LACON: localized autonomic configuration in pervasive sensor networks

Iqbal, Mudasser; Gondal, Iqbal and Dooley, Laurence (2004). LACON: localized autonomic configuration in pervasive sensor networks. In: IEEE Intelligent Sensors, Sensor Networks and Intelligent Processing Conference (ISSNIP’04), 14-17 Dec 2004, Melbourne.




The success of a pervasive sensor network (PSN) of ubiquitous loco-dynamic devices mainly depends on its ability to configure itself according to the environment and the available resources to achieve optimum performance. This self configuring property is indispensable as ad hoc devices are usually exposed to natural or man-made disasters due to the hostile deployment of such networks. The most common dynamics posing a reconfiguration requirement are addition, failure and replacement of critical component devices. In addition to self configuration, the network must be able to monitor these dynamics in an autonomous way in order to take proactive measures for smooth re-configuration of the network, with minimal degradation in quality of service (QoS) provision. The paper presents a comprehensive model for monitoring and reconfiguring sensor networks and provides measures to mitigate network impairments. The results confirm that the proposed self configuring model adopts optimized design parameters and maintains QoS even for highly ad hoc networks.
