Energy-Efficient and Secured Mobile Agent Itinerary Approach in Wireless Sensor Network

摘要

In wireless sensor network, mobile agent (MA) paradigm is the substitute which has many advantages over client-server paradigm. As energy consumption is the major issue for research in WSNs, MA-based paradigm has been a boon in resolving this. In spite of sending data from all nodes to sink, mobile agent itself migrates to all the sensor nodes and collects data which results in minimized energy and bandwidth consumption. But for better efficiency, it is required to plan the itinerary in a best way so that MA can collect data from source nodes efficiently. Many algorithms have been given by researchers which consider all sensor nodes to be visited by MA which is incompetent, and none of the algorithm considers the detection of malicious node and preventing mobile agent to migrate to malicious nodes. Proposed algorithm, first stores the device signature of all intended participating sensor nodes, cluster formation, and eventually by authenticating the nodes based on fingerprints an itinerary for MA will be designed. Cluster head nodes are traversed excluding MNs in CHs itinerary, and data will be aggregated from benign nodes only.
