Abstract:
This paper deals with reconfigurable wireless sensor networks RWSN that should be adapted to their environment under user and energy constraints. A RWSN is assumed to be composed of a set of communicating nodes such that each one executes reconfigurable software tasks to control local sensors. We propose three reconfiguration forms to adapt a RWSN: (a) software reconfiguration allowing the addition/ removal/ update of tasks, (b) hardware reconfiguration allowing the activation/deactivation of nodes, (c) protocol reconfiguration allowing the modification of routing protocols between nodes. We propose a zone-based multi-agent architecture
for RWSN where a communication protocol is well-defined to optimize distributed reconfigurations. Each agent of this architecture is modeled by nested state machines in order to control the problem complexity. The paper’s contribution is applied to a case study that we simulate to show the originality of this new architecture.
