Wireless Sensor Networks (WSNs) are composed of battery powered small sensor nodes with limited processing, memory and energy resources. Self organization property together with infrastructureless characteristics of WSNs make them favorable solutions for many applications. Algorithms and protocols developed for WSNs must consider the characteristics and constraints of WSNs but since battery replenishment is not possible or highly challenging for sensor nodes, one of the major concerns in designing network protocols and algorithms is to achieve energy e ciency and to extend the network lifetime. Hence, energy e cient solutions are required for routing and security problems in WSNs. In this dissertation, we model and analyze several routing and security problems in WSNs. We first study the impact of spatial granularity of measurements on the energy requirements of sensor network. We then investigate the energy cost of survivability in the presence of physical attacks. We next study the impact of the number of routing paths on network wide energy balancing under optimal operating conditions. Finally, we investigate the energy cost of route diversity to improve the security of WSNs against adversaries attempting to obtain sensitive sensor data. We contribute to the literature by developing novel mathematical programming frameworks and presenting a comprehensive high level analysis of the several routing and security problems in WSNs. The novel mathematical programming frameworks presented in this thesis can be used with minor modifications for future analysis of di erent routing and security problems in WSNs.

Life time sensitive weighted clustering on wireless sensor networks
Alizadeh Jarchlo, Elnaz; Bazlamaçcı, Cüneyt Fehmi; Department of Information Systems (2013)
Wireless Sensor Networks typically include wireless sensor nodes with limited energy. Network lifetime and scalability are considered as two significant requirements for sensor network applications. In order to decrease energy consumption and increase network lifetime one can apply an efficient clustering method. The application of the clustering method proposed in this thesis (LTS-WCA) leads to reducing the energy cost and the transmission distance of each node by grouping the nodes in several clusters and...
Communication Coverage in Wireless Passive Sensor Networks
Bereketli, Alper; Akan, Ozgur B. (2009-02-01)
System lifetime of wireless sensor networks (WSN) is inversely proportional to the energy consumed by critically energy-constrained sensor nodes during RF transmission. In that regard, modulated backscattering (MB) is a promising design choice, in which sensor nodes send their data just by switching their antenna impedance and reflecting the incident signal coming from an RF source. Hence, wireless passive sensor networks (WPSN) designed to operate using MB do not have the lifetime constraints of convention...
Immune system based distributed node and rate selection in wireless sensor networks
Atakan, Baris; Akan, Ozguer B. (2006-12-13)
Wireless sensor networks (WSNs) are event-based systems that rely on the collective effort of dense deployed sensor nodes. Due to the dense deployment, since sensor observations are spatially correlated with respect to spatial location of sensor nodes, it may not be necessary for every sensor node to transmit its data. Therefore, due to the resource constraints of sensor nodes it is needed to select the minimum number of sensor nodes to transmit the data to the sink. Furthermore, to achieve the application-...
Exploiting energy-aware spatial correlation in wireless sensor networks
Shah, Ghalib A.; Bozyigit, Muslim (2007-01-12)
Wireless sensor networks (WSNs) promise fine-grain monitoring in a wide variety of applications, which require dense sensor nodes deployment. Due to high density of nodes, spatially redundant or correlated data is generated. Redundancy increases the reliability level of information delivery but increases the energy consumption of the nodes too. Since energy conservation is a key issue for WSNs, therefore, spatial correlation can be exploited to deactivate some of the nodes generating redundant information. ...
Impacts of Routing Attacks on Surveillance Wireless Sensor Networks
Sert, Seyyit Alper; Yazıcı, Adnan; Coşar, Ahmet (2015-08-25)
Surveillance Wireless Sensor Networks (SWSNs) are the result of abundant data gathering requirements occurring in Wireless Sensor Networks, specifically for surveillance reasons. Most SWSNs operate by sensing the environment and transmitting the acquired data to a sink in order to utilize it for decision making processes such as object detection, classification, localization, or event detection. In this respect, secure routing of acquired data is crucial since a decision making process is performed accordin...
