Wireless Sensor Network (WSN) consists of low power sensor nodes. Energy is the main constraint associated with the sensor nodes. In this paper, the authors propose a cluster based multipath routing protocol, which uses the clustering and multipath techniques to reduce energy consumption and in-crease the reliability. The basic idea is to reduce the load of the sensor node by giving more responsibility to the base station (sink). The authors have implemented and compared the protocol with existing protocols and found that it is more energy-efficient and reliable.
