We consider the problem of data dissemination in a sensor network. First we introduce a cost model for data dissemination in such networks. The model quantifies the tradeoff between the inconsistency of the data, and its transmission cost; the transmission cost is given in terms of energy and bandwidth. Then we introduce a novel broadcast policy, ABR, that utilizes our cost model. In the ABR policy, each sensor broadcasts updates only if the cost of sending is justified by (its view of) the current level of inconsistency. Data received from other sensors are rebroadcast using the same cost measures. Finally we compare the performance of ABR with that of several existing data dissemination policies. Via the comparison we discover an intricate interplay among the various parameters in choosing a dissemination policy.
