Abstract:

Wireless sensor and actor networks （WSANs） are composed of a large number of sensors and a small number of （mobile） resource-rich actors. Sensors gather irformation about the physical phenomenon while actors make decisions, and then perform appropriate actions upon the environment. The paper studies the allocation of single-actor tasks in WSANs, and proposes two algorithms： a centralized and a distributed algorithm. Finally the algorithms are ev valuated in JSIM.

Key words: wireless sensor and actor network, single-actor task;decision-making, coordination
