Prioritized Redundancy of Data Storage in Wireless Sensor Networks

Wireless sensor networks have evolved into complex deployments, where their nodes can have a full network protocol stack, database systems, etc. The main rationed resource in such a deployment is energy. Having power usage tightly managed ensures a long operational life for the node in cases where replenishments (either via recharge or battery change) are difficult or impossible. The basic deployment of wireless sensor networks consists of sensing nodes as well as a relay node (i.e., sink), which collects sensory data to be relayed via a reliable network.
