Energy Aware and Link Quality Based Routing in Wireless Sensor Networks under TinyOS-2.x
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 3
Abstract
Abstract: In WSN the size of sensor node is too small and in future it will become smaller and energy is one of the constraints in sensor node in WSN. In sensor node energy required to process data,transmitting data and receiving data. Communication requires more energy than processing data. Tiny OS is embedded operating system in sensor node. In TinyOS 2.x there is routing protocol called collection tree protocol. Collection tree protocol finds the route according to link quality. But residual energy is key factor in sensor node. The proposed routing protocol improves routing mechanism in collection Tree protocol by energy based routing. The proposed algorithm (ELR) was compared with CTP protocol in terms of packet reception ratio (PRR) and number of nodes alive ratio of the network. This work was simulated in Castalia 3.2 and TOSSIM simulator. The results show that our algorithm performs better than CTP in terms of loaddistribution and increased lifetime.
