Hierachical structure to distribute fault management tasks

Neighbor coordination: Work with local nodes to determine which nodes are at fault

Cluster based failure detection: Cluster heads detect failures in one-hop range

Monitoring battery status

Load balancing

Fault models

Node malfunction

Network disconnect

Permanent and transient effects

Application software failure

Lack of storage space

Lack of working memory

Only share partial information w/ group and network managers as needed

• E.g., only alert when coverage is critically sparse, rather than giving full, constant updates
