82 An Energy aware Query Based Routing algorithm for Wireless Sensor Networks Shohreh Ahvar s ahvar@ec iut ac ir Date of submition 19 8 2012 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan Iran Language Farsi Degree M Sc Supervisor Mehdi Mahdavi m mahdavi@cc iut ac ir Abstract Wireless Sensor Networks WSNs have drawn considerable attention in recent years due to their potential applications These applications include monitoring active volcano eruption monitoring the stability of dams bridges and roads monitoring sensitive areas of military battlefield and planetary exploration projects such as lunar exploration for water ice WSNs are Ad hoc wireless networks which consist of a large number of densely deployed miniature disposable sensor nodes in the region of interest to monitor and capture physical environmental conditions such as pressure temperature humidity etc In such a network environmental data is transmitted in multi hop manner to the base station sink node for further processing through a wireless link As the sensors placement can be random such nodes can be placed in dangerous or inaccessible places Since the sensors are battery powered devices energy efficiency is considered as one of the main factors in designing routing protocols in WSNs Power failure of a node affects the node itself and also its ability to forward packets on behalf of others as well as the overall network lifetime The lifetime of a sensor network can be increased significantly if the operating system MAC layer and the network layer protocols and even higher layers are designed to be energy aware From the energy point of view routing protocols in WSNs are very challenging due to their significant effect on the energy consumptions of nodes This is because a routing protocol is responsible to deliver data packets in an infrastructure less network with a large number of nodes which might have mobility The routing protocols can be divided into five categories including multipath based query based negotiation based QoS based and coherent based In recent years various energy efficient routing protocols have been proposed to increase the networks lifetime Methods for increasing lifetime of sensor networks through the routing protocols are divided into two categories In the first category the routing protocols try to reduce the
