Embodiment 1

[0033] On a composite service execution path of C->A->B->C, node C is the composite service initiating node, and nodes A and B are service providing nodes. C initiates a combined request to convert PS documents into PDF format and print them out. Node A provides atomic services for converting PS documents into PDF format documents. Node B provides atomic services for printing out PDF documents. Each node will be described in detail below The execution process 1. The processing process of the service initiation node C:

[0034] a) When the service initiating node C sends a combined service request for format conversion and printing, the user will set a threshold time. If the threshold time is reached, the service initiating node C has not received the result of the service execution, and the user will be notified of the combination Service execution failed;

[0035] b) Service initiating node C is also the monitoring center of atomic service A on the composite service executio...

Abstract

The invention belongs to the technical field of self-organization networks, and relates to a dynamic service recovery method in a wireless mobile self-organization network. The dynamic service recovery method described in the invention is a method based on a dynamic monitoring center. On a predetermined combination service execution path, each service provision node automatically becomes a monitoring center of the next node on the combination service execution path; service executive condition can be rapidly learned with a smaller expenditure by the strategy of the dynamic monitoring center so as to determine whether the service needs to be executed again and be restarted from some service node.

Description

technical field [0001] The invention belongs to the technical field of wireless mobile ad hoc networks, in particular to a dynamic service recovery method in wireless mobile ad hoc networks. Background technique [0002] Wireless mobile ad-hoc network is one of the current research hotspots, and it is also a technical field with broad development prospects. Service computing is also a current research hotspot. Present service computing is all applied in the wired network field. What the present invention relates to is exactly intersection of the above two fields. [0003] The wireless mobile ad hoc network is composed of a group of mobile nodes with wireless transceiver devices, which are temporarily established without depending on the preset infrastructure. Due to the above-mentioned characteristics, the communication nodes in the wireless mobile ad-hoc network are unstable and are easily interfered by external factors, resulting in abnormal interruption of communication....
