The wireless sensor network is the self configuring type of network which can be used to sense environmental conditions like temperature, pressure etc. The main issue in wireless sensor network is the battery consumption as it is very difficult to recharge or replace battery of sensor nodes. To increase lifetime of the sensor networks technique of clustering will be applied in which static and dynamic clustering techniques will be applied. In the previous technique, opportunistic based routing is proposed for data routing in wireless sensor networks, in which the source node store the data on the intermediate node which will move near to the base station and deliver data to the base station. The data which is stored on the intermediate node also given the priority and data which has higher priority is delivered first to base station. In this paper, we discuss some research challenges in an opportunistic based routing.
