Energy is one of the most important and scarce resources in Wireless Sensor Networks (WSN). WSN



nodes work with the embedded operating system called TinyOS, which addresses the constrains of the



WSN nodes such as limited processing power, memory, energy, etc and it uses the collection Tree



Protocol (CTP) to collect the data from the sensor nodes. It uses either the four-bit link estimation or Link



Estimation Exchange Protocol (LEEP) to predict the bi directional quality of the wireless link between



the nodes and the next hop candidate is based on the estimated link quality. The residual energy of the



node is an important key factor, which plays a vital role in the lifetime of the network and hence this has



to taken as one of the metric in the parent selection. In this work, we consider the remaining energy of the



node as one of the metric to decide the parent in addition to the link quality metrics. The proposed



protocol was compared with CTP protocol in terms of number of packets forwarded by each node and



packet reception ratio (PRR) of the network. This work was simulated in TOSSIM simulator and the same



was tested in Crossbow IRIS radio test bed. The results show that our algorithm performs better than



CTP in terms of load distribution and hence the increased lifetime
