Abstract
Recent years, there appears great demands for an inexpensive wireless sensor networks for monitoring or control of non-critical function in residential, commercial, health, and industrial applications. The driven factors behind are either for reduction of installation cost or energy consumption, automation (self-configuring), or government regulations. This urges the fast development of Low-Rate Wireless Personal Area Network, and the standard IEEE 802.15.4, a common specification for its physical layer and medium access protocol sub-layer.
We aim at the routing scheme in network layer and propose an energy-efficient routing protocol, applying the Physical Layer (PHY) and Medium Access Control (MAC) specifications for Low-Rate Wireless Personal Area Networks (LR-WPAN) standardized in IEEE 802.15.4 Standard. In our proposed routing protocol, we obtain multiple paths after one route request when first time the traffic session was initiated. During network operation, we deploy small packets as probing agents, sampling those multiple paths’ condition (in this paper, we sample conditions of devices’ residual energy along each path), and accordingly help the source to decide which candidate path to route for coming data packets.
