Wireless sensor networks have proved to be useful in several applications, such as environment monitoring and perimeter surveillance. In a large sensor network, in-network data aggregation (i.e., combining partial results at intermediate nodes during message routing) significantly reduces the amount of communication and energy consumption. Recently, the research community has proposed a robust aggregation framework called synopsis diffusion which combines multi-path routing schemes with duplicate-insensitive algorithms to accurately compute aggregates (e.g., Count, Sum) in spite of message losses resulting from node and transmission failures. However, this aggregation framework does not address the problem of false sub-aggregate values contributed by compromised nodes resulting in large errors in the aggregate computed at the base station, which is the root node in the aggregation hierarchy. This is an important problem since sensor networks are highly vulnerable to node compromises due to the unattended nature of sensor nodes and the lack of tamper-resistant hardware. In this dissertation, we make the synopsis diffusion approach secure against attacks in which compromised nodes contribute false sub-aggregate values. In particular, we present two classes of algorithms to securely compute Count or Sum. First, we propose a lightweight verification algorithm which enables the base station to determine if the computed aggregate includes any false contribution. Second, we present attack-resilient computation algorithms which can be used to compute the true aggregate by filtering out the contributions of compromised nodes in the aggregation hierarchy. Thorough theoretical analysis and extensive simulation study show that our algorithms outperform other existing approaches. This dissertation also addresses the security issues of in-network computation of Median and presents verification algorithms and attack-resilient computation algorithms to securely compute an approximate estimate of this aggregate. To the best of our knowledge, prior to this dissertation there was no other work related to the security of in-network computation of Median. We evaluate the performance and cost of our algorithms via both analysis and simulation. The results show that our approach is scalable and efficient.

WSNs are formed by sensor nodes that have the ability to sense the environment, process the sensed information, and communicate via radio without any additional prior backbone infrastructure. In WSNs, communication with other nodes is the most energy consuming task. Hence, the primary objective in designing protocols for WSNs is to minimize communication overhead. This is often achieved using in-network data aggregation. As WSNs are often deployed in open environments, they are vulnerable to security attacks. This thesis contributes toward the design of energy efficient secure and privacy preserving data aggregation protocol for WSNs. First, we classify the main existing secure and privacy-preserving data aggregation protocols for WSNs in the literature. We then propose an energy-efficient secure and privacy-preserving data aggregation (ESPPA) scheme for WSNs. ESPPA scheme is tree-based and achieves confidentiality and privacy based on shuffling technique. We propose a secure tree construction (ST) and tree-reconstruction scheme. Simulation results show that ESPPA scheme effectively preserve privacy, confidentiality, and has less communication overhead than SMART. Finally we propose an extension of ST scheme, called secure coverage tree (SCT) construction scheme. SCT applies sleep scheduling. Through simulations, we show the efficacy and efficiency of the SCT scheme. Beside the work on secure and privacy preserving data aggregation, during my research period, we have also worked on another interesting topic (i.e., composite event detection for WSNs). Appendix B presents a complementary work on composite event detection for WSNs.

The Wireless Sensor Networks (WSNs) are composed of a huge number of sensor nodes. The large number of nodes may lead to a huge amount of data in the network, causing the network to degrade performance and shorten its lifetime. The data aggregation techniques may be a solution to remane the redundancy of data and thereby reduce the number of packets transmitted in the network. Nevertheless, the data aggregation causes some security vulnerabilities: impersonation, denying having received data, dropping packets deliberately, alteration of the sensored readings and aggregation results... In this report, we compare the performances get by two secure aggregation solutions: the Secure Aggregation for Wireless Networks (Hu et al. protocol) and the Secure Aggregation Protocol for Cluster-Based Wireless Sensor Network (SAPC). The analysis shows that Hu et al. protocol gives better performance than SAPC in terms of number of exchanged messages but it is vulnerable to simple attacks. This report describes both protocols and their performances and propose a new protocol based on binary trees and delayed aggregation result checking to improve the performance of SAPC.

Wireless Sensor Networks have numerous nodes with limited energy in a particular area. One of the major issues in WSN is increasing the network life time. Secure data aggregation is a challenging task in Wireless Sensor Network. This issue needs to be overcome using efficient technique. An energy efficient scheme needs to be proposed to detect the shortest path for data transmission using fuzzy logic. The Sensor Nodes death frustrates and the problem gets aggravated if the cluster node fails. When a cluster node fails because of energy depletion an alternative cluster needs to be chosen for that particular region. In periodical time each sensor node in the cluster should possess the next cluster head re-election based on energy to avoid node failure. In this project a novel technique is proposed using Fuzzy to find the shortest path for data aggregation. It is shown that the proposed technique has improved the throughput with reduced packed drop and also less energy consumption in these networks. The technique is evaluated through NS2.
