A new mobile agent-based middleware system design for Wireless Sensor Network

Wireless Sensor Network is playing a crucial role in daily life because of its distributed sensing ability in combination with wireless communication techniques and self-organising deployment approaches. To satisfy requirements of easily matching diversified dynamic sensing applications and highly heterogeneous sensor platforms from perspective of logistics, a low budget but high-efficient wireless sensor network middleware is in dire need. To maximise commercial benefits, a WSN middleware is designed in order to increase efficacy and return on investment. This paper presents a design of an inventive mobile agent-based middleware, which could optimally achieve the intensive requirements of a WSN middleware. The middleware proposed in this paper has considered resources limitation issues that are commonly addressed on normal sensor nodes, meanwhile it provides a possibility of platform independence as well as programming language independence. In addition, a mobile agentbased system can reduce network payload and dynamically adapt to environmental changes. Therefore, the middleware presented in this paper has ability of perceiving changes in operating environment and ability to automatically response to these changes.
