The Research of Cross-layer Routing Protocols for Wireless Sensor Networks

The sensor nodes of wireless sensor network have small size and use battery-powered. Thus the processing and storage capacity, the communication range, energy and other issues of a single node is limited. However, the adjacent nodes in the shared channel can easily cause collision in data transmission, this not only leads to increase packet loss
