This paper addresses the problem of managing a wireless sensor network with mobile managers. The mobile managers should be able to create their connectivity to the nodes they manage, and advertise their interests in the management data to be collected. Also, the network nodes should self-manage their connectivity to the managers in order to forward the management data. To meet these requirements, we propose (1) an algorithm for creating and maintaining encounter-associated management

... y and (2) both management data exchange protocols and programming abstractions for network management applications. Both our simulation-based evaluation and experimentation of the proposed algorithm and architectural elements on real sensors demonstrated their effectiveness in meeting the requirements.
