Research In Energy-efficient Communication Protocol For Wireless Sensor Networks

One of 21st century most important technologies-- the automatic disposition wireless sensor networks (WSNs), has the extremely high value in civil and the military aspect, its development and the widespread application, will bring the enormous impetus to people's social life and the industrial transformation. It has great many new characteristics to mobile communication network, wireless local area network, Ad Hoc network and such common wireless network .There are many hot spot in the research of WSNs.The wireless sensor networks is composed by the energy limited node. It takes wireless corresponds matter to gather and process useful data from the specific region, therefore how to do gathering and processing by the energy effective way, and guarantee the biggest lifetime of the network is a research key of WSNs, namely energy question. Recently, with the technical development, as well as the wireless sensor network own characteristic limit, the layered protocol design method has the certain limitation in the wireless sensor network application. Thus, this article integrates energy question and communication protocol, mainly uses the crosslayer design to propose a new energy effective communication protocol fuses the MAC layer and the route layer. The proposed protocol considers the influence to route mechanism from the route hop number, node position, energy consumption of each node. The simulation result indicates that the proposed algorithm can remarkably reduce the network energy consumption, enhances the energy efficiency.
