Resource-aware task scheduling in wireless sensor networks
Tim De Pauw · Ghent University Academic Bibliography (Ghent University) · 2010
Wireless Sensor Networks (WSNs) are computer networks in which resource-constrained sensor equipment, which communicates over the air, is installed alongside more traditional machines. Applications include home automation and military scenarios. In order for such networks to operate autonomously, the applications deployed on them must be able to cope with their heterogeneity: sensor devices are far less suited for heavy computation, but their mobility is an asset powerhouse servers do not have. At the same time, energy efficiency is a key issue. Distributing workloads over the topology at hand is therefore subject to many constraints. Moreover, operations carried out in a sensor network can be modeled as a sequence of tasks. To order these efficiently while taking into account the constraints described above, scheduling algorithms will be devised and evaluated.
