Study of Network model and Lightweight trust management scheme in case of trust decision-making.

Abstract

In has been considered that sensor network’s safety measures have been built upon non realistic
trusted environment. After analyzing the trust models for wireless sensor networks it has been found
that there are some issues in resource management. First issue is regarding usage of memory or
RAM management. Second issue is regarding computation overhead or CPU usage. Moreover there
is threat of attacks over wireless sensor network. These attacks may be brute force as well as denial
of service attack. Thus this research considers three issues that are resource management,
computation overhead and security.
Our Proposed model for lightweight trust management scheme in wireless sensor network would
play a significant role in appropriate usage of resources. It would also help in solving issues that has
been raised during computation. It’s dynamic and trust worthy mechanism would meet the
computation overhead issues.
The proposed framework could be proven realistic trust model in have of huge sized wireless sensor
network. It would be safe from different type of attacks. In order to check the malicious activities
that have been performed in nodes, lot for malicious nodes from the total nodes have been managed
by proposed network.
Proposed work has introduced trust metrics in order to consider and schedule the significant tasks of
a sensor node. Here the gang scheduling mechanism has been introduced for scheduling the task. In
this research the advanced adaptive and dual data-communication trust scheme (adct) has been
introduced in case of clustered wireless sensor networks. it would be capable to deal with
untrustworthy nodes in better way. “Unlike prior works, adaptive trust function has been proposed in
order to assess the direct trust among nodes as per application needs. Trust mechanism ADCT has
been proposed at intra-cluster and inter-cluster levels. These requirements are security and
performance by reducing computation overhead packet size reduction by replacing huge words with
mapped key word. Due to this trust model has less overhead during communication and storage as
compared to traditional trust models. The proposed trust model is also providing security against
vulnerabilities using cryptographic mechanisms. The proposed model would be capable to provide
security against on-off attack, badmouthing attack. Moreover the work is also considering issues
regarding selfish nodes and malicious nodes”.
