Wireless Sensor Networks (WSNs) are a recent promising technology used to facilitate the provision of many civilian, military, and industrial services. Many challenges hinder the effective use of WSNs to support different applications, such as the resource limitations of sensor devices and the finite battery power. This paper proposes a new routing protocol that considers sensors power limitation and prolongs the network's lifetime by avoiding excessive messages between nodes. This protocol is based on Tree Routing (TR). It routes the data over the shortest path using parent-child links in accompany with neighbors' links. Also, it solves the problem of node's failure. The proposed protocol is analyzed and compared with other tree-based routing protocols.
