Embodiment

[0049] First introduce the experimental environment of this experiment: the network environment used in this experiment is the famous wireless mobile ad hoc network simulator Glomosim, which can simulate the environment of wireless mobile ad hoc network. The method based on the number of hops, the improved method based on the number of hops and the method of the present invention considering the node life cycle are evaluated.

[0050]In the simulation experiment, it is assumed that each node in the network has the same energy at the beginning, and the energy consumed by each node to transmit the service request packet and execute the service is also the same, and each node is executing the service The time is also the same, and every node in the network knows the path to a particular service-providing node. Some parameters in the experiment can be seen in Table 1 below.

Abstract

The invention belongs to the technical field of self-organization networks, and relates to a service selection method in a wireless mobile self-organization network. The method comprehensively considers three factors of service number of nodes in the network, energy consumed by a relay node transmission service request packet and energy consumed by a service execution node to execute service through Cost function; the most suitable service provision node is selected to execute service request to ensure the maximization of network life cycle, thus solving the technical problem of shorter network life cycle in a selection method based on hop count, and changing limitation problem of the improved service selection method based on the hop count.

Description

technical field [0001] The invention belongs to the technical field of ad hoc networks, and in particular relates to a service selection method in a wireless mobile ad hoc network. 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] In a wireless mobile ad-hoc network, service selection is to select an existing service on the network to execute the service request of the service initiator. The current service selection method in the wireless mobile ad hoc network is blank, and a simple service selection method based on hop count is proposed, but this method will bring a series of problems, for example, for a certain For some Web services, the ...
