A mobile apparatus comprising:

• a cooperator detector configured to select a cooperating mobile apparatus among adjacent mobile apparatuses;
• a cooperation planner configured to determine a cooperation plan for operating cooperative context monitoring with the cooperating mobile apparatus;
• and
• a context processor configured to operate a context monitoring based on the cooperation plan,
• wherein the cooperation planner is configured to generate all possible cooperation cases with the cooperating mobile apparatus, determine expected benefits of the cooperation cases, and select at least one of the cooperation cases based on the expected benefits,
• wherein the cooperation cases include a time sharing cooperation case generated by the mobile apparatus and the cooperating mobile apparatus is configured to alternately operate the context monitoring by dividing monitoring time, and
• wherein when a set of the time sharing cooperation case is CM, the time sharing cooperation case is case_co, a context being able to be provided by the mobile apparatus is S1, a context needed by the mobile apparatus is D1, a context being able to be provided by the cooperating mobile apparatus is S2 and a context needed by the cooperating mobile apparatus is D2, CM=(case_co(ctxco)|ctxcoε(S1∩D1∩S2∩D2)).

A method of cooperative context monitoring, the method comprising:

• selecting a cooperating mobile apparatus among adjacent mobile apparatuses using a cooperator detector of a first mobile apparatus;
• determining a cooperation plan for operating a cooperative context monitoring with the cooperating mobile apparatus using a cooperation planner of the first mobile apparatus;
• and
• operating a context monitoring based on the cooperation plan using a context processor of the first mobile apparatus,
• wherein the determining a cooperation plan includes,
• generating all possible cooperation cases with the cooperating mobile apparatus,
• determining expected benefits of the cooperation cases, and
• selecting at least one of the cooperation cases based on the expected benefits,
• wherein the cooperation cases include a role sharing cooperation case generated by the first mobile apparatus and the cooperating mobile apparatus configured to independently operate context monitoring and share results of the context monitoring, and
• wherein when a set of the role sharing cooperation case is EX, the role sharing cooperation case is case ex, a context provided to the cooperating mobile apparatus is ctxout and a context provided from the cooperating mobile apparatus is ctxin, a context being able to be provided by the first mobile apparatus is S1, a context needed by the first mobile apparatus is D1, a context being able to be provided by the cooperating mobile apparatus is S2 and a context needed by the cooperating mobile apparatus is D2, EX=(case_ex(ctxout, ctxin)|ctxoutε(S1∩D2), ctxinε(D1∩S2), ctxout≠ctxin).
