Design of Wireless Sensor Network Node based on OMAPL138 Chip

With the rapid development of sensor and wireless network technology,wireless sensor network would have large application prospects in military and commercial areas. The nodes with perception and routing functions in the wireless sensor network are the elementary units of the whole network. Aiming at the features of sensor network node,and based on dual- core architecture OMAPL138,a wireless sensor network node with low power- consumption and high performance is designed. With the introduction of OMAPL138,the design process and implementation of sensor network node are also described,including the hardware architecture and the software development procedure. This solution could be applied in the construction of wireless sensor network in other fields.
