In wireless sensor networks, sensor nodes may fail due to energy depletion or physical damage. To recover the data of a failed node, we propose a fault recovery scheme which enables the remaining alive sensor nodes to use the redundant information with regard to the failed node to fulfill the...

Trip planning queries are considered an important part of Location Based Services. As the first part of our research, we investigated Sequenced Group Trip PLanning Queries (SGTP) queries. Given a set of source locations and destinations for a group of n users, and a sequence of Categories of...

Recently, Wireless Sensor Networks (WSNs) have been used in many monitoring applications, e.g., environment monitoring. A WSN consists of a set of nodes, each having one or more sensors to measure a phenomena. Nodes are connected to each other using wireless radio communications. Typically, there...

Delay Tolerant Mobile Networks (DTMNs) provide communication despite the occasional presence of disconnected subnetworks. They rely on finding a set of sequential opportunistic encounters between pairs of mobile nodes. In this context, understanding mobile node behaviour is essential to design...

In this thesis, we propose a novel approach to detect malicious executables in the network layer using a combination of techniques from bioinformatics, data mining and information retrieval. This approach requires translating malicious code into genome-like representations. Based on their...
