低功耗和雙向的通信。 In the industrial or people's livelihood field, sensor networks are widely used. Currently, most sensor networks are based on the ZigBee protocol to provide inexpensive, low power, and two-way communication.
由於TCP/IP協定已經成為網際網路中占主導地位的協定，因此，基於TCP/IP協定互連ZigBee網路是不可避免的。此外，由於IPv4中存在許多問題(例如，IPv4位址短缺)，因此，IPv6是用於互聯ZigBee網路的事實上的網路標準。然而，由於ZigBee協定的基本設計與TCP/IP協定不相容，因此，在它們之間提供網路互聯並不容易。例如，由於ZigBee網路中感測器節點的電池壽命較短、體積較小以及因成本較低而導致的儲存空間和CPU速度受限、無線介面複雜度受限等原因，導致了ZigBee網路的資源和能力嚴重受限。由於這些限制，ZigBee網路中的感測器節點無法像IPv6網路中的伺服器 那樣實現IPv6功能。 Since the TCP/IP protocol has become the dominant protocol in the Internet, interconnecting ZigBee networks based on the TCP/IP protocol is inevitable. In addition, due to many problems in IPv4 (for example, IPv4 address shortage), IPv6 is the de facto network standard for interconnecting ZigBee networks. However, since the basic design of the ZigBee protocol is incompatible with the TCP/IP protocol, it is not easy to provide Internet connectivity between them. For example, ZigBee networks are caused by the short battery life, small size, and limited storage space and CPU speed of the sensor nodes in the ZigBee network due to low cost and limited wireless interface complexity. The resources and capabilities are severely limited. Due to these limitations, the sensor nodes in the ZigBee network cannot be like the servers in the IPv6 network. This implements IPv6 functionality.
基於上述缺陷，在ZigBee網路和IPv6網路之間提供一種新的網路互聯方案從而在感測器網路中提供端對端的通信是十分有利的。 Based on the above shortcomings, it is advantageous to provide a new network interconnection scheme between the ZigBee network and the IPv6 network to provide end-to-end communication in the sensor network.
為了在IPv6網路的伺服器和感測器網路的感測器節點之間提供端對端通信，在網路加入過程中，由感測器網路中的閘道為每個感測器節點分配一個全局唯一的虛擬IPv6位址，該虛擬IPv6位址是基於該感測器節點的MAC位址和該閘道的IPv6網路前綴生成的，例如，該虛擬IPv6位址可以一個是由該感測器節點的64bit的MAC位址和該閘道的64bit的IPv6網路前綴結合生成的128bit的位址。 In order to provide end-to-end communication between the server of the IPv6 network and the sensor nodes of the sensor network, each sensor is used by the gateway in the sensor network during the network join process. The node allocates a globally unique virtual IPv6 address, which is generated based on the MAC address of the sensor node and the IPv6 network prefix of the gateway. For example, the virtual IPv6 address may be one The 64-bit MAC address of the sensor node and the 64-bit IPv6 network prefix of the gateway combine to generate a 128-bit address.
由於每個感測器節點被分配了一個虛擬IPv6位址，因此，從IPv6網路中的伺服器的角度來看，該感測器節點就相當於一個普通的IPv6節點。 Since each sensor node is assigned a virtual IPv6 address, the sensor node is equivalent to a normal IPv6 node from the perspective of the server in the IPv6 network.
為了在感測器網路的感測器節點和IPv6網路的伺服器之間提供端對端通信，在網路加入過程中，由感測器網路中的閘道為每個想與感測器節點通信的IPv6伺服器分配一個ZigBee短位址，例如，16bit的ZigBee短位址。該ZigBee短位址在該感測器網路中是唯一的。 In order to provide end-to-end communication between the sensor node of the sensor network and the server of the IPv6 network, during the network joining process, the gateway in the sensor network is used for each sense. The IPv6 server communicating with the test node allocates a ZigBee short address, for example, a 16-bit ZigBee short address. The ZigBee short address is unique within the sensor network.
由於IPv6伺服器被分配了一個ZigBee短位址，因此，從感測器網路中的感測器節點的角度來看，該IPv6 伺服器就相當於一個普通的感測器節點。 Since the IPv6 server is assigned a ZigBee short address, the IPv6 is from the perspective of the sensor node in the sensor network. The server is equivalent to a normal sensor node.
