路由协议在无线传感器网络的设计和正确使用中起着重要的作用，它克服了互连网络的所有限制。由于无线传感器网络的真实的应用，路由协议的作用变得更加具有挑战性。传感器节点的寿命长，需要有效地使用路由协议，可以通过保存能量。数据中心、层次和位置是路由协议设计的三种不同类型，也是路由协议设计的具体方法。其他一些挑战被称为竞争，其中许多节点访问介质。因此，在这种情况下，数据包之间会发生冲突。在无线传感器网络中，还没有一种方法可以发现这些类型的冲突。自干扰也是传感器网络面临的挑战之一，它发生在连续的跳数中。动态性问题是指在较短的时间内，链路发生多次失效和追赶，链路的质量也随着时间的推移而发生变化。在无线传感器网络中，有许多参数控制着传输速率、传输功率等，数据传输时间也影响着网络的能量节约和服务质量（QOS）。
The routing protocols are playing a major role in the design and proper utilization of wireless sensor networks (WSN) that overcome all the limitation of interconnection networks. The role of routing protocols is become more challenging due to the real time applications in WSNs. The long life of sensor nodes is required for efficient use routing protocols which can be possible by preserving energy. Data Centric, Hierarchical and location are the three different kinds of categories is used in the design of routing protocols which is also approaches specific. Some other challenges are spoken of as contention in which many nodes access the medium. So the clash between packets would take place in this scenario. There is no method to find out these types of the collisions in WSN. Self-interference is also one of the challenges of the sensor network which is occurred in successive hops. The problem of dynamism is in that the links failure and catch up with for several times in lesser time and qualities of links are also changed during time. There are many numbers of the parameters which handles transmission rate, transmission power, etc. The data transmission time also impacts on the energy conservation and quality-of-service (QOS) in wireless sensor network.
