摘要：Wireless sensor networking is an emerging technology that promises a wide range of potential applications in both civilian and military areas. A wireless sensor network (WSN) typically consists of a large number of low - cost, low - power, and multifunctional sensor nodes that are deployed in a region of interest. These sensor nodes are small in size but are equipped with sensors, embedded microprocessors, and radio transceivers. Therefore, they have not only sensing, but also data processing and communicating capabilities. The main task of wireless sensor nodes is to sense and collect data from a target domain, process the data, and transmit the information back to specific sites where the underlying application resides. Achieving this task efficiently requires the development of an energy-efficient routing protocol to set up paths between sensor nodes and the data sink. The path selection must be such that the lifetime of the network is maximized. The characteristics of the environment within which sensor nodes typically operate, coupled with severe resource and energy limitation, make the routing problem very challenging. This paper presents an overview of routing algorithms in wireless sensor networks
