We address security solutions to protect the communication of the wireless components of a home health care system. We analyze especially the problem of exchanging secrets to sati...
Message aggregation can be used to reduce the communication overhead in a network where many messages have the “same” content. However, it may make the network less secure bec...
In-network aggregation is an essential primitive for performing queries on sensor network data. However, most aggregation algorithms assume that all intermediate nodes are trusted...
Information aggregation is an important operation in wireless sensor networks executed for the purpose of monitoring and reporting of the environmental data. Due to the performance...
This paper presents a secure alternate path routing in sensor networks. Our alternate path scheme makes the routing protocol resilient in the presence of malicious nodes that laun...
