On agent-based aggregation schemes in networks with malicious nodes

چکیده
Mobile agents can be used to efficiently aggregate information in sensor networks. The originator aims at obtaining the correct result, even in the presence of byzantine nodes or a malicious aggregator agent. Secure information aggregation considers these situations. We propose to use a mobile agent for the hierarchical in-network aggregation scheme of Chan et al. and we introduce a greedy strategy to their commitment forest in order to reduce the communication cost of the aggregation process. This approach is promising in particular for a sequence of aggregations.

GGRA: a grouped gossip-based reputation aggregation algorithm
An important issue in P2P networks is the existence of malicious nodes that decreases the performance of such networks. Reputation system in which nodes are ranked based on their behavior, is one of the proposed solutions to detect and isolate malicious (low ranked) nodes. Gossip Trust is an interesting previously proposed algorithm for reputation aggregation in P2P networks based on t...
متن کاملA Genetic Programming-based trust model for P2P Networks
Abstract— Peer-to-Peer ( P2P ) systems have been the center of attention in recent years due to their advantage . Since each node in such networks can act both as a service provider and as a client , they are subject to different attacks . Therefore it is vital to manage confidence for these vulnerable environments in order to eliminate unsafe peers . This paper investigates the use of genetic ...

Communication security of wireless sensor networks is achieved using cryptographic keys assigned to the nodes. Due to resource constraints in such networks, random key pre-distribution schemes are of high interest. Although in most of these schemes no location information is considered, there are scenarios that location information can be obtained by nodes after their deployment. In this paper,...
متن کاملTrust-Based Secure Aggregation in Wireless Sensor Networks
Wireless Sensor networks are often deployed in open environment, thus the networks can be susceptible to their unexpected physical environment and attacks from some adversaries. In addition, sensor devices are limited in resources and vulnerable to node capture, so even a few malicious adversaries can easily compromise sensor devices and inject forged data into the networks to make the networks...
