OVERVIEW OF THE SOLUTION
In those scenarios the use of mobile devices is
mandatory and to communicate them only Ad-
hoc Networking can carry this out.
Mobile agents technology has been proposed
to:
 Reduce the main problems in Ad-hoc Networks
(Power, QoS, BW, etc.).
 Control the communication flow.
 Exchange services and cooperation between Fig.1 Ring of Fault Tolerance

3. PROPOSED SCENARIO 4. SERVICE PROVISIONING IN SAMPLE SCENARIO
A forest fire scenario has been proposed as Once the Ad-hoc network is created and every agent is

 An agent (within a mobile device) is
continuously offering images of the disaster.
 Mobility and nomadic behavior is performed in order to
maintaining services and be aware of safety messages.
