Abstract:
This paper introduces a new algorithm for
calculating trust in Wireless Sensor Networks
based on the quality of services characteristics
expected to be fulfilled by nodes. Figure 3
shows the algorithm being proposed as a
flowchart. The flowchart shows the three main
sources for computing trust; the previous
experience with the nodes, the
recommendations from the surrounding nodes
and the dispositional trust in nodes (the
amount of risk the node is ready to take in the
absence of the previous experience and/or the
recommendations). Wireless Sensor Networks
as an emerging technology has received a
great attention from both, researchers and the
industry due to the need of tiny and cheap
nodes to be distributed in large scales and in
difficult environments. The creation, operation,
management and survival of Wireless Sensor
Networks as a special type of ad hoc network
is dependent upon the cooperative and trusting
nature of its nodes.
