Abstract
Resources are assigned in a network of sensor nodes by a first sensor node of the network detecting an event and collecting data samples for the event, exchanging messages with other sensor nodes of the network that detect the event to form a community of sensor nodes. Based on information exchanged, the total data samples collected for the event is calculated and the community sends a help message to other sensor nodes. The other sensor nodes are assigned to cover the event if the potential marginal gain if they were to cover the event exceeds a threshold. The potential marginal gain comprises the expected change in a utility function that is dependent upon the total data samples collected for the event by the community. The utility function is a concave function of the total data samples and may be dependent upon an importance level of the event.
