A biological signal sensor apparatus worn on a user's body includes: a sensor unit for sensing physical states or movements of a user to generate biological signal data; a wireless communications unit for performing wireless data communications with a wireless sensor network to transmit the biological signal data; a sensor network protocol processing unit for processing protocols for end-to-end communications between the wireless communications unit and the wireless sensor network and for performing a mobility support procedure for the biological signal sensor apparatus; a processor for controlling the wireless data communications, the end-to-end communications, and the mobility support procedure to allow the biological signal sensor apparatus to serve as a mobile wireless sensor node; and a connection unit for connecting the sensor unit and the processor. The biological signal sensor apparatus serves as a mobile wireless sensor node in the wireless sensor network.

Provided is a path-token-based web service caching method including determining whether or not stored cache data exists when a web service call request exists, and when the cache data does not exist, creating a predetermined path-token set and a predetermined tag data set based on a message schema of Web Services Description Language (WSDL), and creating a request Simple Object Access Protocol (SOAP) message, creating a request SOAP message template by using a path-token for the created request SOAP message, and calling the web service, and creating cache data including the tag data set, input values set, the request SOAP message template, the request SOAP message, and SOAP binding information. Accordingly, the method can solve the problems of a conventional web service caching method whereby the method can not cope with change in the number of inputs, and an exact input position is not searched for when an input value is changed. Therefore, it is possible to implement an efficient web service call environment by web service caching.
