Abstract:
Wireless Sensor Networks (WSNs) are the key of gathering the information in a smart
environment. This environment could be a building, utilities, an industrial firm, etc.
WSNs have an endless list of potential applications in both military and civilian fields.
One common feature shared by all of these critical applications, is the vitality of sensor
location. Many techniques have been discussed for sensor localization, the simple one is
based on using a Global Positioning System (GPS). Yet, it's not a feasible solution from
an economic perspective. Therefore, other techniques use the known location beacon
(special sensors) (BNs) to help the other sensors (SNs) to compute there location.
Secure localization in WSNs has become a major focus for researchers in recent years.
Since many intruders exploit the WSNs localization technique. Many secure localization
techniques have been implemented, where the most recent one depends on a smart node
monitoring to exclude any malicious nodes. This paper proposes an applicable Secure
Localization Model (SLM) for excluding malicious BNs to ensure secure localization of
SNs, by enabling BNs to monitor their neighbors, establishing a Neighbor Reputation
table (NRT), and then publish it as a response of the sensor location requests, so as the
SNs can avoid the malicious BNs false location. Our simulation shows that the proposed
SLM provides a simple and applicable secure localization model for WSNs.
