A service-oriented approach for in-network computations in wireless networks

The concept of Mobile Web Services (Mob-WS) is catching pace within research communities due to rapid classification of mobile devices enabling pervasive environments. Beside consumer oriented use cases, another aspect of utilizing the potential of Mob-WS is to use them as computation resources within a wireless network. Such Mob-WS are called ldquoIn-network Mob-WSrdquo. In this paper we propose an approach of using in-network Mob-WS for better management and presentation of wireless networks. A concept of using Mob-WS as back-end resources for in-network computations is presented by proposing a Mob-WS middleware hosting long-lived asynchronous services. With a specialized focus on Wireless Sensor Networks (WSN), a notion of collector nodes is introduced to perform Mob-WS based in-network computations and collaborations enabling control, monitoring and better representation of the network to some node in the higher hierarchy. The In-network computation and service oriented communication requirements are also discussed followed by a proof-of-concept prototype and priliminary performance evaluations.
