A review on efficient routing techniques in wireless sensor networks

In the 21^st century, smart environment wireless sensor networks have become an integral part of our lives. These wireless sensor networks contain large numbers of computing devices i.e. motes, but it has a very limited battery life-time and communication abilities (i.e. capacity, bandwidth etc.). So energy and routing are also major issues for wireless sensor networks. Most of the researchers use different techniques to increase the performance of wireless sensor networks in terms of network lifetime and using different routing protocols. We propose the multi-hop neighbor information technique by using shortcut tree routing protocol in wireless sensor networks. This review paper describes the multi-hop neighbor information technique and routing protocol methodologies which enhance the performance of WSN´s.
