Data gathering is a common but critical operation in many applications of wireless sensor networks. The innovative techniques that improve energy efficiency to prolong the network lifetime are highly required. As a novel information acquiring and processing technology, multimedia sensor networks, in contrast to the traditional sensor networks, pay more attention to the multimedia data (e.g., audio, image and video). However, the traditional sensor nodes with low power and small storage are not suitable for in-network processing and storing in data centric applications. We propose CBSM, a new collaboration based storage management scheme in wireless multimedia sensor networks, which better suits the random event sensing and data gathering; furthermore, it applies a novel resource-based method to balancing the energy and storage consuming among nodes, which adjusts packet size in communication dynamically to prolong the network lifetime. Our experiments demonstrate that CBSM can improve the network lifetime drastically even using the existing energy-constraint and storage-constraint sensor nodes.
