Coordination Strategies for Agent Migrations in Wireless Sensor Networks

摘要: Agent-based middleware platforms for wireless sensor networks (WSNs) have received a lot of attention during the last years, due to their great flexibility in re-programming, monitoring, handling, and optimizing application as well whole system. Even though many algorithms been proposed dynamic placement agents within WSN, they do not take into account coordination aspects such migrations. This only may result slow convergence but also perpetual oscillations agent migrations, degrading system performance. In this paper, we propose full-coordination, semi-coordination, non-coordination migration strategies, evaluate network overhead. We provide proofs that is guaranteed when adopt our strategies. Our results show semi-coordination strategy superior terms both overhead rate.
