Due to the huge potential profit that sensor networks may provide in industrial and socio-economic areas, they attract the attention of many researchers around the world. However, their development level has not reached an acceptable status due to several barriers. Each sensor is equipped with a battery but of limited energy which causes major obstacle on the lifetime of the network. These sensors have communicated with the sink which might be far away. A mobile sink can be considered as an alternative solution to the problems already identified, but it also raises new challenges such as the location of the mobile sink and communication with the sensors. In this paper, we proposed a new robust routing protocol called Tree and Mobile Sink-based Routing Protocol. This protocol is based on the intra-cluster multi-hop concept using a constructed tree for data routing and a new strategy for sink mobility to collect data from cluster heads. In order to evaluate the performance of algorithm, we implemented it using the NS2 network simulator.
