Abstract

On-air access of individual sensor node (called remote control) is an indispensable function in operational wireless sensor networks, for purposes like network management and real-time information delivery. To realize reliable and efficient remote control in a wireless sensor network (WSN), however, is extremely challenging, due to the stringent resource constraints and intrinsically unrealizable wireless communication. In this paper, we propose TeleAdjusting, a ready-to-use protocol to remotely control any individual node in a WSN. We develop a coding scheme for addressing on the cost-optimal reverse routing tree. In the address of each node, all its upstream relaying nodes are implicitly encoded. Then through a distributed prefix matching process between the local address and the destination address, a packet used for remote control is forwarded along a cost-optimal path. Moreover, TeleAdjusting incorporates opportunistic forwarding into the addressing process, so as to improve the network performance in terms of reliability and energy efficiency. We implement TeleAdjusting with TinyOS and evaluate its performance through extensive simulations and experiments. The results demonstrate that compared to the existing protocols, TeleAdjusting can provide high performance of remote control, which is as reliable as network-wide flooding and much more efficient than remote control through a pre-determined path.

远程调节:利用路径编码和机会转发实现无线传感器网络的远程控制

单个传感器节点的空中访问(称为远程控制)是可操作无线传感器网络中不可缺少的功能，用于网络管理和实时信息传递。然而，由于无线传感器网络资源的严格限制和无线通信本身的不可实现性，在无线传感器网络中实现可靠、高效的远程控制是极具挑战性的。在本文中，我们提出了teleadjustment，这是一种随时可用的协议，可以远程控制WSN中的任何单个节点。我们开发了一种在成本最优的反向路由树上寻址的编码方案。在每个节点的地址中，它的所有上游中继节点都被隐式编码。然后，通过本地地址和目的地址之间的分布式前缀匹配过程，使用于远程控制的数据包沿着成本最优的路径转发。此外，teleadjustting在寻址过程中加入了机会转发，从而在可靠性和能效方面提高了网络性能。我们利用TinyOS实现了teleadjustment，并通过大量的仿真和实验对其性能进行了评估。结果表明，与现有协议相比，tele调整可以提供高性能的远程控制，其可靠性与全网泛洪一样高，并且比通过预先确定的路径进行远程控制要高效得多。
