1 Introduction Wireless sensor networks have made great progress in military reconnaissance, environmental monitoring, medical services, smart home, personnel positioning, industrial and commercial fields. However, with the increasing demand for awareness of the surrounding information, new requirements have been put forward to the wireless sensor network [1]. In typical wireless ad hoc networks, besides the wireless sensor network, it also includes Ad hoc network and so on. The network protocol of wireless sensor originates from Ad hoc network. However, there are many differences and emphasis on the application purposes and use scenarios of these two kinds of self-organizing networks [2]. In addition to the low transmission rate requirements for wireless sensor networks, the network layer routing protocol focused on this paper is discussed as an example. Energy aspects: Energy is not a key problem in the Ah hoc network. However, the wireless sensor network needs to solve the problem of hard work energy supply under the bad environment in the field. The routing algorithm of the traditional Ad hoc network cannot meet its requirements [3]. Network scale aspect: The application of wireless sensor network is often large network with a large number of nodes [4]. A large number of sensor network nodes are also testing the network and routing capabilities of traditional routing algorithms [5]. The continuous changes in the topology of the network structure: Wireless sensor network (WSN) should be able to solve the problem of frequent changes of network structure caused by node failure and movement [6]. In view of the particularity of wireless sensor network application and the special requirements of people to wireless sensor network, at present, the existing network protocols cannot meet the needs of people at present. As a result, the research and improvement of wireless sensor network protocol has been forced in the eyebrow [7].
