In this paper, we present a distributed incremental data aggregation approach, in which data aggregation is performed at all smart metres involved in routing the data from the source metre to the collector unit. With a carefully constructed aggregation tree, the aggregation route covers the entire local neighbourhood or any arbitrary set of designated nodes with minimum overhead. To protect use...

This paper presents a model of a MAS framework for dynamic aggregation of population health data for research purposes. The contribution of the paper is twofold: First, it describes a MAS architecture that allows one to built on the fly anonymized databases from the distributed sources of data. Second, it shows how to improve the utility of the data with the growth of the database.

WSN is often deployed in unattended or even hostile environments. Therefore, providing security in WSN is a major requirement for acceptance and deployment of WSN. Furthermore, establishing trust in a clustered environment can provide numerous advantages. We proposed a light-weighted trust model which consider data aggregation and detailed the data in parameters to depend against attacks. With ...

Although structure...

— The predominate traffic patterns in a wireless sensor network are many-to-one and one-to-many communication. Hence, the performance of wireless sensor networks is characterized by the rate at which data can be disseminated from or aggregated to a data sink. In this paper, we consider the data aggregation problem. We demonstrate that a data aggregation rate of log n n () is optimal and that th...

In this paper, a Reduce Identical Composite Event Transmission (RICET) algorithm is proposed to solve the problem of detecting composite events in wireless sensor networks. The RICET algorithm extends the traditional data aggregation algorithm to detect composite events, and this algorithm can eliminate redundant transmission and save power consumption, thereby extending the lifetime of the ent...

Recently, underwater wireless sensor network is one of the popular research topics to scientist. There are many novel methodologies to reach the goal of the effectiveness network performance such as cluster-based structure, in-network data aggregation, etc. In this paper, we assume the network is clustered by a specific clustering scheme. Then, we suggest a new geographicaldata-aggregation meth...

In this paper, we revisit the private κ data aggregation problem, and formally define the problem’s security requirements as both data and user privacy goals. To achieve both goals, and to strike a balance between efficiency and functionality, we devise a novel cryptographic construction that comes in two schemes; a fully decentralized construction and its practical but semi-decentralized varia...

The most important challenge in wireless sensor network is to reduce the energy consumption of each node and increase the network lifetime. Many networking schemes are used to minimize the amount of data transmission by data aggregation. Three main factors affecting the lifetime of sensor nodes are as follows: (1) the consumed energy for sending data from the leaves to the sink, (2) queuing del...

In-network data aggregation is essential for wireless sensor networks where energy resources are limited. In a previously proposed data dissemination scheme (directed diffusion with opportunistic aggregation), data is opportunistically aggregated at intermediate nodes on a lowlatency tree. In this paper, we explore and evaluate greedy aggregation, a novel approach that adjusts aggregation point...
