Abstract:

A large part of the energy budget of traditional sensor networks is consumed by the hop-by-hop routing of the collected information to the static sink. In many applications it is possible to replace the static sink with one or more mobile sinks which move in a sensor field and collect the data through one hop transmissions. This greatly reduces the power consumption of the nodes, which can be further reduced by the choosing the appropriate moment of transmission. In general, the transmission energy increases quickly with the distance, thus it makes sense for the nodes to transmit when one of the mobile sinks is in close proximity. One of the side effects of the one-hop transmission is that the node is responsible only for its own data and its own energy resources. Thus, it makes good sense to treat the sensor node as an autonomous agent which maximizes the utility of the collected and transmitted data, while minimizing the energy expenditure. This paper proposes several approaches for such an agent controlled sensor node. As the basis of comparison, we describe a dynamic programming-based approach for the optimal policy in the context of full world knowledge. Then, we describe and compare three heuristics based on different principles (imitation of human decision making, stochastic transmission and constant risk). We compare the proposed approaches in an experimental study.
