A pervasive network consists of heterogeneous devices with different computing, storage, mobility and connectivity properties working together to solve real-world problems. The emergence of wireless sensor networks has enabled new classes of applications in pervasive world that benefit a large number of fields. Routing in wireless sensor networks is a demanding task. This demand has led to a number of routing protocols which efficiently utilize the limited resources available at the sensor nodes. Most of these protocols either support stationary sensor networks or mobile networks. This paper proposes an energy efficient routing protocol for heterogeneous sensor networks with the goal of finding the nearest base station or sink node.
