Cross-Layer Architecture for Wireless Sensor Network

摘要

Complex applications and increased sensor capabilities will help prolife rate wireless sensor networks into everyday life. However, as sensor nodes are battery-operated, sensor networks will require protocols to spare every possible bit of energy. This Paper accomplished through cross-layer protocol that specialize the protocols for specific application requirements. However, as it continues to contribute to the field of sensor networks, protocols will evolve, and more efficient work will replace older ideas. Therefore, flexibility and eased maintenance of the network will be required to make sensor networks feasible for new deployments and customers. Here in this paper competing goals of energy-efficiency, achieved by specialization through cross-layer protocol design, and flexibility, achieved through modularity in a layered protocol design. With the development of micro-electronics technology, computing technology and the wireless communications technology, wireless sensor networks (WSNs) have been great concerned in recent years. The architecture of WSN directly affects entire network performance, and the network performance affects the availability of WSN. This paper specifies the design of WSN architecture where it is need to consider many aspects, such as deploy, energy consumption, expansibility, flexibility and error tolerance.
