Motivation

Typically, a WSN performs distributed network computations to meet its specific needs.

Complex network computations demand high processing power within a sensor node.

Collector nodes introduced in [1] are better equipped in terms of processing power and battery consumption than ordinary sensors.

High-valued distributed in-network computations can be achieved by collector nodes‘ collaboration .

Collector nodes represent local neighborhood of sensors to higher hierarchy of WSN.

Proposed Solution

Collector nodes are proposed to apply Mobile Web Services to perform local computations .

Cooperation among the collector nodes would initiate higher-valued Mobile Web Services for complex distributed in-network computations.

Study new fields in the area of Mobile Web Services to identify realistic business and application scenarios .

Scientific Challenges

Network computations in wireless networks.

Organization of cooperative collector nodes owning Mobile Web Services.

Gain a high-valued network based on Mobile Web Services.
