The commonly unattended and hostile deployments of WSNs and their resource-constrained sensor devices have led to an increasing demand for secure energy-efficient protocols. Routing and data aggregation receive the most attention since they are among the daily network routines. With the awareness of such demand, we found that so far there has been no work that lays out a secure routing protocol...

We present a survey of the various families of approaches to secure aggregation in distributed networks such as sensor networks. In our survey, we focus on the important algorithmic features of each approach, and provide an overview of a family of secure aggregation protocols which use resilient distributed estimation to retrieve an approximate query result that is guaranteed to be resistant ag...

The use of attack-prone hardware makes designing secure schemes for data collection a complex task. Addressing the continuous threat of attacks at the aggregator nodes, this work proposes a privacy preserving secure in-network data aggregation (PPSDA) technique for wireless sensor networks (WSNs). Using the pallier crypto system, a secure scheme which is resilient to false data injection attack...

In Wireless sensor networks, a very common task is that of monitoring a large area in regards to some physical sensed value such as temperature. Usually the end user wants to examine and analyze this information, so they are collect in a central point we call the sink node. Due to the large amount of data transmitted as the scale of the network increases, it is important to combine several sens...

The goal of this paper is to demonstrate inWalk, an interactive web-based system for linked data exploration featured by the notion of inCloud and thematic walk. The demonstration focuses on the key functionalities of the system for smart data aggregation and navigation.

Energy efficiency is the most important issue in all facets of wireless sensor networks (WSNs) operations because of the limited and non-replenish able energy supply. Data aggregation mechanism is one of the possible solutions to prolong the life time of sensor nodes and on the other hand it also helps in eliminating the data redundancy and improving the accuracy of information gathering, is es...

In most wireless sensor networks, applications submit their requests as queries and wireless sensor network transmits the requested data to the applications. However, most existing work in this area focuses on data aggregation, not much attention has been paid to query aggregation. For many applications, especially ones with high query rates, query aggregation is very important. In this paper, ...

Modern wireless sensor networks require specific and high degree of security due to their limitation and versatility tasks. The absence of permanent infrastructure makes these networks suitable for many civilian applications. But their limited computational ability and battery resources restrictions makes them vulnerable to many kinds of attacks. This paper presents reliability in Wireless Sens...

Data aggregation in wireless sensor networks eliminates redundancy to improve bandwidth utilization and energyefficiency of sensor nodes. One node, called the cluster leader, collects data from surrounding nodes and then sends the summarized information to upstream nodes. In this paper, we propose an algorithm to select a cluster leader that will perform data aggregation in a partially connecte...
